I would recommend the OEM spark plugs, AC/Delco. Excellent plugs.
For a 2002 Chevrolet Trailblazer, it is recommended to use AC Delco Professional Iridium spark plugs (part number 41-101) or equivalent. These plugs provide better performance and longevity compared to standard copper plugs. It's essential to check the vehicle's manual for specific requirements and ensure proper gap settings during installation.
what kind of car?

AWSF-32C is the stock plugs
I just put Denso Iridium spark plugs in mine (part #IK16): http://www.densoiridium.com/index.php But these are by no means the only kind of spark plugs you can use. Before these I had SplitFire Platinum.
You must buy BOSCH sparkplugs for this vehicle.
Check the Vehicle Emission Control Information ( VECI ) decal in the front of your engine compartment , it will show what kind of spark plugs to use and the spark plug gap

All depends on what kind of spark plugs you have. It could either be 30,000 miles or 150,000 miles.
