ACCEL U-GROOVE PERFORMANCE HEADER PLUGS, SET OF 8

Accel U-Groove Spark Plugs are constructed with a highly purified Alumina insulator that prevents arcing at plug boot and provides superior strength and thermal conductivity. Copper-glass seal bonds insulator to electrode for a gas-tight seal, and copper-core center electrode that comes with nickel chrome sheel for superior electrical conductivity and maximum heat dissipation.

Features:
  • Electric heat seal ensures stable heat range for uniform performance
  • Machine rolled threads guarantee trouble free installation and removal, protecting the expensive cylinder heads
  • Unique U-groove ground electrode developed to meet the demand for improved ignitability and increased fuel combustion resulting in less flame dissipation
  • Grooves the flame to grow and create a larger flame front for a more complete combustion even in the case of lean air-fuel mixture
  • Produces greater firing energy without increasing spark plug gap and larger spark nucleus that stimulates faster combustion
  • Provides an increase in performance with improved throttle response, greater fuel efficiency, and reduced emissions


  • SKU#: A358197
  • Brand: Accel
  • Electrode Core Material: Copper
  • Plug Type: Resistor
  • Anticipated Ship Out Time: 1-2 Business Days
  • Electrode Tip Material: Copper
  • Reach: 0.38 in.
