We were the first to design and develop a performance induction kit which can be remapped using the stock maf housing for the


Peugeot 208 GTi , 308 GT, 308 GTi II, RCZ 200THP, RCZ-R 270THP & Citroen DS3 Performance.


During our extensive test and development program we ensured by using load dynos for over 8 hours that our kit delivers more power and torque on all the maps we could test.


We took an indepth look at the design of a restrictive OE Euro 5 and Euro 6 airbox on the Citroen and Peugeot EP6 engines so to design our RCTS-CF hybrid that fits several models including the Citroen DS3 performance, 208 GTi, 308 GTi, 308 GTi ii, RCZ 200 & RCZ-R.


Our racing RCTS intake kit is larger than the stock airbox and comes with a carbon fibre heatshield


Cold air intakes are important for any car, air is fed to the airbox via the front air intake scoop which is situated in front of a cars radiator. The cool fresh air travels up the lower intake hose into the base of the airbox.  RCTS intake kits are larger than the stock airbox so this allows the air pressure to be lower thus increasing oxygen density, partly the same principal of intercoolers and plenums since they are larger and the pipework is longer so causes a drop in pressure. The less compacted air is the more ability the molecules have to carry oxygen. The opposite is true for turbos, they compact air into a small space (so to squeeze more in past the intake valves) which makes the air very hot.  The turbo compressor wheel is spinning from the exhaust gas which sucks air from the cold air intake where it is measured by the maf sensor for volume then travels down through the turbo inlet hose and into the turbo where it is compressed. The air (oxygen) is then passed through the fmic so to cool it via convection. When the air comes out of the intercooler flange it passes up and through the turbo boost pipe and into the inlet manifold. The air is measured / metered for density  by the map sensor on the boost hose and again by a map sensor on the inlet manifold. The ecu calculates how much fuel to add , the fuel injectors via the fuel rail and hpfp supply the correct amount of fuel. This is ignited by the spark plugs at the optimal point in time once compressed by the pistons. That gas then exits the cylinders as the exhaust valves open. The hot gas travels out through the exhaust manifold travelling past the turbo exhaust wheel (the hot side) which spins the turbo as the gas then exits via the downpipe; the ecu uses O2 sensors to measure the exhaust gas as it travels past then into the cat-back so to exit the rear of the car. More air will be drawn from your RCTS cold air intake as engine rpm increases which is dictated by the throttle body.


RCTS has a heatshield due to the nature of using panel filters, if there was no full enclosure it would be possible on the panel filter version for dust , debris, oil and coolant to enter the engine since the panel air filter sits below the intake area not above.  The cone filter version filters the air at intake level.


Our intake kits have proven to produce over 310hp and RCTS should be capable of delivering enough air for 450hp.


RCTS-PF = Panel filter Version

RCTS-CF = Cone filter Version



It is possible to fit RCTS on other 3 legged PSA airbox bases which do not have a maf sensor by simply purchasing one and blocking where the electrical connection is so that no air can escape or enter through that opening. Example of this could be a Citroen DS3 Racing or a 207 GTi / RC.


*Please note this is a tuning product, service intervals on your car can be higher due to modifications and increased wear and tear on other parts may also be evident. It all depends on how much power your map is running. Please see our remap section for more information on such modifications.
