Those are the ones I ordered! They should be in by today or tomorrow. I'll install them prob on Saturday and let you guys know the outcome.

 

I have a 04 blazer and had the P0300 code, rough idle and cutting out while driving it. I pulled all my plugs and seen they were all firing and replaced the plugs, wires, cap and rotor. even replaced the pick up module under the rotor and it solved my problem! I went from getting 10.5 mpg to 16.6 mpg
