Well my car has 95k miles on it and i've already changed out the plugs and wires on it. I'm thinking about changing my coil packs b/c i can detect a slight miss in the engine when under load. I just did a PI head swap and i had the miss before and after the swap. I'm going to change my coil packs and then my injectors if i'm still having problems. What are ya'lls opinion on the screamin deamon coil packs? Will I feel a difference in performance, or will it pretty much feel like the stock coil packs. If anyone has had these installed for a while please let me know how well they hold up.

Thanks,
Jake

I swapped mine out but the difference is debatable. I 'feel' like it made a difference but I have no proof. I opened up the spark plug gap to .062 mm and the engine runs smooth. It also bumped my gas mileage up from 21 to 23 mpg on the highway. I do have that proof. It was worth it to me just for the increase in mpg.

Yes do not get the wires!! I sent mine back. They don't have the double clip on the head of the wires to clip onto the coil pack. VERY VERY bad design. Plus that covering gets really dirty easy. They took them back no questions asked. I have the Taylor 10.5mm they work great!

I think if that even if the only things i get out of it is a smoother running engine and better gas milage, they are still worth it. Thanks for the responses guys and if anyone has them and has had negative experiences with them please speak up.
