Description
This is the 5/16 Stealth Plenum Spacer Upgrade for the 03-06 350Z, 03-06 G35 Sedan, and 03-07 G35 Coupe VQ35DE Engines. Gains from 12-14HP, simple and easy install. Works with OEM Strut Bar and Engine Cover. Iso Thermal Spacer Reduces Heak Soak and helps prevent power loss. Iso Thermal Gasket also allows upper and lower plenum to run cooler.
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.

Easy installation with all the instructions needed. Happy with this purchase for my 2006 350z.
Great product! Had no issues when installing and noticed more kick off the line in a track, have had it for about 2 years now and never had an issue.
