NGK # 6509 Iridium Spark Plug LTR6IX-11 - 6 PCSNEW

These spark plugs are definitely functional and their performance is marvelous. Did not have any issues

Perfect plug for the job, Installed in 5.0 coyote. NGK best around

Worked great in 2014 Acadia. After replacing the spark plugs and the gasket, the car purred and accelerated great. I can feel the difference. I watched a YouTube video about replacement and I was done in 90 minutes. I haven't changed the spark plugs since we got the car at 70K miles, and now it has 160k miles.

These plugs were exact fitment with gap accuracy on the money! My vehicle takes off now. The engine runs much smoother than it was running! I believe I'm now getting the accurate gas mileage now... No Misfires at all. I hand wrench them all the way in, the grooves were exact! I didn't even have to torque wrench them. But I made sure they were at the accurate torque. I recommend these plugs besides the OEM plugs.

Muy buenos

The spark plugs came as a 4 pack plus 2 in separate boxes. All genuine. They were used in my Ford Flex with the naturally aspirated 3.5L V6. Keep in mind that the naturally aspirated and twin turbo versions of this Ford engine have different spark plug gap requirements. The naturally aspirated engine has a larger gap than the turbo version. Unfortunately I do not remember if the gap brand new out of the box was set for naturally aspirated or turbo equipped engines.

Good

Great quality spark plugs. Just fitted them to my 2014 3.7 V6 Mustang. Runs fine with no issues. No need to gap them as they're per gaped. Bought via a US seller and arrived in the UK very quickly.

Funcionaron muy bien.

Super mon moteur tourne maintenant sur tout ses cylindres

worked, no manual gapping required

Solo le faltó la huacita , rondana o aro en la rosca de la bujía, ahora estoy en duda de que acople bien ala hora de darle el torque ala bujía
