No one has mentioned this but it is a proven fact. The oil from the filter will coat the little fine wire sensors in the MAF sensor just down stream from the filter and then the dust will stick to them and insulate them from the air flow. This gives the computer the signal that there is very little air flow going past them and thus, leans out the mixture, sometimes even to the point of sluggish to no acceleration and backfiring from lean mixture. Put it to the floor and you will go no where. Slow acceleration and you may not even notice it but on a '99 Sub (350 Vortec) in low range 4wd, on the gravel, will not even spin the tires when put to the floor. My advice to anyone using an oiled filter is to take it apart and spray the MAF wires once every 6 months. Bets to leave the K&N to the racers who will rebuild every year anyway.

At one time I had seven restored examples which were shown and used in ploughing matches. As most restorers, I have a number of war stories I can relate on a range of topics that may help other like minded and interested people. Perhaps my first p
