I'm fitting this GT2 intercooler by HDi on my '05 Subaru Impreza SPEC C TypE RA. I've anotized the pipes in red for a better cosmetic result and because will be easy to clean them. The turbo is always the turbodynamics/Litchfield LM450-S60 fitted last year.
I changed the original intercooler because with high temperature (summer) the intake temp is high and the car lose power and torque. I changed also my gruppem cold air kit because no space in the engine room due to intercooler pipes. In 5 and 6 gear i get about 430ps with a boost of 1.8 peak and 1.6 costant.
So we used the HDI cold air kit. The BMC air filter that we can use it is not large but i hope it is good for the power i need.
