Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh. 1) Over designed and built (Good thing) installed without effort. 2) Fit and finish is perfect for my 2016 Genesis G80 3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years. 4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control. Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.

Better Than OEM – Worth the Upgrade
Size: 1" x 1" x 1"
The K&N filter is a big step up from the standard Toyota air filters and OEM replacements. Installation was quick and easy, and the fit is perfect. I’ve noticed smoother airflow and better throttle response compared to the stock filter. The best part is that it’s washable and reusable, so it’s a long-term investment instead of constantly buying replacements. Definitely a smarter choice for anyone who wants performance and value over the typical paper filters.
