Re: Fuel Controller questions
I can think of three, relatively simple things. In decreasing order of preference, they would be:
1. Snorkel the stock box and put a K&N on top of the snorkel. The K&N's make great pre-filters
2. Stock with a Uni-style oiled foam wrap. The stock paper isn't really too bad, it just gets overloaded with the leaking air plumbing, seal, location, etc.
3. K&N in the stock airbox with a Uni-style oiled foam wrap
I have a full, bulldozer-style Donaldson mounted to the side of the bed, with direct plumbing to the throttle body, with 5 stages of filtration if you count the Outerwear and the filter turbine blades as a stage. It's massive, and nothing gets by it. It's overkill, but after my engine seized from the dust problem and I got a new motor from Polaris, I wasn't going to let dust kill it.
