More details

This item has been discontinued by the manufacturer and is no longer available. For alternative products please contact us.

Iso Thermal Gasket also allows upper and lower plenum to run cooler. Copper Throttle Upgrade Recommended for areas that have Heavy Snow Fall or Salt on roads.


Please note: While longer bolts are included for the strut tower brace to clear the raised plenum, early 2003 models will require thinner bolts. These are not normally included with the kits from Motordyne, so we have added an option above to include an extra set of bolts for the 2003 MY.
