I'll re seal the air box a bit soon.
As for the curing it, I'll have to search the forums, but is the TB easy to remove to clean, (or replace considering I have a brand new one sitting in my brothers room in the package)
((I'm 18. Got a BMW. My older brothers friend is a lead mechanic at Sterling BMW, gave my brother some parts to sell to me when needed.. Parts that commonly go on the E46.))
Also, I've seen TB spacers, which claim to add more power on TurnerMotorsport.com.... any ideas? Would it be worth getting? They claim an extra 10hp.
