The factory and Vans carb boxes were not made fireproof- therefore a big induction fire was a real problem.. Maybe they've changed ..?? I clean the K&N Filter each year--quite a bit of dirt and I operate only off paved surfaces.. So I don't concur with the post to use unfiltered ram air, it doesn't give you more MP..
