I've been a fan of AFE products for years. I ran the afe cai on my last truck and have been running the cold air intake setup on my current truck since 2008. I also have the 4" Stainless Steel Mach Force Exhaust system from AFE. I thought I would share a little of my current experience with the forum, and am even including some pics.

Ok- so went in this week to do my spring oil change / fuel filter / clean the AFE routine and saw this:



and this:



These have been installed for roughly 5 years. So of course, they are past the 2 year warranty from AFE (I called and this is what I was told). So now it's up to me to buy a new "lifetime" filter and the rubber coupler. What miff's me about this is that this type of degradation of rubber is something I'm more used to seeing in a vehicle that's 20+ years old, not 5. Granted this stuff has about 80K miles on it in those 5 years. Still- it's not holding up well in my opinion, and the forum members should see that. Even if I got a *bad* one, AFE isn't covering it under warranty. I now have to decide whether to pay for more AFE stuff or go somewhere else with my money.

To throw a little salt on my wounds, I put the truck up on the neighbors lift to install my new FTE Resonator (The AFE Mach Force exhaust drones pretty good over 2000rpms). The 8 month old exhaust looks horrible. Yes I live on a dirt road and I'm in Minnesota. They don't salt my road, but I've put about 8K miles on this exhaust now, including winter driving in places where the roads are salted. Still, after one winter (with regular under carriage washes- because I love my truck), the Stainless Steel exhaust looks as bad as the drive shaft that has been through 6 Minnesota Winters. I can only hope apparently that it will last the 5 MN Winters (and 1 Wyoming Winter) that the factory exhaust lasted. When I purchased it, I assumed I'd get more than that. Here's what the muffler looks like now (and you can see the short pipe I pulled to put the resonator in place of in the background)



And the longer pipe next to the rear drive shaft for comparison.



As for the FTE Resonator- so far so good. I'm loving the fact that the drone is gone and yet the growl from the AFE is still mostly present. I did install the resonator directly in front of the muffler- so I had assumed (correctly this time) some of the growl would be taken up by that placement, but it was the easiest place to install in the exhaust- I didn't need to modify any hangers or purchase any additional clamps.

So if anybody else has been running a Cold Air Intake for a number of years in a climate that ranges 100+ degrees in temperature, I'd like to know if things are holding up or not. I'm pretty open to suggestions since it's obvious I'm going to have to spend some more money now.

 

the afe intake is a pos engine damaging labor intense mpg robing filter. I can not believe the number of suckers that bought into this. the box lets in hot expanded air reducing turbo efficiency, the filter reduces engine life by 70% compared to stock. the filter holds a fraction of dirt compared to stock before servicing. the stock tube has straightening vanes in the elbow, they along with the silencer ring reduce side shear in the compressor side of the turbo giving higher turbo efficiency and several more bad things with the afe. get a stock box and tube from a 6.7 and add a psm kit.

 

Thanks for the info Carl- though I do see that PSM was using a PG7 filter in their tests. I want to stay away from AFE now that I see their quality has lapsed.

I read a bunch more posts on the forum here over the last 24 hours and I've actually seen a lot from you regarding the stock 6.7 air box. I love the idea of quieter- I never cared for the turbo whine, and honestly, if I'm going to spend $80+ cleaning kits every 5 years on filters I might as well run drop ins that out perform the PG7.

What I'm wondering now is, since I kept my stock air box (because I like having all my factory equipment around just in case something like this occurs), can I use the 53034249aa or Wix/Napa equivalent in my 5.9 box and just mod it with the PSM air intake and cool hose to get true cold air?

Also, if you have been running the PSM stuff for awhile, how is the rubber holding up?

 

just put the stock box back on.....

 

I have already done that- but the throttle response just isn't the same. I haven't run a full tank back on the stock box yet either, but I did see a minor gain in mpg when I put the AFE on. Of course, my truck is broken in now. It may be much different at 105K vs. the 25K that were on it when I put the AFE on.

It feels restricted now in comparison- but I haven't gotten the new filter yet- I still had my old factory filter which had, of course, just been replaced when I got the AFE.

by the way Verdesardog-, I clicked your link, that is one beautiful truck.

 

I think your butt-dyno is fooling you.

Unless you're making upwards of 450hp or so (might be even more), there's no restriction in the factory airbox, that's why everyone is saying to put the stocker back on.
I'm not sure how you're feeling different response to the accelerator pedal...?

 

The 4" Napa/Wix stock filter flows way better than the 2" you've got. The filterminder won't move especially if you do the www.psmdiesel.com mod or Home Depot version. I shortened my downpipe a bit in order to raise it up. Works killer.

 

Thanks, I like it!

 

I did not figure you kept the stock box. danderson is correct, use the 4" filter, the 6.7 box only flows about 7% more air than the 5.9 four inch filter. we installed several psm kits in 2005-2006 time and all are in perfect condition. and pronstar is correct on dyno.

 

I have the Wix on order- cheaper by $10 to order online than at the parts store, so I have two coming.

My truck does make over 450hp with the chip turned up- but it doesn't seem to make a difference whether I'm on 1 or 5 (Edge Juice), I still feel a lag in the throttle (slower spool-up). The RPMs simply aren't as responsive to the pedal as they were. I've owned the truck it's entire life- I bought it new in 2006 with 15 miles on it. Nearly 7 years and 105k+ miles later, I know how this truck feels. I don't think my butt-dyno is wrong, but certainly anything is possible.

Thanks for the advice- I'm going to start with the 4" filter and the PSM "cool hose" to the turbo. I will add the downpipe for more cold air if this doesn't get me back to what it used to feel like.

 

I don't see a signature,but EFI programmers are supposed to smooth out the power a bunch on the '06-07's. I noticed the uneven power delivery in mine compared to my '98.5. Smarty helps a bunch but it's still not linear
