OEM Replacement Spark Plugs - ACDelco Part Number?

Hey everyone,

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!

-Jerm

ACDELCO 41-103 IRIDIUM SPARK PLUGS GM#12625058 is the right plug for your car. The other one will work but it's a platinum plug and will not last as long as the dual iridium. I have 100K miles on mine and still waiting for a misfire count to change them..

Awesome, thank you Coby.

Will these spark plugs still continue to be the preferred part with the CAI and Catback in the future or will I need a "cooler" plug? I don't think the CAI will cause that much of a difference as far as the spark plugs are concerned, but I still want to ask the experienced ones.

Thanks!

No change unless you change compression.

Wunderbar!

I got the plugs ordered. Should be here today or tomorrow.

Also ordered some grease for them. I have never used grease when changing my spark plugs (I know, I know..)

That being the case, how much should one use per plug? Just put a small dollop on the end of the plug once it's installed and then secure the boot or..?

Thanks again!

Just FYI, I've got a CAI that I'm trying to get rid of. There's a thread over in the Sales subforum.

Just a dab inside each boot. Also put a bit of anti-seize on plug threads

Just a note, I read on ProDemand that anti-seize is NOT recommended on the 2.2L... but personally I would use it.
