Have made a tentative order for a few HKS performance parts and wanted to get some opinions. Am planning to install a HKS down-pipe, HKS Hi Power exhaust, SQV BOV and a RS Suction Kit (you know, the one with the pipes and yellow filter). I was told power gains would be around 25 horses.

Appreciate any feedback.

 

for intake, dp, exhaust and bov i'd expect more than 25 hp but i could be wrong, i've seen some places sayin 30hp or more for exhaust alone
