Spark plug NGK or OEM Subaru

Look good …. Just try to get denso or ngk

Switching fixed my ignition issues after having Autolite for only 2 days after purchase switched them to NGK and resolved my issues

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

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.

2018 Kia Soul Base, 57k miles, on the third set of plugs and they are misfiring already. Factory plugs lasted 30k miles, followed up with Autolite plugs lasting 10k (which I chalked up to being cheap/low-quality plugs), but now these NGK iridiums are giving out with 17k miles on them.

Just another rare earth metal to charge the user more for. Factory specs call for NGK Iridiums. I can't see a reason to deviate.
