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.
então decidi retirar as velas que deveriam estar carbonizadas pela queima incompleta para inspeção, porém já que ia retirar as velas troquei as mesmas pelas especificadas no manual dl do veículo (vela de grau 5 de três eletrodos) ngk, o carro ganhou potência e lenta mais estável em baixa rotação, aquece mais rápido ao ligar pela manhã, só não conferi o consumo ainda.
Aspark plug change DIY costs me like 40 bucks
NGK 6535 is my recommended spark plug.
If they have a brand name plug it may be better to spend a couple $more for a NKG, Champion, Bosch etc. vs a china brand.
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.
Yep. Ordered some NGK iridium plugs on Amazon, 2600 miles later the car was misfiring. The gap was toast. Counterfeit for sure.
I’ve kept to stock plugs with stage 1. I tried the recommended “colder” plugs and they failed in less than 10k miles.
