Ive noticed a difference in power, and torque and mpgs with my ebay CAI! 38 bucks and it comes with a filter!
When you say power and torque do you just mean how it feels like as in low end.. or are you talking about responsiveness and/or faster acceleration?
what about low output.. normal driving acceleration.. and WOT acceleration. these are the things that matter most to me.
Most people in these trucks want better acceleration... some want it in stomping in the gas.. others like me just want better acceleration while driving normally.. better response out of the engine.
It would really give a better insight for those looking to do this rather they actually want to spend the time and money if they had these details.
A CAI alone won't yield you very much, plain and simple. Where the CAI really comes into play is when you put on a less restrictive exhaust and start messing with cams and stuff. Just a CAI will maybe get you 1mpg increase. It should help a little with responsiveness though. Nothing like throw you in the seat difference but if you want that swap in some 4.56 gears.
I agree with MoparMan1991 in that you need to open up both ends of the engine to get any improvement in hp or mileage. As much as anything, I liked how the CAI cleaned up my engine compartment.
I agree as well. I also installed a 49(I think)mm ported throttle body. I also had the shop install a cherrybomb turbo muffler. It's a cheap $20-something muffler that makes a good OEM replacement.
Only thing I would worry about with doing that is way too much air pressure with it getting direct air like that now if you could make some kind of air pass-through like some kind of tube that would let air in the front and then out the back thus no high air pressure and then the throttle body feeding off of this air passage.
My Dak being the 2.5 dosent have any exaust on that side of the engine
