K&N Air Filters Destroy Diesel Engines!!!!
...is what my local Ford Dealership Service Dept. advisor told me today. He said that they have had two PSDs with only 25,000 miles on them that were destroyed by K&N air filters. He further mentioned that K&N have discontinued their diesel air filters because they are so bad. AND, he said that if the engine gets hurt the warranty is voided since you aren't using the factory filters.
IS THIS BS? Sounds like it to me, but then again, I figure the good folks here can provide me with a bit more *accurate* information.
I love my K&N filter, and have had no problems thus far. I think this guy is just trying to scare me or something. What about his three claims (destroys engines, has been discontinued, and is not covered by warranty)...can anyone give proof to this?
