Much easier access than an LS motor3)old plugs at 1600 miles burned with clean electrodes4)I did not disconnect the battery or reboot the ECUimpressions - a must do. The engine is much smoother and no more stutter on acceleration. Idle is smoother as well. This is a must do IMHO, truck should come from the factory with these plugs</blockquote>
