How much sence does it really make to keep the stock intake,with all the restrictions.Would it not make sence to replace it with a short ram that is less restricted right,but the more i research this site the more options i read about intakes the more statements there are about keeping the stock intake.My past vechicle a chevy colorado 04 zq8, the K&N 77 series intake blowed my stock intake out the water.Why is it so diffrent with a turbo application.

Is the SPT intake and exhaust work as a good combo,how does it affect my warranty.

 

ask your local dealer about the intake and exhaust how it affects warrenty

and the stock one is efficient

 

SPT claims "up to 20hp" with the SPT catback and intake (WRX) and "up to 47 hp" with the SPT cat-back and intake (STI). It is warranty friendly and a safe mod for a few extra ponies. The comination is called a "power pack" by SPT.

Yes, I work at a dealership.

 

Not all dealerships are cool like yours. I would call first just to be safe.

 

guess i have to get in contactwith my dealer.

 

Because the stock box is good up to 350-375 bhp (roughly 275whp).The SRT is the same way.Its not really a turbo thing,just some designs are better than others.Thats why some engines respond better than others to intakes.Not all intakes make goobs of power on N/A cars.Plus it very easy to moddify the stock box to flow more if needed.
