These Subaru WRX Racing Camshafts with 282° High Lift EJ20 Engine Non AVCS Cams are made for wide open throttle and high rpm power motorsport purposes. They work best for competition EJ20 engines with 64-72mm turbo and larger intake manifold. If you're looking to use E85 fuel, they are ideal for you! Keep in mind that fitting high lift cam lobes requires cylinder head modification and shimless buckets.

Kelford Cams suggest a valve spring upgrade with their KVS1847-BT.
