K&N Cabin Air Filter
  • Electrostatically Charged to Hold Dirt and Dust
  • Easy to Clean and Reuse

This cabin air filter for our 2005 Highlander is much sturdier than the disposable factory filter and a perfect fit. Having installation instructions specific to the Highlander was an unexpected bonus, as gaining access to the cabin filter in the Highlander is not obvious.

Best filter ever. No comparison with the bad cabin filter that comes standard. Great quality. Looks and feels great and makes the car smell better. Honestly, big change when installed. I will only buy these filters from now on with all of my cars.

Not only was my shipping free but I got my part next day. This cabin filter may be more money than stock one initially. But it is much more sturdy & solid than the flimsy stock one. It should last the life of the car or at least while I own it.
