Worse mileage

Summit RacingSummit Racing Verified Purchase

Tried these in a 2004 Blazer with 4.3 liter V6. Highway mileage went from 20.2 with standard plugs, to 19.5 with the E3's.

Terrible product

Summit RacingSummit Racing Verified Purchase

These plugs caused more misfires than anything. The car actually ran rougher with these and threw codes every other day. I don't recommend putting these in your car. Stuck to OEM plugs and you'll be just fine.
