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.
Pulled the plugs and the center electrode is rounded off pretty bad. Gap is more than twice as much as spec. After replacing the plugs with OE NGK the bike is back to purring like a kitten so it was the plugs for sure.
Only spark plugs that should go in Euro cars are NGKs or Bosch.
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.
Get those plugs out! I bought counterfeit NGK plugs from Amazon. By the time you get a misfire the ceramic may have cracked off around electrodes and damage your engine.
