Our ZZP throttle body spacer will insulate your TB from residual heat and blocks the coolant passages to the throttle body. Keeping your TB cool will help keep your intake temperatures down thus reducing KR and increasing HP potential. 

For installation you will want to use RTV on the throttle body side of the adapter. We recommend the GM adhesive which can be found here. 

Fits L36 3800 engine. Sold individually.
