Hi. I have been trying to find alternative spark plugs for my 2006 X2 with the RTP1 engine. My local shop quoted AC Delco plugs but at over 18 ( 20 dollars?) a plug. I've tried searching the forum (no luck) and tried spark plug finder web sites but they don't seem to list boats. As I'm changing them every year do I really need long life plugs like these??? I've always used NGK plugs on other boats - can't find the right one though. Any info? Thanks in advance. :)

No need to change them every year unless you're putting ALOT of hrs on.

Yeah I know - but they are due to be changed. Been in for at least 2 years now since I bought it.

That price is crazy. I purchased plugs for my 2006 for $5 per plug. Try napaonline.com

Sorry, thought you changed them every year.
I assume the ones you were quoted are stainless steel plugs, which here are $5-6 ea, about double that of non stainless steel plugs. If your boat is not left outside, wet bilge, humid, etc, use regular non stainless steel plugs. Ran them for years in my PS 190 with no problems removing them........but I am in a dry climate and my boats sit in a garage, nice and dry 300+ days a year. It'll save you some money and if you're replacing them every year anyways, they won't rust in.

How'd the old ones look? How many hrs on them? I'm only at 100hrs on my 06, so haven't even cracked one loose to look at it.

Interesting observation, just bought a 4 wheeler, 23hrs on it, like new. Bought 2 spare spakplugs and decided to replace the Champion OEM plug in it, just 'cause I don't like Champ plugs. The OE Champ plug had the lower ceramic insulator, the one down around the electrode, come loose and it just slid freely up and down the electrode. Damdest thing, glad it didn't break off in the cyl! Chalk up another reason I don't like Champ plugs!
Idles better and less backfiring coasting down hill now.

Thanks for the info so far. I was hoping someone could give me the correct codes for other makes of plugs. I could probably find them okay in the UK but I don't know what to buy. Cheers!

That's great - thanks for the help. I've found the NGK plugs now for less than half the price and in the UK. Any ideas why the Delco plugs are so expensive?

just found a conversion for over here in the uk for NGK plugs it says the equivelant plugs in NGK are PTR5D-13, Mine are the same plugs in the 197 mcx engine acording to the manual just had a look on flea bay dealer has them at 4.05 buy it now could be a good deal.

They're from the US, not Far East. Also, it's likely that fewer cars and trucks in the rest of the world use AC plugs because they don't use GM engines made for the US market.
