i dont think you will notice too much with spark plugs. the ones that comes with our S is good enough and dont need to be changed for 100k miles

 

there were some benefits that i personally felt with the Denso iridiums: the sudden drop in RPM to near stall, for example, when engine is hot and you step on the gas a bit and let it go without engaging the clutch, sort of disappeared. Spoon iridiums are Denso iridiums, btw.
