KAX Premium Cabin Air Filter
Color: Premium-CF10285
This is our repeat purchase. Size of the filter matches with OEM product and it fits nicely in our car. The value adds are, I do not have to spend $$$ at the dealer, replacing the filter in every 2 years instead of 1 year and air filtration is much better compared to standard OEM filter. Kax team, please keep up the quality and you will continue earning my business. Thank you.
