Rating: (see review/s)

"1 out of 4 will miss at low speed while driving. I had to order an extra to replace a bad one that would misfire at low speeds. Pulstar s manufacturing quality control should do a better job of checking out going product." posted by: Bruce on July 21, 2014

"These spark plugs are impossible to screw in. The thread is good and can go into the engine but the bolt you have to use to screw it in has to be paper thin since the overal spark plug is too fat." posted by: Car person on February 9, 2011

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
  • Fit Note: 2 Of PN[0437S-4]
  • Plug Type: Resistor
  • Electrode Core Material: Copper
  • Anticipated Ship Out Time: 1-2 Business Days
  • Electrode Tip Material: Copper
  • Reach: 0.38 in.
