I have a magnum force kit on my 24valve. Love it to death, I would definately buy another one. The only downside to these filters is the turbo noise. I love the noise myself, but some (girlfriend) and a few others find it annoying. I have my silencer ring out as well. My dad has a Scotty II. I think its probably every bit as good as mine, more than likely better with the cowl hole but the noise it makes with the cowl hole cut is a lot more harsh than my afe. He runs it in hush mode most of the time except for when towing. With a stock truck such as yours I dont know what difference you may feel performance wise, but if you have guages you see a drop in EGT. I did for sure. Someone did a test between the two filters. Run a search and youll find more info than you can imagine. Hope this helps.
