I can Google "Toyota air filter MAF sensor" or "Motorcraft air filter MAF sensor" or "Mopar air filter MAF sensor" and not find any complaints about MAF sensor failure. That's because OEM paper air filter elements do a superb job of cleaning up the intake air. And Toyota goes a step further by using a triple layer air filter element.
TRD claims only a 2% horsepower gain @ 5000 RPM for it's K&N like air filter. That's too negliglble of a gain at too high of an RPM to notice except in full throttle 1/4 mile dragstrip racing.

I never, ever claimed K&N was a big or even marginal Performance advantage. Never.
K&N even states this. They will only claim a specific and substantial perf. boost if they can qualify it with dyno results to specific apps.
It's a practcial Air filter that can do no more harm than an OE in my opinion.
I can see this "Wet" design filter be a concern in theory, however, this hasjust not been proven with the K&N drop-in replacement filters. K&N>MAF failures is just not proven. And it has been disproven over and over.
I am not a fan of ALL of the K&N stuff.
I do believe that K&N OIL filters, among a few others, are superior to any OE Toy spin-on with the possible exception of the OE Toy-20003's and 20004's and most of the TMD oil filters.(not available in the USA)
The round "O-ring" seal design of the OE's have leaked and will sweat oil at the bottom of the can as mounted to the block. I have never noticed this on the "flat" design seal of others.
I pick and choose my aftermarket stuff very carefully. 99% of OE stuff is great. OE air filters are the best at what they do. Sure. But there are viable alternatives that are ok too.
TOY oil fliters are my biggest beef for sure. Another topic. Another place.
KR, yu are way too strict in your thoughts.
Can yu tell me why absolutely everthing must be OE?
Without citing Toyota propaganda material?
Is that all yu have? Surely yu can do better than that.
You'r not a "layman" or are yu.?
But, if yu want to hold KR's hand....go for it, she needs some assistance anyway.
Well, that's all you had, so I figured it was enough for you? The truth is, every independent study I've seen, the K&N has performed poorly, especially compared to some Toyota air filters. Poorly, meaning dirt getting past the filter, as well as a greasey residue in the throttle body, also much less filter area, equating to less CFM.
I'm a layman if that means I have never had formal or informal training on anything related to an automobile, never been involved in or with any automobile related business or industry, never had any family or friends in any business related to automobiles.
I don't need to make insults to make my point, not to say I won't.
BTW, why do you quote your own posts?

I have tried K&N and other Cotton filters in 4x4's, and they do flow more than older standard filters, they do let a lot more crap in. The oil soaked foam filters don't let much air thru, but do block a lot more dirt (we dynoed a IMCA with and without Foam filter, there was a 10hp gain (at the wheels!) with a clean cheap paper filter (14" x 4"). In speedway, there is not much dust, so the better filtration was not required.
In the dust here in Australia, the K&N style filters get a bad rap, but they do make more power.
I guess is you are in the city, they would be better, but not in rural areas.
