I drive a 2007 Chevy Silverado LS V-8 5.3L|||yes then you might have to re calibrate to computer|||nope ! it might run better but you won,t get anymore horsepower.|||No, spark plugs just ignite the fuel.. and injectors inject the fuel,
theirs nothing speedy about either, unless you get stronger injectors.
Which you shouldnt unless you need to.|||on all levels, no i do not think that you will see any performance increase UNLESS the old stuff was just that worn out. the injector pulse width will correct for the injector increase, and the plugs are the last in the line of simple electronics.electrons only want to do as much as they have to (lazy just like the rest of us)
