Spark plug NGK or AC DELCO

I’ve replaced them alone (i’m not a tech, i am not even a beginner).

NGK plugs, 60 euros bought online, some tools i already owned, and I struggled with the spark plug socket, found it at a tech friend, the thing is that is necessary to be thin and i needed to borrowed a torque wrench. Half an hour of work.

Spark plugs took me 2 hours max to do myself. And it’s because I’m OCD so I was cleaning and taking my time. And it cost me $60 for the 4 plugs OEM NGK compared to $30 each at the dealer. Very easy to do.

I just got whatever the NGK equivalent was of the Denso IK22. One step colder works great on my car considering it gets thrashed. Comes up to temp extremely fast which helps fuel economy.

I've always used NGK plugs on my Hondas. My 2nd generation Fit I installed NGK Laser Iridium.

I went with NGK. Been great so far (been about 2k miles).

I replaced my own plugs. I got NGKs as I really like their quality.

I run NGK Iridium in my truck, they were like $17 each. That’s just my personal preference, I’m a boat mechanic and we put NGK in everything never had many issues with them except for these newer outboards running a weird plug that seem to foul after a couple hundred hours. I replace the plugs in my truck at like 250,000 miles. I currently have 370,000 on the truck and haven’t changed the plugs yet.

As an ASE honda mechanic stick to OEM Only which will be NGK lazer Iridum or Denzo Iridum plugs. Cheap plugs foul and cause wear and tear on ignition coils and other electronics. As well but not limited to possible system lean codes and fouled injector tips.

I pulled Denso plugs out of my truck and put NGKs in. Is there a difference? Maybe... But experience with Japanese industrial equipment says that Japanese engines like OE ignition components. NGKs are cheap and readily available.

On my stage 2 mk7 I swapped around and tried a few like ngk and the ngk failed causing misfires like crazy on acceleration. Back to OEM and never had another issue for 45k miles.
