If you buy a set of wires for your Viper along with the hi-temp socks, I will also give you a full set of Champion Spark Plugs (OEM Part# Only) when you call in directly to me to order. 502-419-0133. You will have to mention this promo to get it. I want to track the effectiveness of this offer. But this offer will end at the end of October. I have limited supply of spark plugs to give out so it's first come first serve. Thanks!
