8 product groups and more than 12,000 part numbers

Our products

CPI global product portfolio consist of 8 products group; starters, alternators, AC compressors,  brake calipers, EGR valves, steering racks, steering pumps, and turbochargers.  
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 a covering of more than 90% of the European car park.
CPI does not compromise on quality and service. We have developed an expertise in a wide range of remanufacturing technologies, which provide us a competitive advantage when it comes to collaboration with renowned Automotive OE players. Such partnership does permanently and systematically challenge us and put in practice one of our main values; continuous improvement.


In order 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 in order for the cylinder to create the required compression for the initial start-up of the engine.

Our range of starters counts more than 2,300 part numbers. Such a large program enable us to cover 96% of the European passenger car park. We also have a substantial coverage for trucks, busses, 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 in order to develop the best remanufacturing process which often involves reverse engineering. In concrete, it means that in addition to our standard remanufacturing process, which involves the systematic replacement of many worn components by 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. Each remanufactured or new solenoid is of course tested before final test of the assembled unit. Our end of line test integrates top-notch technologies. Among many parameters, it will test the output power, the torque, current, free running speed, solenoid pull in and holding current etc.... 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. 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 starter/alternator are reversible alternators that are able to start the internal combustion engine in start/stop systems.

With a range of more than 3,300 alternators, our program of remanufactured alternators covers more than 95% of the European car park. The alternator program of CPI includes alternators for passenger cars, commercial and agricultural vehicles, marine, and industrial vehicles.

Each single remanufatured 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 into new parts.

100% of our alternators are full-load tested to guarantee strict performance specifications. Product diagnostic ensures 100% vehicle communication network fitting. Our alternators are individually labelled in order to ensure a state-of-the-art traceability.

AC Compressors

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 either driven by the accessory belt or an electric motor.

We offer a range of more than 1,200 compressors, which means that we have one of the widest range of compressors in the European market, covering more than 96% of the cars in Europe. All our AC compressors are delivered as plug & play solutions; prefilled with correct oil type. Our compressors have to meet precise suction/discharge, pressure, noise, leak, vibration parameters as well as power consumption. Together with other components, control valves, compressor shaft and clutch play an important role in the compressor performance. Our control plan includes a 100% pre-test of multiple sub-components before final assembly.

Brake Calipers

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 in order to apply a force to the wheel assembly. In disc brakes systems, the brake calliper will convert this pressure into a force applied on the brake pads. Brake calipers can be fitted with mechanical of electrical parking brake systems.

It is amazing how many different OE caliper designs have been developed over time. Our brake caliper program includes more than 3,700 part numbers segmented in technology families and covers 96% of the passenger and light commercial vehicle car park in Europe. Each of our steel caliper goes through a coating treatment providing an efficient corrosion protection. Note that the coating process is also done inhouse, allowing us a full control of the production process. Our caliper program is not limited to hydraulic calipers, it also includes remanufactured electric parking brakes. While ensuring the functional and performances aspects at 100%, we invest significant time and resources on 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.

EGR Valves

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 temperature. EGR valves introduce gases inert to combustion that absorb a part of the combustion heat, thus reduce 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 spillage of Nitrogen oxide. 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.

Steering Racks

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

With more than 20 years of experience in the remanufacturing of steering, CPI holds an extensive steering rack programme for European applications both left and right hand drive.
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 programme.
CPI has recently invested heavily in a new state-of-the-art test bench, which is fully automated and delivers a more stringent test, which allows our company to increase its capacity while securing a premium quality product to our customers.
In order to ensure such product quality, all seals, rubbers and worn components are replaced 100% and each remanufactured unit has gone through a two stage test, first being an air test and the second being a functional hydraulic test.
All EPS system are tested at three different speeds and loads which simulates how it works on vehicle.
All electronic components used in any of the EPS system are tested prior to it 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.

Steering Pumps

Steering pumps create the hydraulic pressure required by the power steering system. Traditional steering pumps are vane, gear or piston type driven by the accessory belt of the engine. Electric steering pumps are power on demand systems capable of reducing fuels consumption related to the generation of hydraulic pressure in traditional power steering systems.

With more than 650 items, CPI’s program of power steering pumps offer a comprehensive coverage in Europe of both passenger cars and commercial vehicles.


Exhaust gases coming from an internal combustion engine contain both thermal and kinetic energy. A turbocharger uses this wasted energy in order to compress the intake air. A turbine pushed by the exhaust gases drives a compressor increasing air density in the combustion chamber. This enables more oxygen and more fuel to be injected in the same volume, achieving higher torque and therefore higher engine output. Turbochargers can reach speeds up to 400 000 rpm at temperatures up to 950°C which make them a complex products where highly specialized materials, precise tolerances and balancing are key. The latest turbocharger technologies, such as variable geometry, also require extra steps as precise actuator 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 counts more than 700 part numbers. Such a large program enable us to cover 71% of the European passenger car park. Our new part introduction (NPI) relies on a stringent and systematic implementation process. Each single remanufactured turbochargers 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 by new ones, our thorough balancing, minimum flow adjustment, stringent tests and traceability of each unit.​ Needless to say that we remanufacture only OEM products.
