    About STILLEN Parts & Accessories

    Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

    With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.

    1. Very Impressed review by Rusty on 4/18/2018

      I was tired of my old Nismo intake. It was loud, flimsy, and the sheet metal box was on its last legs. I couldn't put my old box back in because I had thrown it out on a cleaning spree. So I had my eyes out for a replacement. When I saw this one on the Stillen site, I saw some things I really liked. It reused the factory air "pipe," which mounts to the front engine cover in two spots and is (I suspect) quieter than an aluminum pipe. The air-box on the Stillen is completely enclosed (quieter than Nismo) AND draws air from the driver side fender instead of the engine bay. When it arrived, I was even happier. It is very nicely (precisely) engineered for an air box. For some reason I expected the air box to be fiberglass, but it seems to be made of a sturdier plastic; somewhere between PE, ABS, and acrylic. Unlike the flimsy Nismo air box, the Stillen has an attachment point on the bottom that aligns perfectly with the factory screw stud on the top of the fender. One addition I made was placing a layer of sound deadening material on the inside of the screw down cover to help it seal tighter. ALL hardware is included, if you buy one and can't find it, unravel the brown paper package cushioning material. That's where mine was hiding.
