Decided to replace oem spark plugs while I have the plastic off the Wee. Surprised when 3 major parts chains near me had none of the iridium NGK's. O'Reilly found 4 in a warehouse 4+ hrs S of here. Don't want to wait 'til next week for them so I paid the shipping to get them tomorrow. Amazon shows they have them but the guy that waited on me has helped me out before so he got the business. No cross refs either. Are there any that anyone is aware of?
