I'm looking at buying a K&N cold air intake for my corolla. I'm wondering if anyone has changed to an aftermarket intake. If so what are your experiences? Also how was feul efficiency affected. Thanks in advance.
I'm looking to replace my current air intake with something after market. Was looking at the K&N 69-8757TTK Typhoon air intake. I'm curious if my mileage will be better. I look forward to your responses. Thanks in advance. My corolla is a 2014 S plus.
