i gotta 98 gs400 and i had stock densos in my car for many miles..when i changed them out i put in NGK IX iridiums and i love it . .. .most people would say torque masters but thats way over-rated !!! NGK plugs are great, but they are pricey ...but good thing my uncle works at napa and i get each IX plug for 3.50

Copper.... best performing of the bunch... too bad they don't last nearly as long... Plus they are cheapppppppp.... Seriously though, if you don't mind the labor every 20k miles or so (they claim 30k), the copper are overall a better performing plug than the iridium / platinums, and they are less than $2 each...

^^^ coppers don't last 20k miles. Even 10k is stretching it.

Okay 2nd question. Stick with OEM from Lexus dealership spark plug wires, or would AC Delco brand work fine?

Honestly, when it comes to wires, i would stick with OEM wires. I have seen the fitment of the aftermarket wires, and they dont always fit right. They are usually decent quality, but id stick with OEM.
