Review on 🔥 NGK DILZKR7B11GS (95710) Spark Plug: Unleash Optimal Performance! by Chris Burns

Not sure what happened here but I installed them in April 2020 and noticed yesterday (10/05/20) that my engine was running rougher at idle with brake lights on the go to get some food. I immediately went to the auto zone and bought the exact same candles for $90 (4 pieces). I came home, took them out of the car and compared them to new ones from the auto zone. The lettering on the NGK was much lighter (less bold) on the old ones compared to the Autozone lettering and the threaded part didn't look as shiny on the ones ordered from Amazon. the boxes also had different intensities/grey levels. I sent them back and am writing a review because after adjusting (to 13 ft/lbs with a torque wrench) Autozones my engine (13 Civic) is back to normal! no rough idle, and gas mileage jumped from 29.7 to 30.0mpg in 28 miles. Interesting. At this point I came to the conclusion that these forks sold on Amazon might be scammers. From now on I buy the same expensive car parts in reputable car dealerships.
