Mercury NGK Spark Plug BU8H - 13686Q

The NGK BU8H semi-surface gap plugs have small side electrode not requiring gap adjustment pre-gap and are nearly immune to pre-ignition (knocking).

Worn or damaged spark plugs can lead to engine misfires, poor fuel economy, rough idling, difficulty starting the engine, and decreased engine performance, ultimately affecting your overall efficiency and potentially causing further damage if left ignored. It is essential to replace the spark plugs on your outboard engines every year or 300hr. These spark plugs are sold individually.

• NGK BU8H surface gap plugs feature a semi-surface discharge design to improve ignition and burn off any carbon before it can build up to foul the plug
  
• NGK Trivalent metal plating also provides superior anti-corrosion in the marine environment and anti-seizing for easier removal
• The copper core aids in heat removal to keep the spark plug operating efficiently
