Real good spark plugs by a good company!
I installed these in my 2002 Ford Mustang GT. They came gapped at .054". I checked each one to be sure. Its actually my recommended gap so I didnt need to make any adjustment. Easy to install I also used some anti sieze just to make it easy to remove layer. They looked to be a very well put together plug. I believe these will last a few driving seasons. My car idle smooth and had no misfires. The strong pulling was there felt like a new car again!

Huge difference in performance!
I installed these spark plugs in my 1999 Cadillac DeVille, and the improvement was immediate. Before replacing the old plugs, my car ran pretty rough. Acceleration was sluggish, takeoff from a stoplight felt painfully slow, and it honestly had no “get up” at all. After installing these, it’s like driving a completely different car. The takeoff is smooth and responsive, and the acceleration is noticeably stronger. It finally has that power back when I press the gas. No more crawling through intersections. Installation was straightforward, and the quality seems excellent. If your vehicle is hesitating, running rough, or lacking power, I highly recommend giving these a try. They made a world of difference for mine.

Best plug for 5.7l
Bought these for my 01 express 1500. I bought a crate motor 5.7l years ago and new transmission. It has been sluggish. Put these plugs in and woke my motor right up. I went to pull out of my driveway and normally I have to step on it to get going, I did a burn out with no problem. I will never use another brand, NGK is the only way to go.

Arrived in a timely manner, and at a good price. Thanks Amazon! Living in a smaller community means limited access to many many products. On line shopping has saved the day once again.

Work well in my Ford Crown Victoria. Word of advice, blow the plug wells out with air after removing the plug wires, and chase the threads before installing these if the spark plugs have not been changed in 5 years or more
