Fleece High Flow Intake Horn for 2001-2004 Chevy/GMC LB7 Duramax
FPEFPE-INTAKEHORNThe cheapest bolt-on power you'll find for an LB7 is the intake horn.
The factory horn is a restriction. Fleece swapped it for this cast aluminum high flow horn and saw 15hp in back-to-back dyno pulls. That's about the cheapest 15hp from a bolt on you'll find anywhere.
Why it's worth it
- Up to 15hp gain in Fleece's back-to-back dyno pulls
- Cast aluminum construction
- Bolts on in place of the factory horn
What's included
- Cast aluminum intake horn
- New gasket

- Engine: 2001-2004 6.6L LB7 Duramax
- Part number: FPE-INTAKEHORN
Tuning with PPEI
PPEI recommends this horn for LB7 owners, and it's a part we like on our own trucks. Add PPEI LB7 engine tuning and the tune can make the most of the extra air coming through, for sharper throttle response, stronger pulls and a truck that runs more efficiently.
