\n\nSUBARU IMPREZA EJ205, EJ255, EJ257 THERMAL INTAKE GASKET - IM115\n\nAPPLICATION:\n\n--\n\nSUBARU IMPREZA\n\n2.0 EJ205 WRX / STi 2001 - 2006\n\n2.5 EJ255 WRX 2005 - 2007\n\n2.5 EJ257 WRX / STi 2004 - 2014\n\nFor every 3.3 \u00B0C rise in intake temperature, air density drops by 1%. The hotter the air entering your engine, the less fuel the computer injects to compensate for reduced oxygen.  \n\nThermal Intake Gaskets reduce air intake temperatures by removing the direct contact between the cylinder head and intake manifold surfaces where heat soak usually occurs. The PTFE thermo plastic has unique thermal resistant properties which standard gaskets simply dont have.  \n\nAn intake temperature drop of around 10 degrees C is expected when using these gaskets on a road driven engine, which is good for around 3 percent power increase. Better results can be expected with track driven applications where heat soak is much more noticeable between pit stops. \n\nFeatur;
