Champion Spark Plug Accessories

Champion Spark Plug Accessories: Precision Tools from a Century-Old Leader

When it comes to ignition system maintenance, the spark plug itself is only part of the story. Getting the installation right — with precise electrode gaps, properly seated boots, and intact wiring — is just as important as choosing the right plug. That's where Champion spark plug accessories come in, bringing the same engineering discipline to support tools and components that has defined the brand since 1907.

Spark plug accessories from Champion are designed to complement the brand's extensive plug lineup and work reliably across a wide range of automotive, powersport, marine, and small-engine applications. Whether you're a seasoned technician or a first-time DIYer tackling a tune-up, having the right accessories on hand ensures the job is done correctly the first time.

Gap Gauges and Setting Tools

One of Champion's most recognized accessory offerings is their line of spark plug gap gauges. The classic CT-481 taper gap gauge is a compact, silver-dollar-style tool that measures electrode gaps in both inch and millimeter increments, ranging from 0.020" to 0.100" (0.6–2.4 mm). Its simple, durable design makes it a staple in any toolbox or glove compartment.

For more precise gapping needs — particularly with fine-wire iridium and platinum plugs — Champion offers the fine wire gap gauge (SPT64). Housed in a high-impact red plastic case, this retractable tool includes multiple sets of go/no-go wire gauges in a range of sizes, making it ideal for verifying exact clearances on today's more sensitive electrode materials.

Champion also produces dedicated gap setting tools designed for bench or vice mounting, engineered to allow simultaneous adjustment of multiple ground electrode prongs without disturbing the spacing gauge — a professional-grade solution trusted in automotive and aviation maintenance alike.

Spark Plug Wires and Boots

Champion's accessory catalog extends to ignition wire sets as well. Their wire sets use application-specific boots and terminals, with insulation technology that strategically combines rubber, silicone, and polyethylene materials to minimize electrical loss and maximize spark energy delivery to the combustion chamber. These are engineered to pair directly with Champion's plug families, ensuring low-resistance connections and reliable suppression of radio frequency interference.
