Spark plug NGK or Autolite

I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.

Just swapped all four plugs in my 2013 Kia optima EX 2.4l for ngk iridium’s, still had the original sensor plugs in at 91k so honestly not sure how I didn’t have any misfires but have had a rough idle

They are very picky with their spark plugs so you are limited to NGK which is oem.

worked for nissan and honda as a tech and i will always recommend ngk laser iridium spark plugs. use them in my own vehicles and perform well

Replaced the torch with NGK BP7ES. Non resistor and run exclusively on propane. All I can say is my WGen 11500 starts every time on the first or second turnover. Torch it would go anywhere between 4 and 7 before cranking. I just know Torch plug sucks.

Swapped the spark plugs w new OEM NGK ones and 0 misfires 0 errors and car runs like new. espeacially notice a difference on start up and idles smoother

My WEN, brand new out the box, would always require a shot of starter spray, take 5 or 6 hearty pulls, and ran rough. Pulled the plug and the stock is a Torch!!! I installed an NGK and it cranks on the 2nd pull and runs smooth as silk.

Lol 560 for 4 piece spark plug? That plug better be made of gold even laser iridium also doesn't cost that high. Good ngk iridium cost no more or less than 300. That syn 3k for 300 can get a far better brand n enhanced thermal and oxidative stability grade.

Also, Autolite is extra terrible. I would have done anything else.

Local mechanic used an Autolite plug, not Honda-recommended NGK. Misfires stopped for a month, then happened twice more. I have since discovered this brand does not run well in a Honda engine.
