high-flow filter or CAI...

everyone talks about how great the CAI is w/o any real proof it adds any performance gains. Sure they sound cool, but is it $300+ cool? If a high flow filter will provide the same responsiveness as the CAI wouldnt this be the best way to go and spend the money saved on something else? I need help on this decision.

Re: high-flow filter or CAI...

I have the money for the TRD CAI, but I need to know if there truely is a performance enhancement? Is 5hp and 10lbs of torque worth $350? If i can get the same responsiveness with a high-flow filter @ $70, it would make sense to do so. Or better yet, buy the filter and an exhaust. But then, I have heard lowend torque is sacrificed with a new flowmaster or magnaflow setup. there are so many topics on this subject, yet nothing that really tells me anything other than 'it sure sounds cool'... and 'I can feel a difference.' I feel a difference in performance when I get my oil changed, but I know it didnt do anything for the performance, per say.

Re: high-flow filter or CAI...

went with K&N and Daystar leveling kit. 38 for the filter, 157 for the leveling kit. this leaves me with 125 to spare.

Re: high-flow filter or CAI...

The stock intake is a cold air intake. The air enters the intake from under the right front wheel well. The advantage that the aftermarket CAI's provide, if any, is higher flow through the filter, either because of the material or they have increased surface area. In fact some of the designs seem like they are likely to have higher intake temperatures.

I like the way you think.
What exactly does the leveling kit do and how is it different than autosprings?

Re: high-flow filter or CAI...

yeah, the stock setup is a cold air intake. But, the tubing is tiny with a lot of bends. Also, you have a huuuuge baffle that covers the entire engine. That just SCREAMS restriction. Once I saw that baffle, I knew, without a doubt, that ANYTHING is better than the stock intake.

The TRD/AFE intake sucks air from the same spot as stock, so its still getting cold air. The major difference is that its a straight shot directly to the throttle body with almost no resistance.

No, I don't have dyno numbers, but trust me...theres a nice gain from the AFE CAI that I bought.

Think twice about Doug Thorley Long Tubes.

Re: high-flow filter or CAI...

I went with the K&N filter because I knew if I got a AFE CAI my foot would be stuck to the floor so I could hear that great sound. That would RUIN my gas mileage.

It's more or less a spacer kit. It gives the right amount of clearance for 33's, and reduces the front end sag. Not familiar with autosprings. I think the rest of the cash is going towards an auxiliary light kit.
