You don't need "performance" sparg plug wires unless you have other mods that need the support like a huge stereo or a highly tuned engine with a stand alone ignition system.
Call your local car dealership and talk to the parts department. Get the prices on the dizzy cap and plug wires from them and compare to the local auto parts store. If you really want to save money, and you can at the auto parts store, then do. If you want quality, then get the oem parts (from the dealership) and they will work great.
If you still want to check prices on other wires, check the Corolla sticky for a big list of online vendors where you can find prices.
