Why would I do that when I clearly said there has been nothing to show K&N filters lead to shorter engine life? Again, you clearly cannot read very well.

Then why are you saying they're lousy filters? If they actually were lousy, then showing evidence of excessive engine wear would be easy...

Because there isn't a worse filter out there when it comes to...you know...filtering air entering the engine. Being the worst makes it terrible. Not sure why this is so confusing for you.

Here's someone's study on K&N and other filters

I think grampi's point is, if engine life isn't effectively worsened, then how much does it really matter? Say Person A uses the best filter out there and gets 300k miles out of his engine. And say Person B uses the worst filter out there and gets 300k miles out of his engine. In the end, what's the difference?

You want the best filter, right, to keep the most dirt out of the engine, right, so the engine will last longer, right? The very last factor is key..."so the engine will last longer". We use air filters to keep dirt out of the engine....and the ONLY reason is to extend the life of the engine. There's no national contest out there for those whose cylinder walls have the fewest scratches. Sure, you can measure dirt that a filter passes, and it might make you feel better to know that Filter A traps more than Filter B, but it's an argument of conjecture until someone can demonstrate that engine life is affected.

I suppose one can draw a parallel with engine oil here. An oil's main purpose in life is to lubricate the engine right? So why not buy the oil that does that the absolute best. You're using conventional Valvoline. A lot of other oils out there pass much higher performance standards. Why do you use Valvoline? Because it's sufficient, right? It's sufficient for the task.

And there's a direct parallel with oil filters. Some people believe that the only filter that belongs on a car is one with 99.9% efficiency at so many microns. And they're free to use those. Meanwhile, Honda and Toyota are using oil filters that are 60% efficient and, yet, their engines last just as long, if not longer, than anyone else's. The 60% efficient oil filters are sufficient for the task.

It could just be that K&N filters are sufficient for the task. Until there's a lot of evidence to the contrary, I'm afraid all discussion is only conjecture.

You apparently missed the two previous posts of mine where I made that quite clear. There is little hard evidence showing K&N reduces engine life by a significant amount.

On the other hand, it is logical to assume dirt in your eninge isn't a good thing for engine life.

It sounds like SAE does have some studies showing poor filtration increases engine wear.

I didn't miss them. I think there's simply a difference in perspective among us. A filter that doesn't filter as well as another makes it a poorer filter. It doesn't necessarily make it a poor choice for use on a vehicle.

I'll bet there are tires out there that perform better than the ones on your car. That doesn't make your tires terrible. There are probably shoes that are more comfortable than the ones you're wearing. That doesn't make your shoes terrible. There's lunch that's likely more tasty than the one you'll have today. That doesn't make your lunch terrible. There are tradeoffs in everything. A theoretical loss in filtration of a performance filter might not affect the OP's engine life at all, and he gained a better knowledge of how his car works and probably a better appreciation for the way his engine bay was designed and packaged by installing the filter kit.

If they are the worst at doing their intended job, then they are terrible. Terrible is a relative term.

You're wasting your time...it's obvious badtlc would rather argue about semantics than discuss facts...
