Customer Feedback

So far, I'm very pleased. I'm getting about 10-12 better milage around town. This is from the readout on the dash, not my calculations. This is on a 2014 Subaru Crosstrek. I was getting about 26.3 average, now 29.1 mpg.

I replaced the OEM air filter in our 2013 Subaru Crosstrek XV with the K&N 33-2304 replacement filter. The K&N filter was a perfect fit and took only minutes to install. I have K&N filters installed on all my vehicles. We do a lot of off-highway driving, which requires cleaning the air filter at more than normal intervals. K&N filters are simple to clean and maintain and don't require any special skills to do the job. I highly recommend K&N filters for any kind of vehicle, whether for on or off-highway.

Does NOT properly fit 2014 Subaru Outback 3.6. A 1/4 inch gap exists on either side (L and R) when the filter is PROPERLY installed. VERY DISAPPOINTING AFTER WAITING FOR THIS TO COME OFF OF BACK ORDER.I called and your rep said it was the 'correct size. Since it is undersized, when the recirc feature is ON in the car, outside air can still enter the system.
