We've had this discussion, warranty means very little when the part that's holding it is subpar. Someone puts ot much stake in buying subpar products and needing a warranty than buying something quality so they don't have to worry about it.Are they the NGKs with the 60 day warranty? Nothing wrong with NGK spark plugs except the Company doesn't stand behind them warranty wise. Something's fishy there. They aren't telling us. Denso is one better = no warranty. Even SKP and Bosh have a 12 month warranty. Mopar has 24 months. Whoopee. Split peas for split pea soup last longer than that - used some this week with a best before date of July, 2019. The soup is good though.
The OE spark plugs in the 4th Generation and the 5th Generation were Champions - tried and proven beyond a doubt.
Mysterious miss for sure, I don't have it.
Funny that the "Mopar coils" list 24 months when the Mopar coils are Denso...
Same person who changes their oil but doesn't change the filter.... Much like cleaning your child's poopy butt just to put the poop diaper back on them..
