I also read of something similar on the Edmunds Crossfire Forum, I am also kinda interested in this item and the Magnacor wires. Here is the post from that forum:
#653 of 730 Things Worth Trying... by rdotson Jul 24, 2005 (7:00 pm)

About six weeks ago, I bought a "new" '04 Crossfire (6 speed) and, so far, I've enjoyed this little car as much (or more) than anything I've owned over the years (the list includes several Bentleys, a Rolls, a Maserati, a Citroen, Mustangs, Lincolns, and many others)! For a purchase price of $23,800, there is NOTHING that comes close in value!
Being the inveterate tinkerer that I am with all my vehicles, I immediately began to look for "bolt on" accessories to give just a little more "oomph" (though, stock is pretty impressive!) and to date have done three things:
1) K&N Filters (takes two #33-2290) - order from anywhere!
2) InaZma HyperVoltage System (mfgd by Sun of Japan) (available from link title- they have been just super to deal with - responsive, helpful, etc.- go to the website and you can read about the system). A friend of mine with an '04 Mazda RX8 added one to her car with similar results - a bit more torque, smoother and faster accelerator response!
3) MagneCor KV85 Competition Ignition Wires - part #65211(link title- custom made per order) - great service!
All of these items have improved the performance of my CF without question! The biggest effect came with the installation of #2 (parts were installed a few days to weeks apart in the order noted above).
To DIEHL: Check out link title - they carry some nice aftermarket parts (cosmetic/appearance and performance) - they list a chrome grill for the CF which looks great! I have NOT ordered from them yet, so cannot speak to their service...
I have NO financial interest in any of these companies (darn it)!
Also here is a link to the products on eautoworks.
