There are not many power upgrades available for the 2.7l Taco besides a turbo, but this is a reasonable and affordable way to make your truck feel more peppy. I changed out my spark plugs, installed these coils, as well as delete the airbox inside the fender(Basically free cold air intake) and it feels more attentive, higher smother revs, and just gives me more confidence that I might stand a chance at beating a pruis in a drag race.
