Sakura Fab: 4AG Heat Screen Intake Manifold Gasket

[dr.occa]

A 4C/7.2F-10C/18F degree change in air temperature (increase or decrease) will cause a 1-3% horsepower change. These gaskets will lower the temperature of the intake manifold by at least 11C/20F and benefit both naturally aspirated & forced induction environments.
