Just to add, from my experiances working at a garage for 5 years, bosch plugs are terrible for ANY application. They by far have the highest rate of fouled out plugs no matter what car they're in. Regular copper plugs are the best for the neons ignition system and the price.

 

I have used Patinum, Platinum +4 and good 'ol Copper core Supers in many different cars with no trouble at all. But, just follow the recommended plugs for the application. Why go through th trouble of Getting Supers when you can get NGK, Champion, Autolites so easily. No big difference between them. Heck even though good 'ol AC plugs if ya want. Champions are cheap, work good so why bother.

 

Properly burning plugs should be tan in appearance. Your best off with the plain cheapy Champions, but if you really want to go with great expensive plugs you can get the Champion Iridiums. With as easy as it is to change plugs on the Neons you really should just get the plain Champions. You would be best off getting a set of MSD Super Conductor plug wires, they will make a noticeable difference in everything from how it sounds to throttle response to fuel mileage.
