Have another couple of thousand miles on it and still all good with no problems at all. A fellow DFW member gave me some intake tubes from a SL55 which was a big help. I was running the stock V6 tubes which were way to too small. I removed the plastic parts in each side of the radiator that the stock tubes hook up too. Before the change it sounded like a vacum cleaner sucking sound at high RPM's. With the SL55 tubes it sounds like a healthy V8 all the way to redline. Not sure how much power the it was costing me but feels and sounds better now.
