Any output on how great they are? Because ever since, I installed mine it chokes when I hit 4k-5k sometimes but yet that's only sometimes. I recall they're brand stinky new:shrug:
I have them on mine and noticed no difference at all. Nothing bad to say yet nothing to praise, except they do look good in my engine bay lol. I kept the stockers that I took off at 59k miles just in case.
Yea I have my stockers too. But when I replaced them with my msd the ruff idle went away. It doesnt always chokes just sometimes so im thinking it might not even be the coils. It actually pulls harder.
MY OEM ones sucked and the car ran like crap.
