Bubba, you should get a used oil analysis and see how much dirt is in your oil. I ran several oil analysis on my 1st Gen to establich the change intervals after I first got it with a K&N filter installed by the PO. Silicon slowly rose higher and higher over a two year period, until wear metals followed, indicating accelerated engine wear.

You can probably just subtract the 200k miles off the end of your engine life.

Sorry, as to the K&N I should clarify that Im talking about the K&N brick filter that fits in the oem filter housing. The K&N does flow very good but I clearly had visible holes in the filter media - Im thinking that would let a lot of dirt in. Maybe my filter was defective? - I dont know. I have not used a K&N cone filter so I cant comment on that.

Not sure I would be as bold to say that using a K&N will cut 200k off your engine life.

Like I said: "probably." What are the real numbers over the life of an engine? Who knows. Wear is wear. Will it manifest with ever increasing blowby from losing the rings? Or will it let go suddenly after a rod starts knocking? Who knows.

What's your acceptable engine wear comfort zone?

later instead of sooner...lol

My oil is changed often! This truck has been my pride and joy for years and my wife said she will bury me in it. My son said hell no! that's a a waste of a good truck.My filter may not be a BHAF but it does seem to get the job done. I do agree that more air in equals better performance

K&N filters.
