DriftMotion Intake Gasket Set -Upper and Lower
This heat shielding gasket goes between the lower intake runners and the
cylinder head, reducing heat transfer between the head and the intake plenum and
fuel injectors. They are used on many high performance import cars with much
success, so we thought the 1JZ guys should have access to them too!
Includes both the Upper and Lower intake gasket. (Fits vvti and non-vvti 1JZ
Typical results with a heat shielding gasket would be a 17-20 degree (F) drop in
intake plenum temp, and a 8-10 degree F drop in intake air temp.
