Air Filter Question - Toyota Yaris Forums

willyt · 11-10-2008, 11:32 PM

If I upgrade to a K&N or such, will the computer just account for the more air and add more fuel etc.? Or will it "trick" the computer?

Appalachian Trail 2007 · 11-10-2008, 11:34 PM

it won't trick the computer...a lot of studies have been done by users at ecomodder.com but they found that it won't have any real fuel savings

willyt · 11-10-2008, 11:35 PM

Ok. Is there any advantage, then, to having a more free-flowing filter?

Appalachian Trail 2007 · 11-10-2008, 11:40 PM

I couldn't find any when I was researching it. Other than of course the re-usability of the filter (which is worth the price)

willyt · 11-10-2008, 11:42 PM

Ok thanks!

Appalachian Trail 2007 · 11-10-2008, 11:45 PM

not a problem, goodluck

I have a K&N in both of my Yaris's and they are great!

MadMax · 11-11-2008, 10:07 AM

Just to toss in a second consideration, K&N air filters are shunned in the Jeep community due to tests that show that they do not filter as well as some other filters (to include the stock one). That is more of an issue with offroad vehicles, but I had one on my 96 Passat VR6 and it did eat through a couple of MAFs due to its weaker filtering ability. However, it did add power to the car (or at least it felt and sounded like it did!). Just be aware that if you use an open CAI filter and live in a dusty climate, you may want to maintain it more often than recommended!

Cheers! M2

Waste of money IMO. The MAF meter will probably just readjust for the extra airflow, plus I made one Avalon customer real mad (at his new K&N filter) when he came in because of a code being set soon after he installed a K&N drop-in. MAF meter was gunked with oil and calculated engine load wouldn't get much over 60% @ WOT, cleaned the oil off the MAF, installed a Wix filter, test drove again and saw an over 80% reading @ WOT.

One of the meekest and kindest looking troll threads I've ever seen.

-1 on the K&N. More minuses than pluses. Just change your Factory filter 2X a year or if it gets wet. You will see and giant increase of wear materials in a UOA and can easily gunk up a MAF with the K&N. BTW there is no "tricking " the MAF. Thats is whats it is there to do - measure air flow. If you have more air flow it will measure it. Likely only at the TOP of second or 3rd gear at over 5500 rpm. Not a place to stay for more than a 1/2 second. Total WASTE. I would work on getting cold air into the stock air box. This car gets weak kneed in the summer. Yari have worst cold ail inlet location I've seen lately.

Ran a K&N in my previous vehicle, 1995 Talon TSE AWD. Likely cleaned the open element filter less often than I could have. Drove that Talon past 280,000 kl (~175,000 miles) without any MAF issues and it never consumed more than a litre of oil over my 5000 kl change interval so the internals couldn't have been seeing much wear from grit.
I used K&N on the car before it and now in my Yaris. Not changing what isn't broken and saving hundreds on disposible filters to boot.

Soon as I see Amsoil come out with one of their 100K reusable paper air filters I'll be gettin' me one of those. Won't have to worry about over oiling it (and it will coat the MAF with oil), or undertreating it, letting grit get into the motor.

Thats kind of funny because my 05 Tacoma came with a K&N filter already in it.
