Nice write up grimmy. Good to hear your finally have done it. And you have all the space which i don't have at where I live.
So they ripped you off at the stealership? Glad you told us. But I know I won't let them do too much there. I have an auto shop which I used for more than 10 years which specialize in european cars. Can't really DIY coz I'm lazy and no place to do. May be I can change the air filter myself.
But seriously I'll change to K&N next time.
