        Comments about Autolite Single Platinum Spark Plug:

        IMHO i don't like this brand as many others don't, but if your in a bind and don't have alot of money they will do for a few months until you gather up some funds and get a more expensive better name brand spark plug. The price is cheap for a reason, not saying the most expensive spark plug is the best one either because the best spark plug is the same spark plug your car was manufactured with and with Hyundai most have a NGK plug in it from the factory. Depends on ur car if its copper, platinum or whatever and thats the plug that should be installed for best results. A-men LoL
