Spark plug NGK or OEM Audi

I changed my plugs recently and qent with NGK Ruthenium gaped a step colder and they are working well for me, seem better than Motorcraft but thats just my opinion.

I just did the 30k service and my mechanic recommended these plugs. They are expensive, but worth it.

Learned 40 years ago to use NGK. Installed brand new Autolite plugs in my girlfriends Grand Prix and it ran like crap. Went to a speed shop and they sold me a set of NGK. Ran perfectly. Have only bought NGK or Denso since.

I used these in my '19 with no issues.

spark plugs every 30K with NGK IKR9J8(Iridium plugs better than stock also used on high HP builds). I don't care that the manufacturer suggests longer intervals but i know my engine is healthy and runs almost like new.

NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent.

My 500 sport rocked copper cores good for 30k and at 38k, when I bought it, was misfiring like mad and stumbled a ton at startup, swapped $14 a pop NGK Iridium IX Plug Number DCPR7EIX and runs like a dream

I replaced the OEM plugs with NGK, they lasted about 15,000 miles. Burger Tuning told me that 15k is about all you'll get out of NGKs in these cars.

Also dont use plugs for tuned cars if youre not tuned. Tuned cars run colder plugs. They are not the same dont listen to some of these comments lol

That gap is INSANE, or at least appears to be.

In case you were wondering why those plugs look different, that plug on the left you’ve chosen (BKR5EIX11) is a plug that doesn’t match the longevity characteristics that Nissan originally set. The electrode basically isn’t designed to last as long.
