Just to clarify, I would not suggest any one use the Accel or K&N filter with out the added protection of the outerwear filter. I am going to run this way as the cool blue is a prefilter and I will keep my unifilter in the box as the "real" protection against dirt getting in my engine.
After re-reading my post and Redriders. I have to say his statment is correct, do you own research, make your own decision on what to run, after all if dirt gets in your engine, youre going to pay to have it repaired, not the guys on this board.
