Bosch just don't last in Bonnevilles, who knows why. Get a Denso from RockAuto.com

you could replace both, but I'd start with the front one.

i bought a Bosch and it went bad 4 months later.. many others have had similar experiences. The few bucks you save isnt worth it if it keeps going bad.

There'* definitely a lot of truth to using Premium on this engine. Hell, I even noticed a big difference between using cheap premium gas and good premium gas (Cheap meaning places like Speedway, and good meaning places like Phillips or Shell). I always pump Shell or route 66 (Phillips) here in IL because I know they're clean gasolines, and I generally get 25 average highway fuel economy, which drops down to about 17 in the city under mild driving.
