E3 Resistor Spark Plugs

• Unique electrode shape maximizes the power created by the spark plug – Diamond Fire technology
• Electrode is a combination of performance and technology that results in an improved flame kernel shape
• This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
• The result is more complete combustion and an improvement in engine performance
• A truly premium performance plug
• Sold individually, unless otherwise stated.

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

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

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.

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.

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.

Fits 3/8" square drive and hex drive, 14mm, 16mm, 18mm, 21mm.

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.
