Spark plug NGK or OEM Audi

Holy shit - $75 spark plugs? I think my Honda plugs cost like $5 a pop for NGK iridium

Also, you should probably go with NGK spark plugs because if you put Bosch ones that are made in China/Russia you are going to have a baaaad time

Currently will be doing all fluids, filters and spark plugs so the car is properly serviced.

Some of those markups are insane. I can get NGK laser iridium plugs for less than $70.

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.

Also check the spark plugs, sometimes people are cheap and buy autolites instead of NGK. Cheap plugs from previous owner give me a headache.

I had plugs from Amazon ngk and I had a wicked misfire couple days after. Somehow the ceramic broke off.

Please use original plugs for the replacements. Just yanked out aftermarket NGK platinums because of a misfire. For some reason, Mazda and aftermarket plugs in my experience always resulted in a misfire.
