Just uprated my plugs to a set of competition 10.5\'s all round courtesy of Clive at MRP...
took it for a little tear, car is running sweeeeeet :Giggle
just thought id share it :3gears-rh
Are these plugs for track days and fast road use or are they at the right temperature range for day to day driving?
i use my FD for almost day to day driving (2-3 times a week) and have done me well as fast road use. At least with 10\'s or 10.5\'s all round you can switch the plugs over between the top and bottom rotors to get the most life out of them...
if i had 500bhp this wouldd be this first thing i\' change..
my car is pretty much stock and im driving it on 11,5 iridium spar kplugs - car runs smoother then ever - all u need to do to be able to use colder plugs is just to give it a good tragging (which i do :p)
i was running to 9\'s and two 10\'s and car ran well, but its now even smoother with the 10.5\'s all round...just toyed with an M3 on my way home...lovely, he couldnt see where i went
