Do not buy this junk
Ordered on January 31 installed it on March 19. I’ve started my sick times with it since and now dead absolute junk. I would highly recommend staying away from this.

Save your plastic cage on the factory filter
This fit the plastic holder that comes with the factory filter. Make sure that you don’t discard the plastic “cage” that is on the factory filter. Reuse the cage with this filter.

Good
24 Camry, V6. A little bit different then OEM, just had to tweak the filter a tad, not a big deal but just letting you know. I would still get it again
