Modified my air box and ran it out on the same field same track same distance with the same clutching. Thanks Turk on the clutching you are truly a magician with clutching I spanked a sled that previously was spanking me . Ran with K&Ns on nice and dry and with my modified air box. What I found is virtually the same performance without the louder noise the K&Ns made. Ran all day yesterday with no problems of the air box freezing off like I was having with the K&N's. Will post more info once I test some more.
