Reviews of NGK spark plug

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 changed my plugs for NGK IRs but now I have a rough idle when the engine warms up.

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.

95K, swapped for NGK laser iridium’s (OEM replacement) plugs and since then have had rough idle but when driving feels fine.

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

I got a new set put in some NGK’s.

Yeah, NGK's are great. Get the best you think you can afford.

I like NGK's iridium spark plugs personally
