I just did mine... and I removed a OEM/Denso and bought a AC Delco and it didn't fit as tight...
Im sure there could be some differences regards to filter material or spec...
Personally I try and avoid things like the reusable K&N filters after a pretty piss poor service experience with someone trying to clean one.. and they also look like they let more crap though than the OEM stuff.
That's all the experience I have with it, but I think next time around ill probably buy a Toyota / Denso filter.
