Wow...I'm REALLY sorry I forgot to mention this is all concerning the SE i4. That was really stupid of me...serious brain fart
I have no idea if the v6 filter works in the v6 or not.
So to (try) and be clear: neither TRD air filter fits the 2010 SE i4.
Also note: I don't think the engine changed, did it? I know the exhaust is different and, based on this experience, I suspect the intake is different as well. But I was under the impression that it's the same i4 as the LE, just not so de-tuned.
If it is a whole different motor I suppose that would make more sense.
Thanks!
