Very clear and precise video. Thank you. Some comments on high performance filters would be appreciated. The kind that you clean out with a spray -- these are supposed to last for a long time. Now, I feel more confident about changing the filter on my toyota 2015 Highlander XLS.
Well explained no bs thank you so much I changed mine yesterday both the cabin and engine air filter the dealer was gonna charge me just went for an oil change I’m in the middle of moving out had no time to the oil change 😂
If you see dirt or debris in the downstream side of the air filter that's a good sign that there is air leakage through the filter, either around the sealing gasket or through tears in the filter media. If, upon inspection, the filter media is intact I would suspect the fit of the filter around its sealing edges. I would put a generous coating of a synthetic grease around all of the edges of the filter gasket, ensuring a leak-proof seal around which dirty air can't pass.
The oem filter is obviously superior to the wix in this case.... You want an eye opener... Buy a napa gold oil filter, cut it open and compare it to the guts of a Fram. I did it and was floored by the difference. No more fram for this guy. btw, a good place to track the mileage is to use a sharpie and write it on the new air filter. ;-)
That's not the NAPA Gold filter nor any NAPA brand filter -- it's a cheap low end filter regardless of where you bought it. The NAPA Gold is made by Wix though and is better than the OEM filter. That is part # 9430. The equivalent Wix part # is 49430. The NAPA Gold 9430 and Wix 49430 look nothing like that filter you tested. That thing wasn't a Wix. I think it is very misleading. If you paid $13-14 for that Parts Master filter you got rooked.
Just a heads up. The 17801-0P051 is now unavailable from Toyota parts departments and is replaced by 17801-YZZ11. -YZZ11 has shorter media just like the aftermarket in the video.
i'd say 90% of vehicles on the road use this type of aftermarket filter..there is NOTHING wrong with it. all repair places (except possibly dealers who use oem parts) use quality, but still relatively inexpensive filters such as these. i go to walmart and every air filter of this type is nearly identical in thickness to your aftermarket..except the expensive washable kn filters. mine looks very similar to your aftermarket and was only $11, it is very inexpensive but the quality is still fine. a thinner air filter may ultimately just need to be replaced sooner,, mine states up to 2 years.
K&N will increase air flow, but it does that by not filtering as much, but still pretty good. So, on a racetrack, sure use it. But for longevity and maximum protection, I recommend Wix. But if you can only find K&N, it will work just fine
A DENSO air filter at RockAuto.com costs less that a Fram filter from Walmart.. I payed $8 for a DENSO filter. Even if it costs $60, you would pay that one time every 3-5 years ( Why go cheap ?? )
