Injen 08+ STI / WRX Cold Air Intake - Whats in the Box?

[xAbre1200]

+38 HP.... I'm not too sure about that Injen. Nice intake though.

[PantstofryPWNZ]

@xAbre1200 Maybe calculated at the crank or something, i dunno. Probably ran in perfect conditions.

[jasminemyfirst]

Would this intake need to be tuned?

[Killer91109]

Does this make the stock BPV sound louder?

[rallysportdirect]

@Killer91109

Yes, this intake will increase the noise from the stock BPV.

[shizzel122]

@Killer91109 its actually the internal waste-gate that you here opening more

[wudi911]

do i have to flash the ecu?

[rallysportdirect]

@wudi911

According to Injen, tuning is not required for this cold air intake

[ejicon]

@wudi911

If you want the MOST out of this intake... YES!

but like Rallysportdirect said.... it's not required.

[SurGTC1]

i love my intake ..gives me great gas mileage and sounds badass .. GO INJENN

[blackhawk60m]

You can't just throw it on though. The MAF is way too sensitive and will cause the car to tun lean. It needs a tune with it.

[wudi911]

what kind of factory warranty?

[rallysportdirect]

@wudi911

Injen proclaims this product to have a Limited Lifetime Warranty

How much horsepower gain will I get for my stock 08 wrx?

[rallysportdirect]

@ChuckManiac

According to Injens dyno chart they achieved +18lbs of horsepower and +8 lbs of torque.

[spdarkjoe]

yeah its legal in california.

[Mogul20478]

Does anyone have an actual dyno spreadsheet or some form of proof that this intake will add 38 hp? Doesn't seem likely, and sounds kind of exaggerated. Is that with a tune? With other parts? Or will this start making that HP straight after install.

[BBSroll]

wont the heat shield get in the way from the FMIC?

[tottibas]

will this intake also fit 04-07 sti's?

[rallysportdirect]

@tottibas No it will not.

Injen does make one designed for the 04-07 STi though
