Great product
You can install this without removing anything on the engine. The only thing I recommend is to be careful when tightening the banjo bolts into the head. Awesome product my engine is significantly quieter and running more smooth.

HPX
Installed this in the dark with a headlamp on my 2000 F250 without removing anything from the motor. I noticed more stable idle RPMS immediately after installation and overall truck seems to be running more fluid, it doesn't feel like its chugging along as much. Well worth the money in my opinion, and huge thumbs up for Riff Raff on quick shipping and love the stickers and pens!

Great quality
Nothing much to say other than it works and looks high quality. $50 isn’t much money for a custom piece like this. The truck runs way better overall.
Thank you RF Diesel -
