magnecore leads and better mpg

[jastutte]

hey all,

just figured the mpg on my stock 1996 discovery and having only changed the plug wires from stock to the 8mm magnecore wires my around town fuel mileage went from 11mpg to 13 mpg. still running the champion oe plugs and oe air filter. not great mileage but any improvement is nice. acceleration and idle "seem" a little smoother as well.

Sounds like the old ones were bad.

But either way glad to hear.

the old ones were only several months old. when i bought the rover after a couple of weeks i changed out the existing plugs and wires with the oe champions and stock 7mm wires. my mpg dropped right away. foolishly i had thrown away the plugs and wires i had pulled out and so could not check to see what they were. i think they were probably 8mm wires because they looked thicker than the 7mm i put in. the plugs were larger also and i remember switching sockets to pull the old plugs and put in the new ones. the plugs i pulled were champion as well but i don't know what #.

Too bad you didn't save one... it would be nice to have some record of what people have found.
