I'm thinking about upgrading my plug wires and coil pack.

I'm beginning to think about upgrading the ignition wires and coil pack on my 06 X xls 4.0L. There are probably some good threads and posts on this subject already, but I figured I'd just ask the question in the meantime. I know there is a couple of product reviews over in that forum. Any suggestions are greatly appreciated. I'm also assuming that if I upgrade these, the vehicle will run a little better. I already have Autolite iridium XP-103 plugs I'm going to install. They made a big difference on my last 4.0L Explorer. Thanks.

For wires, I recommend Magnecore ( http://www.magnecor.com/ ).

And for a coil pack, take a look at http://www.explorerforum.com/forums/showthread.php?p=1535138#post1535138

What about on my 4.6l? performance increase or fuel economy at all worth the price you think?
