Just wondering if anyone new which sparkplug wires are good for a 2003 protege. Spark plugs also if u know.

The consensus seems to be to stick with the OEM copper plugs. Unless your spark plug wires are worn or faulty, changing them will make absolutely no difference in performance. Nevertheless, if you insist on changing them, both Magnecore and Sparco make replacement sets. My advice: save your money for mods that will make a difference.

changed my wires over to the bosch premium set. I consistently get 4 more miles per gallon. Needless to say, I am happy with my purchase.

IF this is true it makes you wonder why manufacturers who struggle for mpg improvements don't put these on at the factory.......oh well, glad you're happy.

dontcha know? the manufacturers don't put these snazzy parts on the cars cuz it's like...a liability or something... don't want the kiddos thinking they have hot rods, going too fast and killing themselves

well, I also changed the spark plugs, perhaps the new spark plugs had some of the effect too, but the old ones weren't in that bad of condition after 20k miles.
