K&n might be better if it at least seals around the edges.And you drive in dust every day. Not good. Could you plug the gaps with some foam weatherstrip tape?
Might as well run a K&N.

The old filter was too small also. That's why my air intake is full of dustI know this sounds stupid, but is there a difference in the size of the filter presently installed and one of the new ones? Which dimensions are wrong, comparing filter to filter?
IF the housing did "grow" over time, then the existing filter should be too small as well.
Did you do oil analyses and drive in the No. California desert?I have one on my F-150 and a previous F-150 that I drove to 225,000 miles they do work.
Only service by me since we bought it a few years ago. In the past I noticed it but thought it would "self center" when installed. It won't. There's no way to guarantee it's centered when I put the lid on and no way to tell if it did or not.Did you do oil analyses and drive in the No. California desert?
If, and that's the biggest 'if' I can imagine, you use an undersized filter element and fill in a gap, carefully fabricate something substantial using wood and silicone rubber to effect a real seal.
No foam or tissue paper.
Good luck.
Shouldn't the very next consideration be ridding the air intake and engine of accumulated dirt?
edit: I reread post #1 and see this is your vehicle. Is this the first time you've serviced it yourself? Nothing seems plausible here.
It "couldn't've" left the factory that way. You never would have installed that element yourself or failed to see the incorrect size.
Did you have it serviced by someone else before?
This is actually mind-blowing. Excuse the sixtiesism.
Just this one. The filter goes into the plastic housing and not onto the engine it's self.How many engines did Toyota offer for the FJ ? Maybe it's not the original engine .
I can see with my eyes that the filter is too small to completely cover the intake "hole". I wish y'all were here to see the problem. My next guess is that the plastic housing " grew" somehow . In the past it sealed ok.Obviously none of us are standing there with you, but I think these filters are actually OK. Don't look at this as one piece of a puzzle; look at the whole puzzle when assembled.
- the air filter itself fits into the "upstream" side of that sub-assembly. The pleats get pointed upstream. And the whole filter fits inside of the "male" part of the filter (attached to the flexible hose).
- then that sub-assembly fits itself into the main house which is attached to the engine. So it becomes centered once the sub-assembly is placed into the main assembly.
Don't try to fit the air filter into the main assembly on the engine. Rather, see how well the filter itself fits into the upstream intake tract sub-assembly.
The air filter is a "male" component to the female part of the upstream intake housing, but then that combo reverses roles and becomes a "male" part to the main housing on the engine (a female part).
(look closely at the video that SC Maintenance posted on the previous page)
The filter fits inside the upstream housing, then that upstream housing fits inside the main engine-side housing.
I think there is absolutely nothing wrong with any of those filters; you're trying to judge the filter fitment to the wrong part. Mate it to the upstream intake housing, not the downstream main body.
That's as best i can tell from the various videos posted in this thread.
It’s entirely possible that the filter box has warped. A new filter box is going to run you around $600.I can see with my eyes that the filter is too small to completely cover the intake "hole".

So wix, napa, and Purolator are likely all the same from M&H - just guessing? Maybe different materials, but maybe off the same pattern.I've tried wix,Napa, stp,champion, Purolator, super tech
Denso aftermarket are often not the same as dealer/OE Toyota Denso filters. I have seen aftermarket Denso combine part numbers on air filters with similar dimensions, where the dealer offered each under unique part numbers.So wix, napa, and Purolator are likely all the same from M&H - just guessing? Maybe different materials, but maybe off the same pattern.
Supertech and Champion are first brands. I think STP might be also.
I am interested to see what the Denso does. I presume Denso is the OEM supplier to Toyota - but its not guaranteed - even though Toyota owns most of Denso.
