QC10s or QC12s

[rude power]

have noticed they recommend the qc10 now in the 225s an 250s ,should I change from the qc 12s to the 10s or are they ok in my older motor?? QC10wep or QC12wep?

The QC10WEP with the E-Tec T-stats will last longer in your engine.

thanks Danrude ,the gap on the 12s doesnt seem to last very long,maybe 2months and they are at 40 to 45 from 28.

The QC10WEP plugs have an iridium electrode and will last a lot longer in an older FICHT engine.
