Many popular late model engines are notorious for dropping intake seats. These powdered metal seats break into small fragments and become lodged into the intake manifold. If you do not properly clean the intake they will get sucked into the new engine and contaminate it, causing damage to the new engine.

​

We highly recommend the intake manifold assembly be replaced to eliminate this problem. If you choose not to put a new intake on, the existing intake must be thoroughly cleaned.

​

To clean the intake, begin by removing the throttle body and standing the intake on end. Blow air through the intake ports to help dislodge some of the foreign debris. Collect debris with a powerful magnet. Be sure to thoroughly shake the intake and use a light to check the corners so you don’t miss any of this material.
