Great product, great price!!
I was on the fence about trying a new brand other then my normal msd coils, but I read some good reviews on company, my friend had purchased them 7 mnths ago and is still very happy with there performance. I received my a couple of hours ago and I've already got them on! So far extremely pleased so far!!

Good for the price.
It was the right fit for my car especially from 2004 car model. Way cheaper getting it from here than a getting it from a shop that would cost you more.
