With new coils and new wires my car is running a whole lot better. My misefires have went away. No more drop in voltage at idle. Time to drop the subs back in.

Sort of, I got the ones from Jegs. They are rated for Higher voltage 45,000 volts. The stock ones only run 40k. I do not think that makes much of a difference though.

You should notice a slight increase in midrange hp. Especially with good performance wires. Mine was noticeable.

My car has been running so bad lately with the the messed up coils and wires, that even stock would have been 100x better. But I do know what you mean, I am pretty sure I felt the power. It is not so much a increase in power, as more of something is happening quicker, in the engine. Must be the coils.

How much did everything end up costing you.

I had a bad coil as well, but I was running Jseabert'* stockers when the MSD'* came in, so I had a good comparison. It was noticeable. I'm betting that'* why the 'seat of the pants dyno' is telling you.

Coils should run about $120 for all three, plus wires (about $50 more). I wouldn't waste my time on the MSD coils without putting a good set of Taylors or MSD wires on there at the same time.

Jegs for the coils, you need the 8224'*, and www.grandprixstore.com for the best price on the Taylor Spiro-Pro wires that I've ever seen.

My jegs generic branded ones cost $99 for all 3. Some msd ones should cost about $120. The wires I have found can range in price from $20 (do not buy), to about $120. Be sure to buy ones for a minimum of $30, go even better if you can. I cannot stress how much cheap wires suck. They lasted me a whole 2 months.
