[trueno86power]

Since I've switched to the stock exhaust with the UEL Borla headers it missed a little bit of engine noise. I've tried again the Injen SRI... I had it on my first FR-S and it was terrible, lost of low end power and hard bucking below 2000RPM (lot of intake have this problem and is documented somewhere on the forum)

They revised the system, now the air filter is sealed with the bumper OEM air suction tube so no more MAF turbulance ! It sounds great and I did not had any power loss in low RPM, in fact It gave me some hp in the high revs. Even better, the A/F is pretty similar to what I had !
