I have a 87 Iroc Tuned Port Injection 350.. I have read that many people have gone with AC Delco R45TS for Spark Plugs but was wondering what was a good brand and model for the wires? Also I have pretty much no experience with cars... Just wondering how hard of a job it would be to replace the spark plugs and wires... I was also thinking of doing the cap but not sure what is needed to do all this.. do you have to unbolt things or can the plugs and wires be replaced by without taking things out?

 

It should only take you a few hours to do. Just replace one plug and wire at a time. That way you wont get the wires mixed up. The cap and rotor only takes a screwdriver to replace too.

 

Some of the plugs are bit#*es to get at.
I use stock GM wires and have never had a problem.
