Sophia ★★★★★

Dropped this in my K20 and the fuel pressure is rock solid now, no more stumbling under hard acceleration. The direct-fit design made installation straightforward, everything lined up perfectly with the factory hanger.

Andrew ★★★★★

Installed this in my 8th gen Si last weekend and it dropped right in without any modification to the harness or bracket. The fuel level readings are spot on with the stock sender, which surprised me for an aftermarket module.

Amelia ★★★★★

My stock pump was starting to whine, so I swapped in this direct-fit module—the K20 fired right up and idle is quiet again. The plug-and-play harness saved me from having to splice anything.
