OEM Replacement Spark Plugs - ACDelco Part Number?
Going to replace spark plugs on the Cobyashi Maru.
Been reading up on threads, but a lot of them are older.
I checked on Amazon and found ACDelco plugs (part #41-103) but have found other threads here stating that ACDelco part #41-981 is the actual replacement.
The 981's are $17 bucks a pop on Amazon, and the 103's are ~$7 a piece.
Car is stock, but planning on CAI and catback in the next 6 months, if that makes a difference.
Seen a log of threads on plat vs. iridium vs. double plat, but a lot of the threads I am finding are much older (some almost ten years). Just curious if anything has changed since the info in the threads I am reading.
As always, thank you!
