Do these fit a 2004 sea doo gtx le rfi?

I had one of these. Decent ski in the day My records show it uses an NGK BR 8 ES With a gap set at .45. This should be pretty easy to find on amazon or at local parts store that is near a lake where there would be demand At $3-$4, Get extras. These engines where bad to foul plugs It was always easiest to pull the plug, throw away and replace Hope this helps, Stewart
