HighlanderGeneral discussion forum for the Toyota Highlander and Highlander Hybrid.
This is a discussion thread titled "Good aftermarket air filters?", within the Highlander forum, part of the SUV Forums category.
I'd suggest K&N. After a 2 or 3 month break-in period, your gas mileage should start to improve (at least it did with my truck).
I bought my Highlander with 7 miles on the ODO. I had put it in my garage for almost 5 months and it now has 34 miles on it.
I guess yu say it is broke in now?
My gas mileage didn't get better!! what gives?
Should I wait for 2-3 more months to let it breakin more.
Acording to yu, I'm afraid to drive the H/L and waste gas with bad MPG until more TIME has passed. Everyone else told me breakin occurs with use. Now I'm VERY confused!!!!

I'm not sure how you got the idea from my posting that the vehicle needs to sit for the break-in period. To clarify, after 2-3 months of having the filter in the vehicle and DRIVING the vehicle, the gas mileage started to go up in my truck. You need to DRIVE the vehicle to break-in the air filter.
K&N's are great for race cars, but don't do a good enough job at removing fine dusts/dirt... Also, the K&N I used to run on my T100 worked great for about the first 1000 miles, then performance started to drop off dramatically. Cleaning (which is a pain in the A$$) improved the performance, but who wants to clean their air filter every 1000 miles for only minimal improvement.
After trying about every product on the mkt (including Bosch, Amsoil, etc.), I've switched all my vehicles back to OEM Toyota filters.... and I think my engines luv me for it.
6 cyl Highlander
Looked at fram- very thin sealing area gasket
looked at purolater- no sealing gasket just filter media
whats a good filter?
Most studies have shown a K&N or similiar filters only provide benefits at WOT (Wide Open Throttle). Also a clean (read this as new) stock airfilter provided the same gains as the performance K&N. It is also true that they let more dirt particles than a stock filter and if oiled to much, or incorrectly, can cause damage to your MAF (mass air flow) sensor.
I used to use them and never noticed any big gains that would offset the initial cost. After reading the studies I saved my money and just changed the stock one annually.

Oh by the way, "Batteries are included" with the Prius & Highlander Hybrids
I've run stock, K&N, and Wix on my Tundra. I prefer WIX and change every 10k or so. I noticed more torque (compared to K&N). I don't think there's anything wrong with the OEM filters, just change them regularly like any other filter.
I run a K&N in mine, and have better gas mileage ever since, over 10,000 miles now. Of course this winter it's dropped back down (but that's more due to my foot constantly on the floor, and the Highlander beeping at me as I go sideways.)
The biggest thing that gets people on the K&N, they feel that more power, and start pushing that throttle more and more. And because it's pulling more air, the ECU compensates and gives more fuel... and their mileage goes down. Then they complain that it's hurt more than done any good.
I took a trip this time last year from South Dakota to Tennessee. I avg 28 MPG @ 70 MPH for the trip down. 25 MPG @ 65 MPH the way back. I had the wind on my side on the way down, going against on the way back. All I did was just set the cruise control.
I avg 19 MPG city driving as well. 16 MPG right now with all the fun I've been having. Though some seems to be due to the fact we've used the Remote Start a lot lately, so the vehicle just sits and idles for about 5-10 minutes before we go outside and drive.
My advice, if you get the K&N... take it easy with the foot, you'll see better mileage.

Update: When I bought my truck in October of 06, I was getting 15.25 mpg w/ an OEM filter. My mpg has increased to 16.7mpg (all city driving w/ a V8) and I fully expect it to continue to increase.

Reason: Added more details
I use a Green Performance Air Filter in my Tundra and Camry. I like these better than the K&N. The gasket seemed to be a little cleaner cut. Gas milage increase? I haven't noticed any with the 03' Tundra, but it did seem to improve in my 01' Tundra(no longer owned) by about 1.5-2 mpg. Just my two cents.
Just get a weapon r dragon intake... +10hp and better gas mileage (if you're easy on the peddle) got mine at eautoworks.com... about half hour installation.
But as Reusable/washable filters are concerned, K&N uses better design not apparent to the laymans naked eye. They created the concept and demonstrate their product through Dyno testing. They are a solid performing company.
Then came Green, Blitz and TRD(rebranded from guess who?) .and the Knockoff, bargain copycats.
Good aftermarket air filters?
