ACDelco 41-108 Turbo Spark Plugs (Set of 4)

These are Genuine ACDelco 41-108 Iridium Spark Plugs, not to be mistaken for the cheep “Fake” Chinese plugs that have flooded the internet.. Don’t be fooled! Even spark plugs being sold on eBay and Amazon have been known to be imitations. We source these directly from our GM Parts distributor, enuring authenticity.

These Spark Plugs Some Pre-Gapped.

Note: Do not check the gap on iridium plugs yourself…pull them from the box and put them in the motor. Using a Feeler Gauge or Gap Tool could break the iridium electrode, or compromise it (causing premature failure sooner than later)
