Ditching the AFE?

Hey y'all. I've been toying with the idea of ditching this AFE cai that the previous owner installed in favor of a diy setup. I'm tired of screwing around with cleaning this thing and what not, and was thinking I may be able to get a little better air flow out of a 6637 to help clear up some of my black smoke issues. It's a pretty cheap mod to roll the dice on, but I figured I'd see if anyone had any thoughts? Thanks!

I don't know if you'll gat any better flow out of the big Donaldson filter, but it flows pretty darn good. I always hated having to clean the K&Ns (buying the cleaner and oil, cleaning it, waiting for the thing to dry and then reoiling it). With the Tymar setup (or the DIY version), 10 minutes and you're done for at least another year. Cheers!

Thanks you guys. I know the K&N vs 6637 subject has been beaten to death, but I've never really heard any thoughts on the AFE. I think I'll give it a shot! It's too damn cold out to be messing around with washing filters!

i just switched mine, the 6637 makes every bit as much power as my K&N did. im not good at fabrication and custom jobs so its taking me a little bit to figure out just exactly how to run it, right now im using PVC. but you can sell the afe for 150 and get the 6637 mod done for 50 bucks. so you can put fuel in if youre tight at the same time haha

Your not going to see a difference, other than what you physically see. If you have smoke issues then you need different tunes or have a boost/exhaust leak somewhere.

BTW, it is the set-up with the heat shields correct? And what filter is on it?
