I've never been disappointed by K&N. Great filter, shipped sooner than expected. Hoping a cold air intake is in the works. Very happy.

This is my 4th K&N filter, first 3 were for my different cars. This one is for my Mazda Axela. It fits well and like my previous K&N drop in filters, it fits perfectly and I can immediately feel the difference in performance and fuel efficiency gains. The expected re-oil / cleaning every 8K-10K kms. (which is early by K&N recommends) is ok with me because I am OC on my air filters. Normally my friends re-oil approx 20-30K kms. Never had those blown MAFs (claimed by others). The delivery took only 4 days from when I ordered until I received it in Tokyo.

Shipping time was way too long. Didn't  notice any power gain. No future savings expected, as oem filter is cotton & washable too
