Default "Best" CAI??

This might be a stupid question, or just based more on personal preference but from all of your experiences is there any one intake for our trucks (K&N, AFE, Volant, AES, BFI) that are any significantly better than the others?

I have heard the BFI is really good, but its a long wait and pricey, and I've heard that since its metal it heats up and in turn heats the air going into the engine (the air is moving so fast idk if this even makes a difference)

I have also heard good things about the basic K&N filers as well as AES filers.

Basically What I'm looking for is maximum air into my engine and get that roar going as well as trying to get some better MPG in the process, although that isnt as important to me I'm planning on getting a cat-back system and Diablo with this set up all at once in a few weeks, so any input would be awesome!

You are opening a big can of worms here. Any who - I have always come back to Volant and then still made minor adjustments. On the Dodge I took the Volant and added an Airaid Jr (which I moded) so that I could remove the resignator completely and go direct to the throttle body. I also have the ram air tube for it on the way so that will be another minor gain, but with all that said and the parts used I am over $500 for my set up. Thought about the BFI and the Vararam but I like the Volant since there is absolutely the least amount of engine heat transfer going back into my engine when the concept is COLD air intake. My 0-60 time is impressive and with a few more small components I hope to be at 6 seconds which is great for a Quad. Just find the deal that suits your budget and go for it. Keeping in mind that almost anything is better than OEM with no mod and the engine can't breathe. CAI, Exhaust, and a Tuner = enjoy the ride.

Most of the CAI's do the same thing and give you mostly the same results.

I prefer the closed systems, such as Volant or AFE, but have also run the open filter type to good effect.

Really, it almost boils down to what looks good to you.

true, you will get many, many different opinions on this subject...the only thing we can agree on is that an aftermarket cai will outperform stock...after that, the term "best" is subjective... are you lookin for best absolute performance, best aesthetics, best fit an finish? Altho most will say the the difference between any aftermarket cai is minimal performancewise, I do feel that a couple of them are top tier based on performance on tracks as opposed to dyno testing (which are always skewed by the high dollar companies to have you believe their is superior)... the bfi and vararam are on more of the fastest (at least in qc's) trucks then any other.. over the years I've done a 4" homemade setup, a mopar clone and a bfi...each one better performing then it's predecessor with the bfi (ramhammer when I first got it) standing head an shoulders above..an not by a little either. It also comes down on how you mod as well..I did cam and heads which demands the absolute best in airflow (but is also beneficial on lightly modded applications as well)...

Yes its a very hard decision indeed... I was looking at the BFI, it just looks so badass and the filter is huge, and i like the position of it, seems like it would get a lot of air forced into the filter...

On the other hand some closed systems provide the same type of thing with a more angled air intake... I figured they were all relatively the same, but like yall said I think its also more personal preference.

And on another note the last time I looked @ the BFI it was 400 bucks now its only 330

Oh one other thing I wanted to ask anyone here if they had a BFI, since the tube on the BFI is metal, would i run into any problems with it getting hot enough to actually heat up the air somewhat before it enters the manifold? I think it wouldnt get too hot and even if it was hot the air is moving too fast for it to make a difference, but just thought I'd ask

IMHO the air speed is too fast to get enough convective heating to be a real problem.

id go with a K&N there the best bang for there buck only around $400 but if you get a cai your best to put a tbs in to. your just not going to be able to get that good air flow without it. but thats what i would do
