Suitable for all Clio 2RS 172 and 182 models.
The billet steel 5502438 camshafts are the result of the joint development program from the Belgian performance valve train specialist CatCams NV and leading Renault specialist K-Tec Racing Ltd. The 438 cams provide the optimum cam profile which can be used with OEM valve springs, both OEM RenaultSport ECU re-mapped management and our KTR GEN90 ECU.

Extensive testing on K-Tec Racings Dyno Dynamics rolling road in conjunction with an ECU remap has shown an impressive power gain of 18 bhp at 6250 rpm, with a torque increase of 10 lb.ft @ 5250 rpm.
The peak figures produced by this RenaultSport Clio 182 were a healthy 185 bhp @ 6500 rpm, allied to a substantial 164 lb.ft of torque at 5150 rpm. (NOTE: This test 182 already featured an ECU remap so owners of standard 172 / 182 Clios should benefit from an even larger power increase.)
