was going to replace the spark plugs in my 2002 X-star with the 310 TBI engine. Currently there are AC 41-932 plugs in there. Any reccomendations on what to replace them with? I did a search on NGK site and came up with NGK 4323 or the irridium 2318 for this motor. Is it worth the extra money to get the iridium?
