Mercury – NGK LFR6A-11 V-Power Spark Plug | Ignition System Component | Nickel Alloy Electrode | 881284Q

Overview

Every smooth start begins long before the key turns. It starts with a spark plug you can rely on—one that fires clean, fires strong, and keeps your engine running the way it should. The NGK LFR6A-11 V-Power Spark Plug, offered as Mercury Marine part number 881284Q, is one of those quiet essentials that boaters come to trust. When you are easing away from the dock at sunrise or trimming up and running across open water, that steady, confident ignition makes all the difference. It is the kind of part that does its job so well, you barely think about it… and that is exactly the point.

Key Features

• “V”-cut center electrode improves ignitability by directing spark to the edge of the electrode
• Pure alumina silicate ceramic insulator provides exceptional strength and efficient heat transfer
• Trivalent metal plating resists corrosion in marine environments and prevents seizing
• Resistor-style design minimizes radio-frequency interference with onboard electronics
• Pre-gapped to manufacturer specifications for most applications (check and verify before installation)
• Built to meet Mercury Marine’s original equipment standards for reliability and consistency

Engine & Boat Compatibility

This Mercury Marine part is commonly used with:

• Select Mercury and Mariner outboard engines requiring NGK LFR6A-11 plugs
• Engines running electronic ignition systems that demand stable spark and reliable temperature control
• Boats of various types:
  • Center consoles
  • Runabouts
  • Pontoons
  • Fishing rigs
  • Family cruisers
  • Always match plug type to your engine’s owner’s manual for exact fit.

Performance & Practical Benefits

A good spark plug delivers more than a spark—it delivers confidence. With the NGK V-Power design, combustion begins with a clean, decisive arc that feels crisp on acceleration and steady at cruising speed. That “tight” and “responsive” throttle feel you notice when pulling away or pushing into chop often starts with proper ignition.

The corrosion-resistant plating keeps the threads clean, even after long months in salt air, making removal smoother and far less stressful. The ceramic insulator stands up to heat cycling, helping the plug stay stable through long afternoons of running, idling, and starting again. And because these plugs come ready to install—with only a quick gap check needed—you will find the maintenance simple, predictable, and satisfying.

Why Buy OEM

There is no guesswork with an OEM-approved spark plug.

• Mercury and NGK design these plugs to match the exact timing, temperature range, and fuel characteristics of your specific engine
• Better long-term performance and fewer misfires compared to generic aftermarket alternatives
• Maintains factory reliability and reduces the risk of damage from incorrect heat ranges or electrode design
• Creates a balanced ignition system that protects fuel economy, throttle response, and overall engine health

If you want a simple, right-the-first-time solution, OEM is always the smarter buy.
