Mino Don't worry about the K&N I have had an open intake K&N on both my diesels and I used to run around in the sand alot and I put 150,000 on my 95 with one on and I have 120,000 on this truck and never had a turbo problem just get an outerwear for the filter then all you have to do is clean the outerwear and the actual filter prety much stays clean.
