Couldn't wait to install these

[This review was collected as part of a promotion.] I have felt noticeable changes every time I have used these spark plugs. I was time to put them in my truck. 2012 Tacoma wih a K&N cold air system and a Flowmaster exhaust. You cn feel the difference. Idle has smoothed out and throttle response seems better. I still need a tuner but things are good for now.
