NGK BR6HS Standard Spark Plug for Evinrude, Johnson, Mercury and Yamaha Outboards

The NGK BR6HS Standard Spark Plug is a nickel-electrode spark plug built for reliable ignition performance across a wide range of outboard, generator, and small-engine applications. Featuring a solid copper core for superior heat dissipation and conductivity, the BR6HS delivers a broad heat range that helps maintain consistent combustion under varying load and RPM conditions. The plug uses a standard ground electrode configuration with a nickel ground electrode and a nickel center electrode tip, paired with corrosion-resistant plating that keeps installation and removal straightforward even after extended service intervals.

As a longstanding OE-cornerstone design, the NGK BR6HS is engineered to match original equipment manufacturer specifications rather than compromise on heat range or electrode material for cost savings. It carries a resistance rating of 5000 Ohm, which helps suppress electrical interference in ignition systems that call for a resistor-type plug. Before installation, always check your engine and maintenance manual to confirm the BR6HS is the correct plug specified for your equipment, since using an incorrect heat range or resistance type can reduce performance, hurt fuel economy, or cause engine damage.

Frequently Asked Questions

What engines does the NGK BR6HS spark plug fit? The NGK BR6HS fits Evinrude outboards from 1977-2001, Johnson outboards from 1977-2005, Mercury outboards from 1976-1979, Spirit outboards from 1976-1981, and Yamaha outboards from 1999-2005, along with Chrysler and Clinton outboards from 1968-1986. It is also used on Chevrolet engines from 1962-1965, Volkswagen engines from 1954-1980, Arctic Cat snowmobiles from 1972-2000, Kubota power equipment engines, and Subaru-Robin commercial and industrial engines.

Is the BR6HS a resistor spark plug? Yes, the NGK BR6HS carries a 5000 Ohm resistance rating, which helps suppress ignition interference in engines that call for a resistor-type plug.

What is the electrode material on the BR6HS? The NGK BR6HS uses a nickel ground electrode, a copper center electrode core, and a nickel center electrode tip, combined with a standard ground electrode configuration.

Does the BR6HS have any OEM cross-reference numbers? The NGK BR6HS crosses to Ariens 20020001 and Subaru 065-01401-50, so either of those OEM numbers can be used to confirm you have the correct replacement plug.

How much does the NGK BR6HS spark plug weigh? The NGK BR6HS spark plug weighs 0.15 pounds.

Why does NGK plate the BR6HS with corrosion-resistant coating? Corrosion-resistant plating on the BR6HS is applied to keep the threads free of buildup over time, which makes installation and removal easier during routine maintenance.

Is the BR6HS a genuine NGK plug or an aftermarket equivalent? The BR6HS is a genuine NGK Standard spark plug, part of NGK's original-equipment-grade lineup rather than a third-party aftermarket substitute.

Can I use the BR6HS in place of a different heat range plug? You should always check your engine and maintenance manual before substituting, since installing a spark plug with a heat range or resistance type other than what your engine's original equipment manufacturer specifies, such as the BR6HS, can reduce performance, hurt fuel economy, or damage the engine.

What core technology does the BR6HS use for heat dissipation? A solid copper core runs through the NGK BR6HS to improve heat dissipation and electrical conductivity, supporting a broad heat range for consistent performance.

Does the BR6HS work in generator and small engine applications, not just marine outboards? Yes, in addition to marine outboard fitment, the NGK BR6HS is used in Kubota power equipment engines and Subaru-Robin commercial and industrial engines.
