Installation Time: Less than 1 Hour
December 02, 2017
My vehicle is a 6 cylinder, but when making purchase, site specifies eight plugs, but only 6 shipped. Not that I needed the additional two plugs at this time, but I apparently paid for them. Otherwise, the vehicle fired up with no issue, but too early to tell what life expectancy will be. Mileage performance did not improve after 130,000 miles on original plugs.
