    Please quantify those differences. Can we get some hard numbers so that we can supply this man with some cold, hard facts rather than seat-of-the-pants subjectivity? I'm asking because as I understand it the performance gains associated with CAI's only manifest themselves (in significant enough fashion to be human noticeable) at WOT (wide open throttle) ... and the numbers I have suppport that understanding.

    With a stock air box I saw temperatures that were ~3 degrees higher than with my Outlaw CAI. This is as-measured in a 20 minute data log (for each run) with the engine at normal operating temperatures prior to the start of the logging. I'm sorry to say but a ~3 degree temperature delta is not enough to make a substantive difference in the course of normal driving -- and definitely not enough of a difference to be human noticeable. It -can- help generate a few ponies at WOT when the engine is gulping as much air as possible, as it's a little added density ... but that's about it.

    Are you sure subjectivity didn't skew your observations? People sink money into CAI's ... so of -course- they expect a difference ... and tend to make observations based on their expectations. It's human nature. If you've got some data let's see it, as I'm always up for learning something new.

    I can't remember where I saw this but after I bought my Volant CAI I found a graph that showed the difference between a full K&N system, K&N drop in filter, and another brand of CAI (might have been a Spectre kit but I don't remember). The info that was provided showed that the largest gain was actually with a drop in filter with a large hole drilled into the bottom of the air box. I paid something like $350 or so for the Volant, a K&N kit is about that also. While a drop in filter is something like $60 or so. With all that being said I like the look under the hood of my truck with the Volant kit. The straight tube that replaces that stock piece cleans up the looks of the engine compartment.

    yep. i just did the K&N drop in filter. didnt feel like spending the bucks to get a full CAI. maybe down the road i will get one.

    Surreal, you make very good points as usual. And no I don't have cold hard facts. But I do know that there is a difference from stock. Yes the difference is only really noticed aat a hard acceleration, I won't even call it wide open. But it does accelerate easier and reaches the govrnor with alot more pedal to go. Almost gets ther before it hits six gear which it didn't do before. Yes I would agree that it doesn't save the kind of gas that is advertised but I could see it saving on long interstate trips. And yes that is purely speculation. It also sounds a little meaner. And I do love the way it looks in the engine bay. And for those reasons alone the money was worth it for me. I did not notice these things with a K&N drop-in on past vehicles. But perhaps had I drilled a big hole in the bottom, like aloxdaddy99 stated was done in the graph of data he seen, then maybe I would have notice similiar rusults.

    Now this is just my opinion. But I think you too will noticed a difference. My truck does accelerate faster and sounds better doing it. And yeah it's your choose. But there are three performnca mods I plan on doing without getting into big money and drastic engine work. Here they are in order of instalation exhaust, cold air intake, and Diablo programmer with a Diablew tuning. Diablew tuning is a custome tune specific to your truck done by Lew a member on here know as 06MonteSS. Contact him and consult with him. I personally found his info very helpful. But between the combo of the three in my opinion you can't go wrong. I've done two of the three steps and as soon as the budget allows I will be getting the Diablo Trinity. You have to decide for yourself but I wouldn't recommend someone do something that I regreted. Good luck in making your mod decisions.
