STM E85 Safe FPR Kit for Evo 8/9

Moises Cruz (Kissimmee, FL, US)

Thanks for everything

FPR Kit - Evo 8/9

Great kit, looks awesome. STM answered all my questions and gave great advice. Best place for everything

andrew (Costa Mesa, CA, US)
Perfect kit

All of the parts are high quality and there is plenty of extra length in the provided lines for different placement options.

My only complaint(and it's barely a complaint) is that you're kind of left to your own devices as far as placement. There are no suggestions on where people usually mount the FPR. I ended up mounting mine to the side of the intake manifold where the stock FPR solenoid was before install and that worked out well.

That said, very happy with the kit.

Thank you for the awesome feedback, Andrew! We appreciate your business, and your feedback.
