A necessity when riding in really dusty and sandy areas, especially when out for 3 or 4 days, just pull it off the filter and blow it off and your ready to go again, no wasting time cleaning filters instead i can enjoy more trail time.
i know i know , its expenceve 4 what it really is ,, but u aint got a choice. you need it and k&n has the best one. it looks cool and dennis kirk rules 4 using the real pic of the product. if your riding with ur airbox modifyed or off or even just the snorkel off , u need one of these . it dont rob no power eather so dont even think like that aight !!
