Whats up guys. Just a quick question.
About a month ago i replaced my air filter with the k and n air filter. After I installed it the only thing I noticed was the sound of the engine was slightly deeper which was kind of annoying after awhile. Since I didnt really notice any performance increases and the engine sound is annoying me, I decided to replace the k and n with a regular air filter. Now even with the normal air filter in, the engine now still sounds like I have the K and N filter in.
Was wondering if anyone had any idea why this is happenning? By the way, I have a 2005 access cab v6 off road.
Thank you in advance
