Comes with printed instructions for those who haven't changed it before. Here is the specific use case from my van. On my 2014 TE its easy to access behind the glove box, open to usual full open then just push the left and right sides in to allow the glove box to come fully out. It may pop off of the mounts, don't panic it snaps right back on. Then look for the little rectangular panel with two small levers on either side. on the black plastic under the dash that you can now see and access. Press the levers and pull towards you, doing a bit of a wiggle to get it out. Its tight, but it will come out with having to break it. Don't gorilla hands it, it will break. There is a directional arrow on the filter, which you have to remove from the wrapper before installing. Yes, someone *will* forget that. Reassembly the reverse of removal. Check that video sharing site online if you need visual instructions.

Nice fit, quality look good too.

Just installed in a 2006 4Runner. Can’t speak to exact filter partials or longevity, but what I can’t say is that it fits very well and looks to be made very well. It actually fits better than the Bosh filters I normally use. Has a nice foam seal around all 4 edges and fits in the tray perfectly. Seem to be a nice option. So if you have a 03-09 4Runner it’s going to work well. Here’s some pictures of this filter (the blue one) next to a Bosh filter I removed. Also a picture with it in the factory tray.

The product is very high quality. I am impressed by how sturdy the filter is compared to the Bosch cabin filter i normally use. I will be buying this product again
