Genuine Subaru EJ207 AVCS Spec C Big Port Cylinder Head Right Hand

Genuine Subaru right-hand cylinder head, fitted as standard to the 2.0 litre JDM Impreza Spec C, 2002 - 2007.

The JDM Spec C "big port" heads are widely regarded as the best-performing OEM cylinder heads made by Subaru. The enlarged port design gives a significant increase in gas flow compared with the UK/Euro EJ207 equivalent.

Compatible without modification with any Subaru EJ20, EJ22 or EJ25 block where the build uses AVCS on the inlet camshaft side only. These heads make a great basis for a valvetrain upgrade and can support high power levels out of the box.

Cracking around the spark plug thread is a common problem on later Subaru cylinder heads and often leads to a loss in performance. Spec C heads are a good choice to get the most from a new engine build.
