This is designed to help remove heat from the piston by spraying oil onto the underside of the piston. It is common practise in many high performance engines such as the Nissan Godzilla 2.6Ltr engine, Sierra Cosworth, Porsches, etc. We are the first manufacturer to offer this feature in Ford DOHC engines and it will be included in all of our Ford engines and rebuild kits from 2008.
