Nope, haven't removed mine. The rubber plugs aren't completely blocking the air from coming in though. You can pop your hood, pull them out, and see where the air can come in. There are ram air intakes for our cars too. All you have to do is take out the old intake and hook the new ram air system straight to the manifold. It comes with two filters(one for each scoop). It's just not a great idea if you drive it daily because if it rains, all that water will go straight into your engine. I'm sorry that I can't remember the link to the page where I found one. I looked just now to see if I could find the page again, but I couldn't. If you decide to do it, post it up on here and let everyone know the pros and cons in your opinion.
