I got mine from Choi a few weeks ago and I love it. I love the sound of it.i sell em with trd filters.. they fit better than K&N..
mine are NOT disposable.. they are 100% reuseable..They're disposable (standard filter) - can't clean them except for with some compressed air. TRD filter - I like the K&N filter cleaner (really works great) and their oil which you should go very light with so you don't get oil on the MAF sensor and destroy it.
