ENHANCED IGNITION
The small diameter Iridium tip focuses the electrical energy around the centre electrode, resulting in more efficient ignition.
BETTER ACCELERATION
Reduction of 0.7 seconds in time to accelerate from 20-60mph.
FASTER STARTING & SMOOTHER RUNNING
With the high ignitability of the NGK Iridium IX Spark Plug, your engine will start up quickly and run smoothly even on cold and damp mornings.
LONGER LIFE
The 0.6mm Iridium electrode gives continuous reliability over a long period.
BETTER FUEL CONSUMPTION
The excellent ignitability of NGK Iridium IX Spark Plugs gives very high combustion efficiency, resulting in more miles per gallon.
I agree, have put them in mine after reading of problems with the Bosch ones i had fitted (they were new) bought them online from the Spark Plug Company, good price and quick delivery www.sparkplugs.co.uk
Tried Halfords and they list the wrong ones for the MGF (MPI)
I have heard that some rare metal plugs aren't suited to the wasted spark systems as 2 of the plugs are reverse biased and it leads to premature wear.
Haven't seen it in mine yet.
