"I put these in my Vtwin motorcycle in November. In March the bike quit running. Took it to a dealer and all he had to do to get it running was put normal plugs in it. Hope nothing permanently damaged. Told a friend about it after the fact and he described the same trouble with his Chevy truck. His mechanic said they burn extra hot and mess up the computer sensors."posted by: GOC Sensei on March 12, 2014
"I replaced my 10 year old ----- Platinum +4 spark plugs which I was still getting 38 MPG highway with over 225k miles. After replacing with E3, my MPG fell to 32 MPG highway. Disappointed to say the least. I'm returning and going back to a new set of +4's."posted by: MJ on December 19, 2011view all 8 reviews

ACCEL U-GROOVE PERFORMANCE SPARK PLUG -- 14 mm thread size, 0.750 in. reach, 5/8 in. wrench diameter, heat range 4; Resistor type, copper electrode core/tip material, projected insulator type, gasket seat style; Constructed with a five-rib, highly purified Alumina insulator that prevents arcing at plug boot and provides superior strength and thermal conductivity, a copper-glass seal that bonds insulator to electrode for a gas-tight seal, and a copper-core center electrode that comes with nickel chrome sheel for superior electrical conductivity and maximum heat dissipation; Its electric heat seal ensures stable heat range for uniform performance; The plug's machine rolled threads guarantee trouble free installation and removal, protecting the expensive cylinder heads; Features a unique U-groove ground electrode developed to meet the demand for improved ignitability and increased fuel combustion resulting in less flame dissipation; Gives the flame a groove to grow in that creates 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; With 90-day Accel limited warranty.
