hey guys just put in my jets and put in a twin air filter, used 50ths shims would the snorkle and airvents give me evan more power and does just drilling holes in the airbox work also I have a 2003 where is the best place to drill the holes and I love to ride in the mud will I get water and mud splashing into the holes?
Thanks

 

The snorkel will pull cooler air from the front of the quad. If you like getting muddy, I would stay away from holes in the box. And yes you will see an improvement with a more free flowing snorkel.
