ZZP LSJ Phenolic Intake Spacer

A hot engine heats up the air that is flowing through your intake. The engine is aluminum, as is the intake and they conduct heat very well. Your 180 deg engine adds unwanted heat to the LIM which houses the intercooler. That is why you need to upgrade with our ZZP LSJ phenolic spacer. A cooler charge will make more power. Keep in mind that removing heat adds power not only by increasing air density, but also by helping cool your IAT2s down to help prevent detonation.     We isolate the intake from 95+% of its contact to the engine which is what is heating it up. See pic below showing that the heat from the engine is isolated where the intake connects to the engine.  The engine runs at approx 185 deg and has a direct metal to metal contact with a large surface area on the intake. This is constantly trying to heat the intake/IC system/blower to this temp. This puts additional heat into the IC system and is the reason on summer days you will see IATs at idle/cruise 40 to 60 deg over ambi
