Lord Jesus Christ. I spent half a day pasting it myself and it wasn't easy because the instructions are acceptable at best. But I'll tell you what! The sound it produces and the extra power it delivers are worth the wait. I stupidly installed an airflow sensor in reverse and my GT wouldn't start. A quick call to K&N got me up and running. It's too early to tell if this will get me the fuel economy I want, but I'm sure if you stay away from it you'll be spot on. 10/10 K&N
