Our products

CPIs global product portfolio consists of eight product groups; starters, alternators, AC compressors, brake calipers, EGR valves, steering racks, turbochargers, and intake manifolds.

We have a large base of more than 13,500 part numbers crossed with a large quantity of OE numbers. For each product group, we target to achieve coverage of more than 90% of the European car park – offering you as a customer a broad selection of products that fit your needs.

CPI does not compromise on quality and service. We have developed expertise in a wide range of remanufacturing technologies, which provide us with a competitive advantage when it comes to collaboration with renowned automotive OE players. Such partnerships permanently and systematically challenge us and put into practice one of our main values; continuous improvement.

    To start, an internal combustion engine needs fuel, compression, and a spark, in the case of petrol engines. The function of the starter motor is to use energy from the battery to rotate the crankshaft for the cylinder to create the required compression for the initial start-up of the engine.

    Our range of starters consists of more than 2,300 part numbers. Such a large program enables us to cover 95% of the European passenger car park. We also have substantial coverage for trucks, buses, marine, agriculture, industrial, and light commercial vehicles. Each starter’s design has its strong points and weaknesses. Throughout a long history of data records, we managed to identify these weaknesses to develop the best remanufacturing process, which often involves reverse engineering.

    This means that in addition to our standard remanufacturing process, which involves the systematic replacement of many worn components with new ones, we frequently use reinforced steel planetary gear rings or completely new OE drives in our starters. We pay high attention to the proper sealing of the starter for water resistance, and each remanufactured or new solenoid is tested before the final test of the assembled unit. Our end-of-line test integrates top-notch technologies, and among many parameters, it will test the output power, torque, current, free running speed, solenoid pull-in, and holding current and will generate a detailed and individual performance test report. Needless to say that we remanufacture only OEM products.

    In passenger cars, an alternator provides current that will be used to charge the battery and power the electrical system. The alternator rotor is connected to the internal combustion engine through a belt, and the rotor motion will induce a current in the stator windings. A voltage regulator is in charge of controlling the excitation current passing through the rotor; thus, the output voltage generated. Combined starters/alternators are reversible alternators that can start the internal combustion engine in start/stop systems.

    With a range of more than 3,400 alternators, our program of remanufactured alternators covers over 93% of the European car park. The alternator program of CPI includes alternators for passenger cars, commercial and agricultural vehicles, marine, and industrial vehicles.

    Every single remanufactured alternator within the CPI range has been developed by using advanced reverse engineering technics. Our new part introduction (NPI) relies on a stringent and systematic implementation process.

    Every CPI alternator is professionally remanufactured by using high-quality spare parts and efficient processing methods. All critical components are 100% replaced with new parts.

    100% of our alternators are full-load tested to guarantee strict performance specifications, while product diagnostic ensures 100% vehicle communication network fitting. Our alternators are individually labeled to ensure state-of-the-art traceability.

    An air conditioning compressor is responsible for compressing and moving the refrigerant into the condenser and evaporator. The evaporator will absorb heat from the air entering the passenger compartment. The compressor can be a piston, scroll, or vane type and is either driven by the accessory belt or an electric motor.

    We offer a range of more than 1,300 compressors, which means that we have one of the widest ranges of compressors on the market, covering more than 95% of cars in Europe. All of our AC compressors are delivered as a plug-and-play solution and prefilled with the correct oil type. Our compressors have to meet precise suction/discharge, pressure, noise, leak, and vibration parameters, as well as power consumption. Other components, control valves, the compressor shaft, and the clutch, play an important role in the compressor’s performance, and our control plan includes a 100% pre-test of multiple sub-components before final assembly.

    Brakes are meant to slow down or stop a vehicle by converting the energy of motion into heat using friction. In passenger cars, hydraulic pressure generated by the driver and brake booster is used to apply force to the wheel assembly. In disc brake systems, the brake caliper will convert this pressure into a force applied on the brake pads. Brake calipers can be fitted with mechanical or electric parking brake systems.

    It is amazing how many different OE caliper designs have been developed over time. Our brake caliper program includes more than 3,850 part numbers segmented into technology families and covers 96% of the passenger and light commercial vehicles in Europe. Each of our steel calipers goes through a coating treatment that provides efficient and effective corrosion protection. Note that the coating process is also done in-house, allowing us to fully control the production process. Our caliper program is not limited to hydraulic calipers; it also includes remanufactured electric parking brakes. While ensuring the functional and performance aspects at 100%, we invest significant time and resources in the cosmetic aspect of our calipers too. In terms of functionality and performance, the piston area is, among other aspects, critical in a caliper, and of course, micro finish specifications are well integrated into our control plan and FMEA. The brake caliper is a safety-relevant product, and we are proud to benefit from the trust of our customers and to remanufacture massive quantities of calipers every year.

