The filter size fit perfectly on my turbo 2001 Integra type R. Space was very limités. Very fast shipping.

Ordered for my 83mm short ram intake.. The first one came damaged.. only slightly.. the box was smooshed/bent in a little causing slight damage to the filter.. I contacted K&N and was initially just telling them of the problem, didnt really need to return it as it was still in working condition. They looked over the pictures, didn't like the look of the damage and sent out another one that arrived a few days later.. I live within hours of their place, so shipping is nice and fast for me..good quality.. been using K&N air filters forever without problems. Will I reorder again? Yes, yes I will!
