Hannah ★★★★★

I was worried about fitment, but this module dropped right into my 2002 Civic without any modifications needed. The fuel pressure is rock-solid now, and the plug-and-play harness made installation a breeze.

Joseph K. ★★★★★

My 05 RSX fired right up after swapping in this module—the direct-fit design saved me hours of modification work. The fuel pressure is rock steady now, and the install was cleaner than I expected from an aftermarket part.

John L. ★★★★★

Had a slight pressure issue with my old pump on the RSX, but this module dropped right in and my fuel delivery is rock solid now. The direct-fit design saved me from having to rig anything up.
