Great product, easy install, improved performance
After watching a few YouTube videos I felt confident enough to handle the task. Spark plugs came quick and I was able to get right to the install. After inspecting the plugs for the proper gap, every seemed ready to go. Overall, it took be about 1.5 hours for the install as I wanted to make sure everything was correctly done. Install was smooth without any issues. It's been a little after a week after install and I've had no issues thus far. My truck had about 80k miles before changing out spark plugs and I've noticed an improved difference. Runs and feels smoother, gas mileage might be too soon to notice, but I'm positive there will be some improvements as well. Overall, the product has been recommended by the majority and I stand with them.

Cheap legit NGK iridium plugs
The plugs were exactly what I ordered. Brand new NGK iridium plugs at a great price. Shipped fast as well. Probably could have used a little more bubble wrap in the packaging but they still arrived undamaged.

Genuine NGK plugs
Buying NGK spark plugs online can be a bit daunting given the scare stories about counterfeits. I can confirm that the plugs I bought here (from seller Sixty Auto) are genuine. They have all the visual features of genuine NGKs, including smooth girth ring, talced porcelain, unremovable crush washer, as well as reading a consistent resistance of 5.5K ohms.
