Roger Clark Motorsport Cylinder 4 Cooling Mod Kit - Street Spec, 2002-2014 WRX & 2004-2021 STi

Cylinder 4 cooling has long been a known issue on the EJ Family of Subaru engines.
The nature of the water passageways around this area means a lack of cooling can lead to an increase in the temperatures around this cylinder. RCM's simple solution to this problem lies in our easy to fit complete kit.
Kits are Right Hand Drive and Left Hand Drive Specific.

Included:
• CYLINDER 4 COOLING MOD KIT - STREET SPEC
• 4 x Hose Clamps

Features:
• Billet fittings
• custom 90 degree Samco silicon hose
• Hi-Grip stainless steel fittings
• correct diameter to allow the right flow rate around cylinder 4 to cool without over cooling
• flow is maintained without disturbance from potential kinks in the pipework.
