Zach (Columbiaville MI) | May 3rd, 2021
Absolutely unbelievable the difference just the intake alone makes. I did install everything and a fass 165 at the same time and it really helped my truck breath. It however didn't help with EGTs as much as I was thinking but still was better than before. The worst part about the install was the Y-bridge. I was too stubborn to remove everything else around (thinking oh I can do this) so I tried to install it with alternator and wiring harness still in. I highly recommend doing that part exactly how the instruction manual says or someone on YouTube 🤣 HSP did not disappoint that's for sure. Definitely recommend this product. Order #1240582
