Overview
NGK sells this standard plug as a single unit with a copper core and a ceramic top. The listing offers a part number and a list of numbers from other makers, and the seller copy says nothing specific about the plug.
The case for this plug is a recognized name and a long cross-reference list for matching an existing plug. The data is thin on the figures that decide a swap, since thread size, reach and heat range are not listed.
Who it's for
A DIY owner or shop matching a plug number from a manual or old plug can use the cross-references to confirm it. Buyers working from the engine alone should confirm specifications elsewhere, since the listing leaves them out.
Pros and cons
- Copper core conductivity
- Long cross-reference list
- Single plug pack
- Thread size not listed
- Reach and heat range missing
- Item type row reads accessories
- Seller copy is generic
Performance notes
A copper core conducts heat and current well and carries heat away from the tip. How the plug behaves in an engine still depends on matching heat range and reach, which the listing does not state.
