has anyone on this site used em.

whats good/ bad about em?

are they just plug and go?

 

yes, Delcos are original equipment in our cars, and you should stick with them

 

someone told me to buy these and could help with my misfiring problem.

why would i buy em when they are in the car from the start

 

AC Delco is only good if u have stock cobalt. I just went through a fight with 2 dealerships because i had NGK BkR7e 1 Step Colder and one of them came loose cuz it wasnt torqued down all the way...dealership put AC Delco plugs in the car and because of the heat from them it melted the oring on the valve gasket causing oil to flow into my spark plug bay....Get NGK BKR7e 1 Step Colder plugs

 

Depending on what year your car is. Yes they could very well be the plugs that came in your car. It seems that there was a change from NGK's to AC Delco plugs in the part listings sometime in the 07MY. The NGK's are no longer carried by GM. They will recommend you use the AC Delco's.

 

i wonder whats in my 2.2...wait nevermind its a 2.2 its probably got delcos

 

Like i said, AC Delco is ment for stock or possibly gm stage 2...anything else they are useless

 

Please read my sig. This is a performance or service related question, therefore I'm moving it.
