Ok so getting ready to replace all my plugs and wanted to know if I should go with oem, or one of the 4 prong plugs. I want a little more performance/mpg , well especially more mpg if these 4 prongs will help any?
Also when I check autozone for wire sets it shows them as coming with the distributor cap, so should I change the rotor as well?
Trying to get by as cheap as possible, without being TOO cheap on my cars performance.. Any tips or advice regarding this stuff would be greatly appreciated..
Got some issues here.. Went to take off distributor cap, it was so old and worn that it busted the plastic attachment to the ignition coil, and the rubber seal was dry rotted.
The coil was cracked upon further inspection. Will this be hard to replace as well?
Only misfiring sparkplugs worsen the MPG, working sparkplugs wont have any effect on mpg. 4 prong plugs dont do anything except increase plug change interval.

you should be able to get the coil from auto parts store or maybe ebay.. and the rubber seal is like and o-ring i found one for my car at checkers it came in a set of different size o rings
Happened to me as well. The grommets around the spark plug tubes are leaking. Its a pretty easy job, relatively inexpensive. Make sure when you tighten the nuts back down on the valve cover, don't overtighten, the little rubber bit on there can tear very easily. Its only a little to torque them down, on the matter of inch-pounds.

Just wanted to correct this since it came up, no point in letting members read bad information.
Plugs with a weak spark, or plugs with a wide gap, will ruin mileage. Plugs don't misfire. Two or Four prong plugs are mostly a gimmick, especially in a Corolla. Regular copper plugs will be the best performer, so don't buy the "better" ones they're trying to sell you, they're not better. Also, their change interval is longer in a correct application, but since they're wrong for a Corolla they will quickly become entrenched in carbon deposits. Knowing the 'why' is always the important part, not just memorizing what you've heard
