Air filter - Fram CA10544 extra guard

Sh0velMan

To say nothing of the fact that OEMs changed to paper air filters because it lowers maintenance costs and reduces warranty claims, when you're comparing a paper filter to the oiled filters of yesteryear... Which have very little in common with a K&N or the like.

Point is, does going to an oil filter lower the life expectancy as compared to a super thick 'Extra Guard' style paper filter? I feel comfortable saying "yes".

It probably does lower it, from around ~300K miles before the rings are gone to around ~225-250K miles before the rings are gone.

I could not care less about that difference, and I don't think anyone driving a Z today would or should, unless you really care that much about the next owner (or the one after them, or the one after them)...

Besides, the oil pump, VVEL system or rod bearings will probably go before the rings do. Just sayin.

This could be talked to death.

Bottom line:

Want a handful of horsepower? Buy K&N or the like.

Want an engine you can tell yourself will last longer and don't care about horsepower? Buy the thickest damned paper filter you can find.

Everyone's happy!
