As ashamed as I am to admit it, I bought one about 7 years ago when they first came out. I was young and inexperienced and willing to believe anything! Haha... ok I was just dumb.
I didn't do anything for my Ranger. If anything made it bog a little more, figured if anything it was just hurting airflow. Took it out and chucked it about a month after I got it.
Sorry bryce-man but I'm with most of the other guys here, they are junk.