    By rerouting exhaust gases from the exhaust into the intake, exhaust gas recirculation (EGR) valves can significantly reduce the emissions of nitrous oxides, known as NOx. NOx generation takes place in the combustion chamber at high temperatures. EGR valves introduce gases inert to combustion that absorb a part of the combustion heat, thus reducing the combustion temperature. Those valves can reroute the exhaust gases from the exhaust manifold upstream of the turbocharger (high-pressure EGR) or after the Diesel particulate filter (low-pressure EGR).

    EGR valves efficiently reduce Nitrogen oxide emission. At preset load conditions, the valve lets in exhaust gas to the air intake, thereby adding less oxygen for combustion in the cylinders, thus lowering the temperature, which then reduces the formation of NOx.es

    A steering rack is a mechanical assembly that is capable of converting the rotational motion of the steering wheel into the lateral motion of the front wheels in order to steer the vehicle. Additionally, power steering racks generate a force to assist the driver in turning the wheel while providing an adequate steering feel. The assistance force can be generated by hydraulic pressure or an electric motor; however, electric power steering racks have become the dominant technology thanks to their ability to reduce fuel consumption.

    With more than 20 years of experience in the remanufacturing of steering, CPI holds an extensive steering rack program for European applications on both left and right-hand drive vehicles.

    Our power steering racks, manual, and electric racks are remanufactured at our UK facility in Wednesbury, which is fully dedicated to steering technologies.

    Our program covers passenger and light commercial vehicles of all makes, and new applications are being constantly added to the program.

    CPI has recently invested heavily in a new state-of-the-art test bench, which is fully automated and delivers a more stringent assessment, which allows our company to increase its capacity while securing a premium quality product for our customers.

    To ensure product quality, all seals, rubbers, and worn components are fully replaced, and each remanufactured unit undergoes a two-stage test, the first being an air test and the second being a functional hydraulic test.

    All EPS systems are tested at three different speeds and loads which simulates how it works on a vehicle.

    All electronic components used in any of the EPS systems are tested before being used in the remanufactured unit.

    All remanufactured steering units are fully traceable back to the individual test results providing full traceability of product performance.

    Exhaust gases coming from an internal combustion engine contain both thermal and kinetic energy. A turbocharger uses this wasted energy to compress the intake air. A turbine pushed by the exhaust gases drives a compressor, increasing air density in the combustion chamber, which enables more oxygen and more fuel to be injected in the same volume, achieving higher torque and higher engine output.

    Turbochargers can reach speeds up to 400,000 rpm at temperatures up to 950°C, which makes them a complex product where highly specialized materials, precise tolerances, and balancing are key. The latest turbocharger technologies, such as variable geometry, also require extra steps, such as precise actuators and minimum flow adjustment.  By increasing volumetric efficiency, turbochargers enable manufacturers to downsize engines, reducing vehicle weight, moving engine operation to high-efficiency areas, and reducing friction losses.  ​

    Our range of turbochargers features more than 850 part numbers, and such a large program enables us to cover 83% of the European passenger car park. Our new part introduction (NPI) relies on a stringent and systematic implementation process. Every single remanufactured turbocharger within the CPI range has been developed by using advanced reverse engineering technics. The highest quality is guaranteed by the systematic replacement of critical components with new ones, our thorough balancing, minimum flow adjustment, stringent tests, and traceability of each unit.​ Needless to say that we remanufacture only OEM products.

    Intake manifolds' main function is to deliver air, or an air and fuel mix, to the engine’s cylinder head. They can, however, perform other functions, such as actively optimising resonance charging or air and fuel mix. The latter is sometimes achieved with the help of swirl flaps, also referred to as tumble flaps. Gas dynamics, such as swirl and turbulence, play an important role in the intake charge mixing. They help regulate the fuel-to-air ratio, improving emissions and generating better torque at low engine speeds. Still, excessive swirl patterns can limit the piston intake capacity and engine efficiency. A solution to this issue is the variable flap valve system. This system can adjust the swirl of the intake air based on the engine load and speed. At low rpm, the flaps close for the air to make a more swirling motion within the cylinder, allowing a better fuel and air mix, good torque, and low emission. At high RPM, it opens to allow more air and fuel to develop maximum power. Those intakes can use different materials, such as plastic, aluminium, or a combination of the two, electric or pneumatic actuators as well as other communication protocols.

    Our new part introduction (NPI) relies on a stringent and systematic implementation process. Each single remanufactured swirl intake manifold within the CPI range has been developed using advanced reverse engineering techniques. The highest quality is guaranteed by the systematic replacement of critical components with new ones, coating treatment providing efficient corrosion protection of the components, stringent leakage and functional tests, and traceability of each unit.​ Needless to say that we remanufacture only OEM products.
