Hey I am converting form a 97 Vdub, to a 2003 Xtreme. So far, the Xtreme in the one week of owning it, is 10x funner. 4.3L's are pretty quick compared to a VW. Anywho, I bought this truck brand new, only had 172 original miles on it. My question is, when should I service the first oil change, and how many miles on average does it take to break in a new engine. Probably stupid questions, but I know nothing of new vehicles. Another question I have is, does the K&N intake with the Gibson cat-back make a huge difference. Just curious if it is worth spending the money.
