General consensus over 5 different v6 forums: Bosch platinum +*insert number here* always cause cars to run worse. And all the rest of the crazy E9 whatever plugs are just a waste of your money.
99% of the 400-500-600 hp guys are using regular ngk/motorcraft/autolite copper plugs or irridums.
Wires are wires, but I've been through 3 sets of Livewires, and 2 SD coils.
As for gas mileage, your not going to gain anything... You might get back something from having a weak spark with OLD plugs but thats about it.

Grannatelli wires, Copper Core plugs, and a SD coil has worked perfectly for me a while now. Not to say ANY other product could or could not do better. 100% Motorcraft would be my second option if not for price and accessibility.

Unfortunately that's what I'm thinking too. I'm going to put it up on jack stands this weekend and check the u-joints and the motor mounts. I have a convertible so I'm scared ****less that the drive shaft is going to come undone in the front and flip the car when I'm on the interstate.

Why were they failing early?
