Do u recommend that i install a Torque Master Spark Plug ??

Yes

the spark plug sparks. the spark ignites the fuel/air mixture in the combustion chamber. the combustion pushes the piston. that's what gives your car power. "premium" spark plugs claim to spark every time, saying that regular spark plugs misfire from time to time. i don't know offhand what brand lexus uses OEM, but i would assume it's a quality part. so i personally wouldn't bother with a plug that costs two or four times as much.

Generally Lexus uses Nippo/NGK Iridium plugs-good plugs. The TM plugs were not available in what I wanted the last I checked for this car. Try Carson.com. Some have claimed that they work great (not sure if they replaced wore plugs with these) and others claim a waste of money.
I run the NGK's myself as I have noticed they seem to wear longer vs the Nippo's. Just my preference.
