Ok I know that I will get barked at for this but what is the difference between AFE and Airaid? I have read all kinds of stuff and can not find any real substantial difference. Maybe I am wrong, anyone? Bueller? http://www.dieselplace.com/forum/smileys/Confused.gif

GMC2500HD,


This is some info from one of our customers and it'e one of the reasons we ONLY sell Pro Guard 7 filters and intakes. If you have any questions etc please call us at the office.


Here's what Dan Montegari of Precision Diesel Services says about advanced FLOW engineering's Pro-GUARD 7 filter media:


HIGH FLOW AIR INTAKE SYSTEMS
WHO IS THE BEST & WHY!


We received many letters asking which high flow air intake system to use. We decided to test a number of manufacturers’ systems to determine which system was superior. We tested each system and found systems manufactured by AFE (Advanced Flow Engineering) were the best by far.


Diesel engines use seven times more air than gasoline engines of equivalent size so clean cool air is a must for extended engine life, better fuel economy and additional power. A higher flow of intake air coupled with a high flow exhaust system allows for more power, a better fuel economy, extended engine life and reduced exhaust temperatures. On the other hand ingested dirt through the air intake system becomes Silicon in the engine oil, which is a harsh cutting agent and can damage your engine quickly.


We tested three very popular systems. I will not mention the names of the other systems as a courtesy but I will explain what problems we found with them. We evaluated the systems by a number of criteria, filtration protection, flow, and design, easy of installation and cost. Almost in the beginning of the tests we realized in most instances a new intake system was necessary to achieve our goals. We needed a kit that used mostly outside air and not hot engine compartment air. We decided to use systems designed to use mostly outside air.


Two manufacturers claimed their systems delivered cleaner air at a higher flow but this was far from the truth. We did not believe any of the manufacturers’ claims and tested each system by operating the vehicle 3,000 miles and performing an engine oil analysis to determine Silicon levels in the engine oil. The vehicle we used has an engine oil analysis performed at every oil change so we had a Silicon number of three (3) to base our tests on.


The first manufacturer’s system was fairly easy to install but we had problems with the oil used to coat the filter also coated the Mass Air Flow Sensor causing a service engine lamp to come on. I called the manufacturer but they had no explanation as to why this should happen but they had this complaint before. Through the three thousand mile test I had to clean the sensor three times to stop the service engine lamp from coming on. When the oil analysis results came back, it was discouraging with Silicon levels at eleven (11). I almost could not believe the result so we changed the oil and filter and repeated the test. The results were almost the same eliminating this manufacturer quickly. I contacted the manufacturer to discuss the results and they were not helpful and basically said, “what you see is what you get”!


We installed the second manufacturer’s system again changing the engine oil and operating the vehicle for three thousand miles. The first problem we encountered was the service engine lamp coming on and I thought the oil they used was coating the sensor again. I removed the sensor and found some oil on it which I cleaned off and reinstalled the sensor. Within ten miles the lamp was on again. I removed the sens

Well thanks for the info, but without names in the manufacturer listings, I have no idea what companies you are talking about and I know there is confidentiality issues but as a consumer I have the right to know. I think AFE makes a good product but I do not want the TUBE they sell with the stage II because of the chipping issues.

Does all the AFE Magnum Force intake systems come with the Pro Guard 7 Intake? Also how long ago was this test?


Thanks!http://www.dieselplace.com/forum/smileys/Big Smile.gif

"I do not want the TUBE they sell with the stage II because of the chipping issues."...........seems to be an isolated incident.......I have had mine for at least 50k miles no issues

Well that is just one chance that I do not want to take. http://www.dieselplace.com/forum/smileys/Confused.gif

I'm still thinking a plastic tube instead of metal for heat sink reasons. I don't want to make the intercooler work any harder!Edited by: Trippin

Ya I have decided to order the Airaid intake kit complete with filter and tube. Should I find a reason and not like the filter then I believe the AFE filter (proguard) will fit.

I think this finish issue with the AFE is so isolated that it is not an issue. My dealer has never had a unit come back for any reason (other than fit, and those issues were easily resolved). But, hey ya gotta do what ya gotta do, but the AFE with ProGard7 filter is tough to beat in my opinion. I have had mine for over 5K miles and no hint of dirt or finish deterioration.

FYI, my AFE tube was one of the bad ones with rust on the inside and it was too long. I called them and they graciously sent me out a new one within a week. The new tube is perfect. I kept the old tube and I'm sending it out to be Jet-Hot coated inside and out and I am going to trim it to fit better. I have a buddy who can get me a deal on this so I think it would be fun to see what I can make of their tubes.


I am running the Stage 7 filter and I love the thing. It is a very nice setup.

I pulled my PRo guard 7 filter off and inspected the tube this past weekend. Tube looked great, wiped down the inside and found no residue, filter seems to be working well. Oil analysis confirms this.


washed and reoiled the filter and reinstalled. Ready for another year of sounding like a kenworth!http://www.dieselplace.com/forum/smileys/Cool.gif


I couldn't be happier with this unit, don't let a very few isoloated problems deter you from this. Even a Rolex has made a few loosers.

I've been running either the old Amsoil filter and lately the K&N drop-in filter in the stock airbox on my '01 which I know is quite restrictive. I know there is a report about a problem with "one" of the tubes on these units, but, hey, that happens to them all. Just ordered the AFE Magnum Force intake with Pro-Guard 7 from Dan @ Xtreme Diesel today.


There are some who recommend other filter setups, and I respect their viewpoint, but most say this seems to be the best unit going for these trucks right now.


Heck, I remember when everyone hated the K&N and then loved the Amsoil drop-in. I was never fond of the Amsoil filter and have run K&N's on everything I've owned for the last 12 years, and never a problem with a vehicle of any type. Back in the mid- 90's the K&N made a nice difference on our 3000GT Turbo, quite noticeable.


Let's see what the AFe does . . .
