• ACCEL 0416S-4 Shorty Copper Core Spark Plug, (Pack of 4)

    ACCEL's improved copper core spark plugs have a conventional ground electrode which is designed to unshroud the center electrode which helps the spark for a better ignition. This allows the flame to expand more rapidly in the chamber which helps in producing more horsepower and reduces misfire. Improves throttle response, fuel economy and less fouling. Purified alumina insulator prevents arcing. Machine rolled threads protect heads. Shorty configuration is 3/16 inch to 3/8 inch shorter depending on the application to gain critical air gap space between the spark plug boot and the exhaust manifold or header tube. This helps eliminate burning the spark plug boot or dimpling the header tube. The shorter spark plug length also can make it easier to install and remove the spark plugs in certain applications where there is not a lot of room to fit a socket or move a wrench around.

  • ACCEL 8196 U-Groove Resistor Spark Plug 14mm Thread .708 in. Reach Heat Range 6 8 Pack U-Groove Resistor Spark Plug

    ACCEL silver tip racing plugs have better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression engines. Silver is an element with the most free electrons, and is the best electrical and thermal conductor of all metals. Better than gold, copper and many times better than Iridium. The ACCEL silver tip racing plugs have a fine wire center electrode (not just the tip), which gives more room for the insulator between the center electrode and spark plug shell. More insulation results in a more durable spark plug with high dielectric strength, the most important spark plug parameter in forced induction applications. ACCEL silver tip racing plugs provide powerful spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and supreme anti-fouling resistance under light load operation. Fuel compatible. Plugs can be used with LPG, E85, methanol and ethanol injection, High compression, and high RPM engines. Shorty silver plugs, all the benefits of the ACCEL Shorty plug but all the benefits of the silver tip plugs.

  • ACCEL ACC 578C1-4 578C1-4 Copper Spark Plug 1 Range Colder Than PN[578] 4 Pack Copper Spark Plug

    ACCEL U-Groove performance spark plugs have a patented U-shaped ground electrode that produces a double wide, hotter spark to ignite standard or even the highest compression engines. The sintered alumina heavy-duty five rib insulator eliminates flashover and overheating that occurs with high performance and long range applications. ACCEL U-Groove spark plugs use the purest copper/nickel alloy electrode to produce a broad heat range that is highly foul resistant and dissipates heat better than any other material. Years of racing and street performance research has proven that ACCEL U-Groove spark plugs deliver the hottest spark and the highest performance of any spark plug available.
