So you have a problem. You want to run a speed density conversion or blow through MAF setup on your 02-07 WRX or STI but don't want to spend the cash to have a straight pipe intake custom fabricated. Grimmspeed has the solution. With the Grimmspeed MAF sensor block off plate, you can block off any intake pipe that was designed to accommodate the stock MAF without any welding or fabrication work. This simple fix installs in mere minutes and allows you to keep your favorite intake kit even when you relocate or delete the MAF sensor. If you ever want to change your setup, this block off kit is fully reversible and completely undetectable.
