Roger Clark Motorsport have developed their own high performance induction kit for STi cars (from 09/1996 to 01/2000 and also WRX cars from 08/1998 – 01/2000) allowing greater unrestricted air flow and improved engine response. This induction kit consists of a high grade aluminium trumpet which is finished in a tough silver powder coating. This kit utilizes the standard air flow metre assembly and K&N filter element RCM01. The cotton filter element stands 170mm high with a 160mm diameter mounting flange and a stainless steel clamping ring. Fitment of this kit is straight forward. Simply replace the standard air box assembly and then refit with this induction kit. It uses the standard induction hose.
