K&N Air filter questions

[bearda]

I used to run K&N filters until I started seeing UOA results come back with dramatically higher Silicon counts. 1stToyota is right about the amount of dirt making it through the K&N filters compared to the OEM paper one. When it comes down to it, I'd rather pay for the disposable filter than have a bunch of sand in my engine.

Hmm I put 5k miles a year tops on my car. Thus a car with 90k miles on it (for me) means 18 years of use.

i have k&n drop-in's in both of my cars....i take a look at them once a year to make sure they're not filthy.

if find the oiled filter grabs fine particles

saves lots of dough over the long run too....50$ on a drop in is made up after 2 or 3 regular paper filter changes....

Agreed. If UOAs are proving that the oiled filter isn't doing as good of a job at keeping debris out of the motor then being frugal isn't too important if it comes with the inferior filtering trade-off.

I'm sorry but, I fail to see in your link where is says a non TRD part can void a warranty.
Fist off, that woul be illegal (at least in the US) unless Toyota can prove that it caused a particular problem that you claim is a warranty issue.
The same would be true for any after market part.

As far as a K&N filter, since Toyota also sells the exact same kind of filter, they can't legally claim it caused a problem.

:sigh: I never said that, link never stated that. It's not the TRD part that can void the warranty of the TRD part and/or the vehicle, it's the installer of that TRD part that can void the warrantry of that TRD part and/or the vehicle...guess Toyota doesn't want to trust their performance parts in the hands of a DIY project

That's what I said and that's what the provided TRD warranty link states.

I've had K&N filters in almost every one of my cars since 1996 (that would be nine cars) and have never had an issue with any of them.

The same could be said for any part TRD or otherwise from a winshild wiper to a turbo. If a bad install of a part causs a problem, the warranty issue pertaining to (and only to) to that partular problem may no be honered.
The key word here is "can" void a warranty not "will" void it.

However, Tyota must prove that a bad install cause a partucular problem.
Also, an owner is allowed to install a non Toyota part.

At 90k miles Im buying a new car. I just dont see the cost/benefit being in the KNs favor. Maybe if I lived in Alaska on a dirt road and serviced the AF every 5k miles.

So you think you are still getting 99% at 90,000 miles? My guess is that it would be 50% or lower. By then I could have already cleaned my K&N(several times) and still have it 95% or more.

50% would be high I think, and I have my doubts a paper filter would last 90,000 without just falling apart. Mine was filthy to the point you couldn't clean it without destroying it at 15k. If by some miracle it lasts 90,000 miles, there's no way it is going to last 18 years that its supposedly going to take to get to 90,000. I would bet a paper filter sitting in your garage wouldn't work after 18 years just from humidity in the air.

Don't get excited. TRD came up with their warranty claim and how they can choose to handle the situation involving the warranty with the part and/or vehicle in any way they choose fit, when it comes to the TRD part being installed by a non-authorized Toyota/Scion dealer...they wrote their fine print, I didn't

[RedRide]

LOL One of us is getting excited and it isn't me.

I still fail to see what all this has to do with the OP's question about a K&N filter.
A filter is consider a wear item and is as such, is not warranted. except for defects in maufactruring.
The fact that Toyota sells a copy of a K&N filter (it may even be made by K&N) prevent them from claiming that a K&N is flawed technology.

Besides, people have been chaging their own air filters for many decades (including K&N)and I never heard a warranty issue being denied bucause if it.

No, this just got a little too involved because you couldn't understand what you were reading in the TRD warranty claim. The reason I mentioned TRD warranty, and how TRD reserves the right to void their warranty on the TRD part [you're pretending that oiled filters are "wear items" that don't have a warranty?] and/or the vehicle warranty is because you chose to use the ol' Toyota TRD crutch that K&N has to be great because Toyota sells TRD parts...just thought it was time to mention that, yes, Toyota is so proud of their TRD filters, so long as they do the install, but if it's a DIY project they can renege on their filter warranty, and void your vehicle's warranty while they're at it, if they're in the mood.

You may have never heard of it, but it's still listed on their TRD warranty claim.

The best part of K&N's is not continually throwing $20 plus dollar filters in the trash.

And certainly not enough of a sense of humor. Think about what you are going to miss if you leave:


Arguments over misinformation in air filters, oil filters, cabin filers, fish tank filters

Whining over the inaccuracy of gas gauges and filling up until the first click or until it sprays out

Complaining about only getting 39.987678 mpg when driving uphill at 45mph on Wednesdays

Being surprised when parts off of EBay not only don't fit but just plain suck

Questions on why their cars erupts into smoke and flame whenever they try to use said EBay parts (usually electrical)

Discussions on 13" wheels, because looking like your car is on skateboard wheels is trick

Politics, the lack thereof or excess in

Shifting an automatic, because bipolars need love too

Tales of people paying $10000 for used Yarii with 500,000 miles and wondering if its a good deal after the purchase

Not to mention the tutorials, pictures, funny stories, feedback from knowledgeable members, open discussions where no one gets their posts deleted, honest recommendations and reviews, and the hidden pictures of women with barely a stitch of clothing on showing you their gymnastics routines.


So I can understand if it seems a bit overwhelming, but really where are you going to go? The SVT Focus forum has been dead lately, so has the Yugo Enthusiast site. Drink your morning coffee, have a buttered croissant and come on back to YarisWorld... make sure you have your sexy underwear on, we're classy people here...
