This kit features a flat spacer yielding the best overall gains. The Motordyne 5/16" plenum spacer outperforms the competition while keeping your strut bar and engine cover in place. This stealth modification adds 11HP-13HP and is very simple to install. All Motordyne spacers are melt proof plenum spacers. They come with quality parts, pre-attached gaskets and self sealing plenum internal supports for OEM reliability.
