It’s all about maximizing what you’ve got, and trust me, this setup is a game changer.

Why Go for This Kit?

After countless hours on the flow bench and dyno, we’ve dialed in a combination that can push your power up by over 70 HP, depending on your camshaft choice and any other mods you might have. You get a serious boost in performance without sacrificing drivability—because who wants a car that’s a pain to drive on the street?

What’s Included
