Spark plug NGK or OEM Mazda

At 85k I swapped to NGK Iridium Ix plugs on my 2019 civic with the 2.0na and I swear it added at least 20% response. Makes me wish I would have gotten it with a manual cause it would be so much more fun to drive around town. Also got a few more MPG

I just replaced all 4 spark plugs on my car @ 114k miles. Now I’m so glad I did it because the car feels way more peppy and responsive.

I upgraded to NGK Iridium spark plug in my classic 500, 2 years ago. There were minor but good changes in performance.

The fuel economy increased a bit and the self starts have been better.

NGK, used them for years in multiple cars. Seem to last longer, but I have no proof.

New NGK plugs this summer and she\u2019s still purring away (and snarling when I drop the hammer). Honestly its one of the best motors ever to come from Honda and I\u2019ve loved both of mine.

At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.

Make sure you use genuine NGK plugs, otherwise you will have problems.

They are 2 hot for the engine , (the orange burns ) try colder plugs like heat range 8 NGK (SILZKR8E8G97080) are heat range 8 . The ones you have are 92422 are heat range 6 they are 2 hot . Same plugs fit my 2013 Veloster turbo fit your car .

I changed the plugs on my 2017 raptor recently with NGK iridium plugs. The punchline is that the truck started backfiring when I pushed it. I ended up putting Motorcraft plugs in and it cleared up.

It has 90k miles and we've been having issues with spark plugs. 3 months ago we replaced them after a cylinder 2 misfire. About a month ago same thing. Both times they looked terrible. Diode was all corroded and the threads had oil on them. Last night on my way to work cylinder 2 misfire came back. Anyway, I always use iridium ngk plugs as thats what's recommended but they are getting expensive having to buy them every month or 2.
