Save your old spark plugs just in case
After having these for about a month and a half I gotta say these are not worth the hassle. I had put these in my 2014 Hyundai Santa Fe sport as these said they were compatible for my vehicle. The fitment felt and seemed fine as everything ran fine for the first month or so. Then, out of nowhere my vehicle started acting funny as my RPMs started zeroing out for no reason. Felt like if the engine had shut down but still running with less power. I would pull over not knowing what to do next. So I decided to just turn the vehicle off for a few minutes and hoping that if I turned it back on it would work again. Fortunately that worked everything started running fine again and I was able to continue my trip. This symptom keeped occurring everyday from that point on. I ran it like that for about another 2 or so weeks tryin to figure it out as I was not getting a check engine light at all. Until finally one morning I was at a red light it felt like the vehicle wanted to turn off like it wasn’t getting enough gas or something. So I decided that I was gonna replace the spark plugs even though I had just bought these. Luckily I had saved my old ones which still had atleast 10,000 miles left on them. Well go figure after reinstalling my old ones my vehicle started running great again and it has not dropped RPMs or felt like it wanted to shut off. It’s already been 3 weeks since I’ve ran the vehicle with my old ones and still no problems. All in all either my vehicle didn’t like these or they were just cheaply made. I’ve learned my lesson and sticking to the regular gapping spark plugs. Now I gotta go to the auto parts store to get the same ones that I’ve had in my vehicle. Autolite seems to be working just fine with my vehicle

Excellent Quality
Needed to perform a tune-up in my wife's car since the spark plugs had never been changed since 2014. Immediately noticed a huge improvement in the car's response! I recommend the great plugs to anyone looking to upgrade from a factory setting.

Noticeable difference
There's absolutely nothing better than installing a new part in your car and immediately feeling the difference in performance. That's exactly what you'll experience with these spark plugs. Not having to set the gap specified for your car is a plus.
