Just lettin y'all know I have had this intake on the truck about 6 months now and couldn't be any happier best intake on the market hands down! When someone asks me about what intake they should buy I recommend RPI


This is by far the best intake out on the market. Beautiful look to it with the candy powder coating. My air temp has gone down alot from the stock intake. The turbo whistle is magnificent! you can hear it in idle and perfect volume while driving. Also makes the exhaust brake sound like a jake brake which I love.

The intake made a noticeable power increase. And keeps the engine temp down. Very impressed with the craftsmanship that went into makeing the intake.
