APR tested the OEM intercooler and their FMIC upgrade on the dyno doing six back to back pulls. The OEM intercooler lost 25 horsepower compared to the APR unit. So yes, the APR unit helps lower air temps and the car retain power quite a bit.
Even after the first run the APR baseline was higher at 380 wheel horsepower compared to the OEM IC at 362 wheel horsepower. A difference of 18 horsepower at the wheels. This difference only got larger after six pulls with the APR unit measuring 368 wheel horsepower to the OEM's 345 wheel horsepower. A difference of 23 wheel horsepower.
Worth the $1699 asking price? Definitely. What more is there to say? A solid product and solid data from APR as to be expected.
