The HP gain from an SRT intake is very nice from stock. This is the one engine performance mod I did on my car that I was actually quite pleased with. If you have any questions on this intake...search around this site in the GO FAST section...plenty of SRT intake topics have been discussed in the past.newlex said:How much Horsepower will i gain from this? I am familiar with the AEM intakes for honda's and stuff but i am new the IS300 family.
also do you have pics? or a website i can check this out?
