Great replacement option for spark plugs on R1200GS(WC)
Replaced OEM spark plugs during my 12k service R1200GS(WC) with these due to recommendation found on advrider forums. I cannot say they are any better or worse than the OEM plugs, but these certainly seem to work great.

These are great replacements for my '14 BMW R1200 GS ADV stock plugs
Direct less expensive and longer-life replacement for the stock sparkplugs
