I just replaced all the plugs and coils... it's worth it because the car runs amazingly beautiful now.

if you changing one, you should probably change the other

You are suppose to do both. I replaced coils with global-automotive off of eBay and e3 plugs.. Awesome..

'03 LS V8 (54K on the "Clock")... changed all Coils and Plugs yesterday. Replaced Plugs with Motorcraft and the Coils with Borg Warner.

Of note, the Motrocraft Coils carry a 1 Year Warranty while the Borg Warner Coils carry a Lifetime Warranty.

I figured since the Motorcraft are the "Root Cause" of the Engine Performance Issues, why not use a "Better" Coil.

I will keep you all posted on the reliability of the Borg Warner Coils.

Switched the plugs to E3.54s shortly after I bought my 06. Runs beautifully

Excellent.. I have all good things to say about the e3s in my car..

There was a deal on them from Amazon a little while way. I threw 4 into my old spare Cavalier for giggles

I swear by them. I am throwing some in my Danger Ranger before winter..

This might be a stupid question, did E3 out compete Bosch in the multiple prong category or was Bosch never really in the game?
