What are some recommendations for plugs for a 2010 5.3 Suburban? It has 200K miles but runs fine other than an occasional low speed miss.

 

ac delcos chevys run the best with the stock plugs they were manufactured with I'm not sure what type that truck takes because my trucks are 10 years older, call you local Chevy dealership parts department with last 8 of your vin and get those same plugs also replace your wires too I always get mine from summit.

 

You can also check your owners manual if you have it. Check the link, it lists many plugs to choose from. The iridiums are the best.
