Are denso's close to the stock ac delco? I can get 2 for the price of 1 ac delco?

 

delphi or denso?

 

Got my denso's on and what a difference... Its like night and day idling and take off. It used to hesitate and kinda lag on take-off after being stopped for a sec or two... All day today it has not done that at all. It did however almost die when I put it in park but I believe thats the pcm learning that the 02's are working properly now.
