Spark plug debate - 2013 5.3 LMG

[Joseph Garcia]

Stick with OEM parts, and hunt for the best price. You won't go wrong.

Thanks for all the comments. I'll wait on the RA stuff. But my confidence in FedEx is waning. Package originated from Fullerton, CA and went to Perrysburg, OH where it has been stuck for the last couple days. But I'm in Vancouver, WA - directly north from CA. We'll see.

I appreciate the stories about the counterfeit parts and don't deny it's a big problem. But I seriously doubt the wires and plugs I'm looking at right now are counterfeit. Someone would have gone to such great lengths that it wouldn't be worth it. The only thing holding me back from installing the Delco stuff from Amazon is the fact that the plugs are platinum and not iridium, and don't want any performance loss.

I like RA prices but I never ever order from them if I have a deadline or in a hurry.

I don't think you would experience any performance loss when using the double platinums. The only downside is lifespan.

Iridium plugs and Delco wires finally came from RA on Friday. Got everything replaced and buttoned up this weekend - running good now.
