Hey everyone, Ive searched and havnt really found what I was looking for, Never have good luck with the search button lol. But anyway, I am looking at replacing spark plugs in my 2005 RXT and was wondering what all you use in your 4tec Rotax SC 215's???? Sorry again if this has been covered!!!

Well it depends on if your machine is modded or not...This is what is usually recommended...
Denso Iridium...These are a longer lasting plug..They will outlast the OEM ones 10 to 1..Alot of us use them once we make modifications to our machines...Here are the denso recomendations:
For a bone stock machine that doesn't plan on getting modded .... IXU24
For a machine with an air intake and anything more ... IXU27
If you want to save a few bucks then you can just replace them with the OEM ones which are NGK DCPR8E
..Which IMO will do just fine,especially in a stock unmodded boat/ski..

I have a stage 2 ski myself and with the stock plugs i would experiance a small bog/miss at start up when the ski is cold,Kinda like the cylinders were loading up..Once i switched to the Iridiums it was gone..I run Iridiums in both my machines and have had only one issue...BUT i have also had an issue with the OEMs also...Me personally i like the Densos over the OEMs...

Can you get both plugs at any auto parts store or are they marine stores only?

The iridiums you can usually get from Autozone..Some stores i have heard from other members carry them in stock,some have to special order them..There is a guy on ebay who sells the iridiums in sets of 3 for around 30 bucks..The OEM ones i used to get from the dealer..It was cheaper for me to do that then ordering them..BUT if you are intrested in ordering OEM ones i can get you a website were they can be ordered from...
Here is a link to the E-bay site were you can get the Densos for cheap..

I'd rather take my chances with the stock plugs. Even carry an extra set in your glove box if you're worried. Just hope they don't get any impact damage But seriously, 5 sets of OEMs for the price of 1 set of denso plugs
