Got a PM saying that it just pops off, and he was right cause I just went out and popped it right off. It's a little stiff to get on and off but after you get it off you'll understand how it works. Also I would like to ask; how bad is the restriction on the intake? It doesn't seem to be that bad or am I wrong about this? The stock air filter looks a little restrictive and that's about it to me. Just my 2 cents.
