Subaru Top Mount Intercooler
Top Mount IntercoolerA key to making more power on any turbocharged engine is the addition of a high performance air-to-air intercooler. This part in the simplest of terms, cools the air going from the turbo into your engine, much the same as a radiator cools the water inside the engine, by transferring the excess heat way using multiple passages through a core. A PERRIN intercooler fits easily to the front of your Subaru to maximize cooling. |

Intercooler CoreThe most important part of any intercooler system is the core. The core cools the charge air on the way to the engine. The factory Subaru tube and fin intercooler was designed to be easy to manufacture, but is not good for performance.Our testing has shown the optimum core design is the 3/8” bar and plate style that has a 3/8” charge air and ambient air path, instead of the common 1/4” size. The PERRIN bar and plate core design is much more durable than tube and fin with the ability to withstand rocks and other debris, which may enter the scoop. |
|
Cast EndtanksThe PERRIN Performance designed endtanks control near perfect dispersal of hot air across the intercooler core. BY eliminating any 90 degree corners adding a smooth, gradual taper from top to bottom turbulence is eliminated. Each endtank has an innovative mounting tabs built in that can solidly remount the factory intercooler cover. |
|
Pressure TestingPERRIN Performance is one of the only intercooler manufactures who pressure tests every intercooler. We pressurize every intercooler to 50 psi. on our special jigs. This ensures you never get a core with a leak! Even the slightest leak can cause your vehicle to loose power, literally bleeding turbo boost pressure out the intercooler. |

|
FinishEvery PERRIN intercooler is powder coated to further protect your intercooler from the elements and making it look awesome for years to come. Available with either a black or silver powder coating. |
|
PERRIN StencilsIncluded with our front mount intercooler is a free PERRIN logged intercooler stencil. Use the stencil to easily paint the PERRIN logo across the front of your intercooler. Simply peel stick paint and remove. |

Top Mount Intercooler TestThis was done on our 08 WRX running Stage 2 with a PERRIN intake installed. We did nothing but swap to the larger intercooler between runs. You can see on this that the freer flowing, more efficient intercooler makes about 10WHP more with no additional ECU tuning. With Stage 3 mapping you can expect to see about 10 more additional WHP! |
