Great spark plug confusing delivery
The product seems to be fine. It's not the issue, the issue is that I paid $2.99 extra thinking that both of my packages would be delivered at the same time between 7 AM and 11 AM but I guess I was confused or not really given proper information.

Made my car more responsive
My original spark plugs were worn out and I knew it was time to get some new ones and I went ahead and purchased these which stopped my misfire issue and also has improved my MPG whenever I'm going to the gas station. I definitely recommend these spark plugs if you are experiencing a lag in throttle response or loss in power from your car.

2011 Nissan 370z spark plugs , half the price of the other guys
i drive a 2011 370z These spark plugs are exactly as described . they came pre gapped at the correct gap size as well . just buy them off amazon and save yourself half the money you would spend at those other places ! shipped fast and nothing was DOA . :) 5/5 would reccomend buying these.

Gapped perfectly for a 370z
The gap these are by default is perfect for the 370z, no need for a tapping tool unless you want to verify they’re all the same.
