Air Box Ports

1 post in this topic

I just added some ports to my air box. I noticed a little better throttle response from midrange to top-end. The manufacture of them is "Air-Ports". I bought mine for around $30. There are two 1 3/4" ports that install in your air box, one on each side. Very simple install and the motor seems to breath a little easier. I've always used them on my "two smokers" so I figured it would probably work on a more air hungry 4 stroker.

Two thumbs up!!
