Kelford Camshaft for Subaru JDM Version 7-10 EJ20 w/AVCS

This range of Kelford high performance camshafts is to suit what we call the JDM Version 7-10 EJ20 engines with Subaru's awesome AVCS (Active Valve Control System). The cams are easily identified by the triggers on the rear of the intake cams, they are machined to have four protruding 'paddle wheel' style triggers. If your engine has the three 'keyway / slot' style triggers, you need to see our EJ25 range with the R-199 part numbers. This range of camshafts feature high velocity lobes that have a wider 'sweep' across the cam bucket, therefore these camshafts can only be used on shimless buckets or buckets that have the shim underneath. These profiles can not run on the earlier 1999-2001 Version 5-6 buckets that have the shim on top.

Racing camshafts to suit AVCS engines, works well in near stock engines but with turbo and ecu upgrade, ideal for 350-500hp road car or track day applications.
