I run NGK on my 15. The car runs great doesn’t miss. I used OEM Denso 5339 but they lasted 10-15k but then I tried NGK 92182 and they’ve lasted bout 40k so I’ve had no issues with them both of them Iridium.

Pros: car runs great, no issues

Cons: Denso short lifespan

Vehicle: Ford Focus

Mileage: 40000 km

Part number: 7243

For spark plugs I always used NGK because that's what Motorcraft actually uses if I remember correctly. Autolites are complete garbage and always fouled out the few times I used them.

Pros: reliable, better than Autolite

Cons: Autolites are complete garbage

Vehicle: Ford Mustang

You can honestly just run stock plugs on the 1.8 with OTS tuning for stage 1/IS20/38. I ran these same VW/NGK "RS7" plugs including track use for thousands of trouble free miles.

Pros: trouble free miles

Vehicle: Volkswagen Golf

I forgot to mention that I installed brand new pre-gapped NGK spark plugs two years ago

I like NGK, but you can't go wrong using what the manual calls for.

Pros: can't go wrong

Replaced spark plugs on a 2009 Corolla 1.8L. I used NGK plugs, should I swap out to Denso?

Damn $40/plug, I have a nissan altima 2012 and got the most expensive one at $30CAD/plug NGK iridium laser and it was out of necessity as cheaper ones was out of stock during lockdown.
