Review on 🚀 Fleece Performance Engineering FPE-INTAKEHORN: High Flow Intake Horn for 01-04 GM Duramax 6.6L LB7 by Eddie Man

Noticeably more than in stock. It is painted black. Slots for the two bottom screws made installation much easier. Supplied with seal. I have installed on Duramax 03 with California EGR. Getting the old one out was a challenge as the passenger latch was a struggle. After breaking it, I had to use long tweezers to take it off as a wrench or fingers wouldn't fit in the tiny gap. The fleece is light and fits great even with AGR. At the same time I installed a Specter cold air intake and now the turbo whistles like crazy. Sounds incredible. Added more power and lowered the EGT.
