ACCEL 8170 U-Groove Standard Blister-Pak Spark Plug - Pack of 8

Product Review

The Accel U-Groove Performance Spark Plugs produce a larger spark for more power at high RPMs. This is an unique specially design ground electrode, that was developed to meet the demand for improved ignitability and increased fuel combustion. It features a copper-core center electrode with nickel chrome sheel provides electrical conductivity and maximum heat dissipation. The U-Groove ground electrode also has a larger spark nucleus, which stimulates faster combustion, producing more, power for higher RPM's of longer duration. The result is an increase in performance with improved throttle response and, due to a more complete burn, greater fuel efficiency and reduced emissions. It has a five-ribe, highly purified Alumina insulator provides superior strength and thermal conductivity that prevents arcing at plug boot. With the U-Groove ground electrode, firing can be greatly improved without increasing the spark gap.
