Just got my '05 Blaster last Tuesday. Bone stock, still has the stock tires on it. I'm the 3rd owner, and got it for cheap. The only thing this bike needs is a air filter. I have to run a intake because I will be going through the wet stuff from time to time. I bought the quad as is, but it needs a air filter cage and air filter. I was wondering if I just bought a K&N if I even needed the air filter cage? It would seem it is rigid enough to hold its own shape. If not, I will just buy the cage and a UNI air filter. Thanks in advance.
