Denso tt spark plugs

After binning the air intake for 60mm aluminium flexi pipe fed to air box from between radiator and o/s fog light, and closing the resonant chamber, its plugs and filters next. I'm thinking denso tt spark, with bosch air and oil filters? A school friend runs a 1.4 in Canada micra cup and swears by his set up, not that I'm rallying mine, just want a smoother power and torque band
