hello, we have found that the reason why my 2002 Corvette was jerks when driving, it was because the spark plug wires and spark plugs are in disrepair. I've been watching some plug wires sold in some websites and I'm not sure which one to buy. I've seen some for high performance and others not. there a difference? if I install a spark plug wires for high performance I can have engine problems due to the high temperature that can support or generate? you give me any advice on any particular brand? True, some cables may give 10 hp more engine? thank you very much as always!
