Pros: More power and MPG
Cons: Need color variations, dont recmnd E3 plugs.
" I installed on my wifes 1999 Bonneville along with Accel coil packs and OEM Delco Iridium plugs. The engine runs smoother accelerates quicker, also has a whine to it almost sounding like a SC 3.8. Mileage has improved by 2 to 3 MPG. Now getting 430+ on 1 tank, and I'm not gentle on this car. "
