4.9/5 · 750+ verified eBay reviews
“Works excellent and sounds amazing! I was a little hesitant to not buy name-brand at first, but upon receiving the intake I was extremely impressed on the build quality. The intake is a one-piece molded unit that fits very well in my 2016 RXP. I have zero complaints and I love hearing the supercharger flutter when you let off the throttle. If you're not concerned about name brand this is the way to go.”

“Power everywhere — on plane faster, more grunt, sounds meaner than with the stock air box. Great upgrade.”
