Ok... After installing a new distributor cap and rotor tonight, I have decided to replace the plugs on my van. I have a 2001, Chevy Express (Explorer conversion), with 50,000 miles, and appears to have the original spark plugs... Anyway, should I go with the AC Delco brand, or is there something as good/better??? Let me know what you think, and thank you in advance!

 

If you do a search you will find 98% or more of the members on this site recommend AC Delco plugs only.

 

The best way to go is with the factory stock spark plugs.
Most people get into trouble with fancy aftermarket plugs or different brand (equivalent) and start getting service engine light and driveability problems afterward.
At my repair shop , we've seen problems with off brand PCV valves also goofing up the computers inputs and making sensors read a bit "odd" so stick with the factory recommended parts.
Can't go wrong if you do it right.....

Thanks for the follow ups guys! I went with the AC Delco brand so I will sleep better at night! And by the way, who was the ***hole who buried the back two plugs!!! The job would have taken 30 minutes, but those back 2 plugs...
