NGK OEM Equivalent Spark Plugs?
 

Anyone know which NGK plugs are the right plugs for our use?

I've found one source that says they're Iridium IX 5687, but haven't found anything to back it up with. Can anyone confirm?

Considering NGKs website doesnt list any that would be none.

Only the OEM plugs are an option still

If you're looking for a better plug, Denso makes some for the JDM. They're quite a bit more expensive, but both the electrode and ground strap-- or at least a little part of the ground strap-- are made from platinum group metals-- iridium for the electrode and platinum for the ground strap. The electrode is also the narrowest you can get, which in my testing was the most important factor for a reliable spark.

Thats actually cheaper then OEM from many places lol

That doesn't necessarily mean there isn't one that's totally equivalent, it could just mean their site is out of date. The lookup on their site only goes up to 2014 for any manufacturer, so it's two full model years behind.

I had mine replaced with NGK plugs and have no issues. Wish I could help on the part # they used, i had a tuner shop do it for me.

Check your paperwork, cuz they obviously know more then the forum does. And the OEM plugs are a grip from most dealerships

What are boosted guys running for plugs? any re tuning required for different plugs?

nick stfu, thought you were parting out??
