Spark plug NGK or Denso

NGK Spark plug

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.

Pros: never had many issues
Cons: plugs seem to foul
Mileage: 250000 km

NGK Spark plug

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.

Pros: OEM plugs are best
Cons: cheap plugs foul
Vehicle: Honda

Don't think the platinums give much of a performance advantage and they foul faster if you've got any oil burning going on...

Cons: foul faster
Vehicle: BMW
