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

Does it fit sea doo rxtx 300 2021

Nope. The high performance engine takes a different plug I’m not sure of the # You should be able to find it in the listings
