Just put my new air filter on and am very pleased with the product. The exhaust temps are noticeably lower when I am "on it". Before I had to lift at approx 2600 rpm because temps were going 1500+. Now I can get there at about 1200. Will be towing my 13. 5K pound fifth wheel this weekend to Reno over Donner summit so will know for sure how good it helps the exhaust temps. Also picked up 2 pounds of boost pressure with the new filter. My stock clean filter was being dragged down to over 65% on the meter minder.
