### ⭐⭐⭐⭐⭐ 







  
  
    Just the Ticket
  

*by I***O on Reviewed in the United States 🇺🇸 on November 14, 2013*

This is the OEM replacement for my '06 Mx5. Three of the four plugs were gapped correctly out of the box, one ran a hair wide. After gapping them all correctly, it took me 20 minutes to change my plugs. My idle smoothed out and the throttle responds better. The engine feels like it did when new. Amazon charged a bit less than the dealer wanted, as well. I don't think I could ask for anything more from a spark plug.

*by A***R on Reviewed in the United States 🇺🇸 on June 15, 2017*

Received 4 spark plugs. One spark plug was bad. The gaps were all correct when they arrived after checking with gap tool. I found out it was bad after replacing each new spark plug with an old one after the car would not stop misfiring.

*by C***N on Reviewed in the United States 🇺🇸 on June 17, 2014*

Plugs arrived already properly gapped. Installation was non eventful. Applied anti-seize to the threads prior to installing. Had 60 k miles on old plugs and was amazed that they were still in pretty good condition. New plugs smoothed out the engine and I noticed a small bump in performance. I saved about 20.00 on 4 plugs as compared to local car parts shop.
