Colder plug help!
Hey all,
I was just given a set of Denso Iridium IT20 plugs. They are -1 heat range from stock plugs. Will they hurt the performance or damage the engine in any way now that I am not running a power adder  Or should I just save them till later and keep running the stock plugs.Thanks
