K&N Filters

[Altitude]

I have a K&N in the Yaris and in my Jeep. Never once had a problem.

[YarisOwnersDad]

Some of my Jeep buddies were finding dust DOWNSTREAM from their K&Ns in the air tubes. I have heard of other cases like this, also, but I don't personally know those other people.

If a filter is less restrictive to the air passing through it, then one must ask the question, is it still as efficient at trapping the dirt as the conventional paper filter?

If there really might be some slight HP gain or some slight MPG gain, I would still not want to risk using a less efficient filter. From K&Ns own HP comparison graphs, it appears that the extra HP only comes at WOT, and how often are we going to drive like that?

I'll stick with the old fashioned paper filters, thank you.

True, some extreemly fine dust may get past a K&N. What little "dust" that does not get filtered should pose no threat under normal conditions.

However, even though I'm a K&N supporter, I probabably would not install one if I consistantly drove in extreemly dusty, dirty conditions.

So, like many things in life, when installing a K&N, a little common sense goes a long way.

45,000 kl on my '08 sedan with the K&N drop-in since week one and no negitive issues. Many hundreds of thousands of kilometers on past vehicles all with K&N's and they all ran strong and flawlessly. I've saved over a grand in throw-away filter purchases by running K&N.
And by saving the original OEM filter I can use it while I clean, thoroughly dry and re-oil the K&N at a leisurely pace.

all I hear is the sound of an old plane plummeting erratically toward the ground, as this thread has gone south ;d

I think it started with the claims that the Avalon might be a "pace car for NASCAR or on some dirt track" and did the final shark jump with the Bin Laden is hiding in the air box silliness.

You got to admit, those were good.

No, just silly deflections and evasions. Oh well.

How bout a mod close this thread as it is no longer informative and useful

Would you get better airflow by cutting out the carbon trap?
Would it set off a MIL code?
Thanks!

Not for sure. I think the carbon helps soak up any fumes that is in the air that might would eventually set a sensor off or cause air ratios to be off.

the filter increase the driver. makes him to feel good...

Guys,

This really isn't about air filters any more, is it?

I'm probably the only person still following this thread but I think this race is run.
If you like them-use em. If not, accept the fact others can and and they are not inferior beings for using them. I've seen cases where K&N's work well and cases where they were a huge let down based on oil analysis.

I personally don't use them but know others who do-we don't fight about it. Agree to disagree and call it a day.

We know!

Can't believe you basically asked *how high* I wanted you to jump when I said my friend was willing to pay me to keep you bouncing for another week, when you announced that it appears I'll get to spend that $200.00 for sure.

If you weren't so OWNED you would have at least came back with something like: You'll never collect that because you won't last that long

But instead your next follow up was:

"Well I am in the middle of my annual 2 1/2 month vacation and I have nothing better to do at this moment"

WOW!! You're really letting me control your vacation time? PWNED!!

Well at least during the week. Not any good shows on TV. Too hot to play golf. No important professional sports during this time. The wife is at grad school. So you are very entertaining! Some of the things you have come up with make me laugh. Like when you said Wix sells more filters than K&N. Your way of thinking is sooo hilarious!
