Spark Plug & Spark Plug Wire Gage

Recommended Posts

I have a 97 Lexus LS400. Does anyone know the OEM spark plug wire gage? I'd like to get the aftermarket wire set in the same diameter so I can re-use all the old hardware. Btw, which brand do you recommend for the wires? Also, is there a noticable improvement in performance when it comes to Iridium plugs such as the the NGK laser Iridium long life, NGK IX Iridium or just all hype? Would a regular platinum plugs be just fine? Thanks in advance.
