Honda SOHC VTEC (ALL)1988 - 2000 Honda Civic (CX, DX, EX, GX, LX)1988 - 1991 Honda CRX (Base, HF, Si)1987 - 1987 Honda Wagovan (DX)Hondata have developed a special high temperature insulating gasket which replaces the stock intake gasket. This and bypassing several heat sources significantly reduces the transfer of heat from the head to the intake and incoming air giving you up to 5% more power.Turbocharged cars often use an aluminum intercooler to cool the air compressed by the turbo. The intake manifold is also made of aluminum but because it is heated by the head from combustion and coolant, works in reverse to an intercooler by heating the intake air by as much as 50° C.Fact: For every 3.3 °C (5° F) rise in intake temperature, air density drops 1%. The hotter the air, the less fuel the computer injects to compensate for reduced oxygen. HondaLogger datalogging software has enabled us to measure intake air temperature under varied driving conditions.Around town, testing has shown an
