NGK Spark Plugs: Honda, Volvo Penta & Other Outboards

NGK Spark Plugs: Honda, Volvo Penta & Other Outboards

386 spark plug applications from NGK's catalogue, for the marine engines we supply parts for. Each line gives the plug NGK specifies, the premium upgrade where one exists, and the electrode gap. Plug codes shown as links go straight to that plug on our shop.

Check the gap before you fit. Plugs are not always gapped correctly out of the box, and the wrong gap causes misfire and hard starting. Where a resistor plug is specified, fit a resistor plug — a non-resistor substitute can interfere with a tacho, sounder or engine electronics.

Reading the plug codes

An NGK code describes the plug's construction. The digit in the middle is the heat rating — a higher number is a colder plug, which is the opposite of most other brands. An R after the first letters means a resistor plug. Codes ending IX are the Iridium IX range and G or GP the platinum ranges, both direct upgrades with a finer centre electrode. A Y- prefix is a diesel glow plug, not a spark plug, and has no gap. Where NGK specifies the solid-terminal build of a plug we show the base code, which is the one we stock — tell us if your leads need the solid-terminal version.

Do not substitute a hotter or colder plug to cure a running problem. A plug reading the wrong colour is telling you about the fuel, ignition or oil — changing heat range hides it rather than fixing it.

About the Volvo Penta table. These are the outboards Volvo Penta sold through the 1970s, which is where NGK files them. The MD2010 / MD2030 / MD2040 line is a glow plug for the inboard diesels rather than an outboard part. For plugs or glow plugs for a current Volvo Penta engine, ring us rather than working from this table — as the authorised dealer we have the factory parts data.

Not sure which plug you need?

Model families ran across several specifications and the year or serial usually decides which line applies. Ring 0412 532 984 with your engine and serial number and we will confirm the plug, the gap and how many you need. Our other workshop charts are on the reference charts page.
