Description

Precision-machined oil pump and cam plate are crafted from billet aluminum with a blue anodized finish for lasting durability.

Passage plugs are removable for servicing, and independent scavenge sections handle the flywheel cavity and cam chest to improve oil control.

Debris screens in both scavenge pickups and increased oil flow capacity on both the feed and scavenge sides enhance reliability under demanding conditions.

The adjustable pressure relief valve can be tuned with the unit installed in the engine for convenient setup.

Includes premium tappets and billet aluminum tappet cuffs with a hard-anodized black coating to eliminate distortion and improve tappet stability in high-lift situations.

Includes cam chain tensioner and will fit M8 with VVT.

Made in the USA.
