These Denso spark plugs are very durable and last for a lot of miles, I honestly forgot the last time I changed my plugs and it ended up being 70,000 miles. I only started to notice a small hesitation about 1000 Miles ago and figured I should check them. I was blown away about how worn they were but still performed as good as they did! Denso all the way!!!!

These double platinum plugs are a definite upgrade frome copper plugs, they last longer BUT never downgrade fron Iridium plugs to these platinum plugs. Narrower point produces hotter (more concentrated spark). These double points concentrate the spark kernel resulting in a better combustion.

Great price, compared to local availability. Car was running quite rough. New plugs, new coils and an unplanned valve cover gasket replacement and the car. I longer throws codes. Runs much better.
