Much better! Runs like new!
So far so good. They came gapped to about .042 ish. Adjusted to .035 for my 2012 f150 ecoboost and it runs like new! Old plugs were the expected .045 and just ran a little off... Put 500 miles on the new plugs and they work great! Will update if anything changes.

Works as designed.
Took less than 30 minutes to change all 8 in my coyote and made a huge difference in drivability over the motorcraft iridium OEM plugs. Will be my next choice when I need to replace again.

Great Replacement in 2009 Acadia
Have about 5,000 miles on them, so far completely uneventful. I replaced the stock platinum plugs with these after the engine started stuttering badly on steeper inclines around our house. Its apparent immediately that the car is much happier using these than what was in it to begin with. Didn't seem to increase gas mileage (I'd hoped they would) but running better is sure to be better for the life of the engine.

Five Stars
Great plug. Installed with no issues on my F150 each one had the perfect gap.

NGK Spark Plugs Rock!!!
I put these in my 2012 Chevy Camaro V6. Install was a breeze and I could definitely tell the difference in engine idle, throttle response and power when driving. I would recommend to anyone who's looking to upgrade.

Better fuel economy
I was getting poor fuel economy in my new truck. Tried high flow air filter which helped a little (1.5 mpg) but these plugs kicked me up to 18 mpg. Very happy with the performance. We will see how long they last but I have high expectations.

DO NOT BUY THESE!!!!!!!!!!!!!!!!!!
DO NOT BUY FROM THESE PEOPLE.The add says "One Pack" what I received was one plug!!! This is a scam so do not buy them. The plugs them selves are great but $10.XX plus $5.58 for shipping. For one plug!!!!! Man I want this job because a "pack" of 4 would be around 55.00 bucks and you can buy them online for $26.75- $42.00 for a "PACK" of 4.Again do not buy from these con artists!!!!!!!!!!!!!
