I am not sure how a air intake test for a 3rd gen relates to a 2nd gen owner but it was something to read. The 3rd gen trucks and a much less restrictive factory air intake system than the 2nd gen rides and almost anything will outflow and outperform it.
I took all the ones that I had here at one time to my local dyno shop when I was doing some testing to try and find the one that I liked the best and search for any differences. At the time I had a AEM Workhorse with their dry filter,AFE Stages 1 & 2,K&N,S&B and the TDR Favorite BHAF/Mallory Mount. In order of performance back then was the 1-AFE Stage 2,2-AFE Stage 1(I also had their newly design torque tube which had just came out back then),3-the BHAF/Mallory Mount,4-K&N system,5-S & B,6-AEM Workhorse. There was a 12hp difference from best to worst and 7hp difference from the AFE Stage 2 to the AFE Stage 1. That day I was very impressed with the old TDR favorite BHAF/Mallory mount as it was only off 8hp when ran in the same conditions as the AFE. The absolute worst was the AEM Workhorse and that was a shame to me as it was the best looking but at 18hp less than the AFE it was sent down the road to a new owner.
I ended up with the AFE Stage 2 and now have almost 200k on the intake system and two filters I have. All of my other systems were sent to new owners at various shows I went to that year and the only other one I kept was my BHAF/Stainless Mallory Mount and that was because it was one of my first mods after joining the TDR.
As for how underhood heat affects the air intakes there was a very extensive test done by Gary with real world towing data that showed little or no difference in intake air temps while moving and only slight increases when sitting at a traffic light. IMO after seeing his post way back when it convinced me that there is enough air flow to not even make this a area that should worry anyone,unless you have a compromised charge air system.
So,until S&B or AirRaid can show me strapped on my local dyno that their intakes/air filters can out perform my old trusty AFE Stage 2,I will keep using it and plugging the product as it really is IMO the best for our truck available. For those who require a "Dry" filter for the intake I use,that is also available... ... Just My . 02 worth... ..... Andy
