IDP 3″ Plenum will not crush from too much boot clamp pressure, and withstand high amounts of boost! We use these on all our race cover S400 trucks and have been over 1000hp with them with no issues!

Please be sure to select your head type options.

Early head type requires an 8 bolt hole Plenum.

1995 and up head requires 10 bolt hole Plenum.

Qty included is 2 per set, one for each cylinder head.

**Will work with 94-97 7.3L STOCK turbos but you will have to source the correct boots as we do not carry them.
