New plugs

[Mavagrand]

Need new plugs for my 08 FLHTC. Don't want to drive all the way to the Harley shop. Anyone know the brand/size/ for an appropriate plug from Auto zone/Discount auto parts?

Hopefully one of these will help:

Bought some NGKs. I'll set the gap and install them tomorrow.

If (big if), your bike throws a code in the next few thousand miles, it may be the
plugs. Some claim that aftermarket plugs upset the ion sensing capability or sensitivity and throw a code.
There is almost as much controversy about this as which is the proper oil to use in a Harley.

I ran these same plugs for the last 20k miles, never had a problem.

Good. If you had used NGK's for 20K miles, and bought them again, just wondering why you asked for plug cross reference?
