I think it's time to replace plugs in my 2005 496 HO. It has 245 hours on it and I doubt they've been changed. Please take a look at the description below to help me confirm my choice. I've read a lot of the posts and I've decided to go iridium and I think Denso unless someone has a compelling reason not to. The followin is from sparkplugs.com and there are probably 20 different selections for the 496. Motor is completely stock and has a miss when she first comes off the trailer and makes it difficult to get on plane. Once running it clears up and no more problem.

Should I change plug wire? Thanks!
