Interesting... Well, needless to say I'll never reach that point!

All CAIs perform within a few HP of each other. Simply testing one on a cold day as opposed to a warm day would be enough to make it beat the other CAI that it had lost to just the day before. There is not much of a difference at all.

Its all in the tune.

Hi ohnoesaz,

Sure, but this is only true when the CAI kitis not the power limiting factor on the engine. Once the CAI kit airflow is the limiting factor the differences in CAI kit airflows will become more obvious on the dyno. For example when you have all of the usual intake bolt-ons, standard CAI kit, 62mm throttle body and CMCV deletes changing CAI's makes no real difference. But when you install a set of hotter cams the higher flowing CAI kits will allow the cams to produce more power than the smaller CAI systems produce. Somefolks have seen this on the dyno when switching between the C&L Street and Racer kits and standard Steeda CAI and the SteedaHigh-Flow Intake Elbow. Brenspeed and JPC have both experienced this with CAI kits. You have to have a need for the part before it willproduce power up to it's potential. This is why the C&L Street CAI is good enough for most people and the Racer looses some power until you add a 62mm throttle body and cams and then the story is reversed with the Racer making significantly more power then the Street CAI kit. It's all about keeping the system balanced from one end to the other or you will not see maximum power gains from a given component.

It's a big tube with an open element air filter. They're all the same. The tune is what wakes the car up. Stay conservative with the MAF opening 88-90mm is plenty. It's a 300hp car. Even the 95mm Racer is within 1-2hp of the street kit.

Having said that, I think the Steeda CAI far and away is the better looking of the two; I just decided to go with a tuner who did not sell it, and Steeda wanted $50 more for the kit than Brenspeed offers it on their website. Yeah, no thanks.

Killer deal! You will like them even more once you get one of Doug's tunes.

I hope Doug's tune will make my car chirp during 1 and 2 shift and 2 and 3 shift. That out of an automatic is rediculous. Supposedly according to my mechanic, he was out driving the car last night with the new underdrive pulleys and the CMCV delete plates and the B ama tune. He was able to pace with a ws-6 that was modded. The longtube headers and x pipe are going on tonight. Hopefully he wasn't kidding!!! Doug's tunes are sick...

I just tried Doug's 91 octane torque tune last night............good Lord!! The difference from stock is astounding.
I've run the 87 Performance and the 91 Performance, and just put a load of 91 in last night to try the 91 Torque. They are all amazing. I normally run 87 Performance for my daily driving.
