Truck runs great have had them on for 2 oil changes about to do a 3rd and still running strong

Fast shipping perfect fit

Everything was in good working order and was speedy delivery.

My vehicle was still misfiring and running badly. I had to purchase more spark plugs locally. This was a major inconvenience for me. I ended up missing a day of work as a result of this.

Very nice quality

THE PRE-GAP IS KEY

bought them last year for my suburban 5.3L 2017/ shows compatible NO ITS NOT ??/ no return / collecting dust in my garage FYI the threaded neck length Super important : in my case the 41-114 # should have been my guide not amazon telling me it fits??

The price was great however these went in a daily driver and have 14,000 miles on them look at plug on left I have had 100,000 miles on a c delco plugs that look brand new when removed I purchased these along w dragon fire coils. The coils work great but I won’t purchase dragon fire spark plugs again
