NGK 93815 SILZKR6B10E Laser Iridium Spark Plug, Pack of 4

They work.

Perfect OEM fit for my 2014 Hyundai Accent. I've had them installed for almost three months now with no issues.

I replaced these spark plugs in my wife's 2012 Hyundai Accent SE. They are a direct OEM factory replacement & are supposed to last ~105K miles, but I changed the original set out at ~85K. Have accumulated about 2-3K miles without any issues. I did purchase gap tool and adjusted each one slightly prior to install to gap recommendations for the Accent. Looked up a youtube video & had these replaced easily in about 30 minutes.

Not cheap. 7k ohms + These ones got rid of the detonation i had from cheap plugs i ordered

replaced like with like. didn't wait till 105,000 did it at 60K, and was glad i did, as one plug was extremely difficult to get out with multiple rounds of PB blaster, heat up engine, PB blaster, heat up engine, let sit overnight, and again next day, Don't wait for 100k miles. no need for antiseize with these but i would consider a dab if i suspected how difficult it would be to remove

The Autolite plugs were installed 10K miles ago and almost from the start the car had random misfires on 2 cylinders. Installed the NGK which are original equipement has 3K miles and no problems the car runs as it's suppose to.

I am going to give these plugs a 5 star rating even tho I have not installed them. These are the same plugs I have in my car now and they have lasted 80000 miles and I get 40mi/gal. I thought I would replace before I REALLY had to because of miss fire or reduced gas mileage.

Good to find these one here, original ones that hyundai uses.
