I just got these plugs on discount and wonder if they are any good to go in my 5.3.
I also got ACDelco wires

very good plugs but your still wasting your money
it doesnt hurt to use the expensive but the ac delcos for example i think are half the cost and work just as good as the expensive ones
never buy the expensive spark plugs, never buy a cold air intakes, never run superunleaded if the manual says regular
all of the above increase performace by exacly 0% and are marketed to increase HP but do nothing but increase the manufacterers profits

Man I put these in and got hit with P0300 code. Smh

Clear the code and run it for a while. P0300 is a miss fire, but dosent indicate which cylinder. I'll bet it dosent re-appear.

I think it was spark plug #1 because I took it out to check the gap and it broke. So I replaced it now no lights are on and no hesitation.
I'll report back

Take a look at this link and you will see that cold air intakes do in fact add HP and torque. 9 HP and 8 TQ isn`t much but it`s certainly not 0%

Another uninformed member blowing smoke out his ass. If people read as much as the shit they type they might learn something and not sound so ignorant.
