Installed these in my 2007 Chevy Avalanche and couldn't believe the throttle response. As soon as I stepped on the accelerator pedal I felt the difference as the truck jumped forward with a power increase - now that's what a V8 is supposed to feel like. Since then I've installed E3 spark plugs in all my vehicles with similar results. Whenever friends ask what spark plugs I recommend it's always E3 !!!
more power, reduced emissions, improved fuel efficiency, longer life, faster starts
