I just installed mine. I feel better about this filter than the K&N. I think dirt does get through. At least on mine it was. The filter does get pretty warm that close to the turbo. I pulled my trailer home from work today, about twenty five miles, had it running pretty hot. As soon as I stopped, I hopped out and checked the filter to see how hot it got. I could almost, but not quite hold my hand on the closest part near the turbo, the black end cap was getting hotter than the metal mesh. Anyway, I am looking forward to more feedback from everyone else on the longer term use of this filter. Thanks Moparguy.
