Plain ole AC CR's. Set the gap at 32 and you'll probably be fine.


Unless your car is bone bone bone stock at which point plugs and gaps are the least of your worries.

Not sure if you have had any problems with the delco stuff but I had a fleet of trucks and always used AC/Delco and the quality has gone down hill in the last few years. They are not the Delco that once was so great. Everything from plugs, wires,o2 sensors, iac motors,filters.............Junk
