I removed a Weapon R intake from my buddies VW last night, that is one terrible filter design, everything about that kit/filter felt incredibly cheap. I think that the Weapon R is a Joke honestly.

I have a Fujita that is cut down to fit inside my engine bay, I had it in the original position in front of the driver side wheel for a long time, but I cut it back to keep the filter inside the engine bay more. The filter doesn't get disgustingly dirty from road grime and tire dirt as easily in there. My filter was nasty every time I took it off. The Fujita, I would also STRONGLY recommend against if your live near a lot of water, it traps a puddle inside the intake duct when it rains heavily. I have heard of people hydro-locking engines due to intakes like this too, another reason I cut it back into the engine bay. I like the Fujita filters better than the K&N filter5s as well, they seem to flow better and dont require any oil or chemicals to clean them.
