Direct replacement for old or broken stock spark plug caps.

Spark plug caps contain a resistor that can burn out with age. Fresh caps ensure your motor gets a strong spark.

• Sold in pairs.
• Adaptable thread size
• 5k Ohm
• Allowable wire diameter 7 mm-8 mm
• 120° elbow
• Spark Plug Resistor Cover - 10/12mm

Iridium spark plugs are made with premium quality materials.

Iridium plugs last longer than standard ones, meaning you won't have to replace them as often.

• The ultimate in the evolution of spark plug technology and performance from an industry leader
• The iridium electrode is 25% smaller than a platinum electrode, and it's just 1/4 the size of a conventional nickel electrode
• Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
• Metal shell plating has enhanced anti corrosion qualities

Sold individually, unless otherwise stated.

E3 Resistor Spark Plugs

The unique design of the electrode maximizes the power generated by the spark plug through Diamond Fire technology. This electrode combines advanced performance capabilities and innovative technology to enhance the shape of the flame kernel. Consequently, the flame front ignites the air/fuel mixture more rapidly, accelerates heat transfer into the combustion chamber, and creates a more concentrated pressure front, facilitating a quicker pressure rise during the cylinder power stroke. The outcome is a more efficient combustion process and improved engine performance, making this a truly premium spark plug.

Keep your motor running right with fresh spark plugs!

NGK is one of the world's largest manufacturer of spark plugs, whose products are used as original equipment (OE) on countless motorcycle and automobile models.

• High-quality materials and superior construction for serious power and reliability
  • Pure alumina silicate ceramic insulator provides high strength and better heat transfer
  • Deep-seated copper core for a wider heat range
  • Nickel alloy tip for longer life
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
• Choosing the right high-quality plugs prevents fouling from running too cool and preignition from running too hot
• NGK plugs available for almost every application and riding style

Keep your motor running right with a fresh plug.

A Dual Electrode spark plug will last longer than a single electrode plug because the wear is shared between the electrodes.

Hardened chrome vanadium steel with built in rubber insert to hold spark plug steady.

Thin wall bi-hex sockets designed to access narrow spark plug holes.

• Use with 3/8" drive ratchet or wrench
• Choose the one that fits your spark plug size:  14mm, 16mm, 18mm, or 21mm.

This high quality socket from Motion Pro, is specifically designed to reach into the very small, deep space where the spark plug of the XR hides.

Normal sockets simply won't work in this case.
