Brand new and boxed.
Fits 14mm spark plug hole.A glass topped spark plug which enables the fuel/air mixture to be set by looking directly into the combustion chamber at the combustion colour.This varies in much the same way that a bunsen burner flame changes colour dependant on the gas/air ratio.By setting the colour to blue the engine will operate at maximum efficiency giving greater power and/or improved fuel economy.I have adaptors for 10,12mm and 18mm spark plug holes to allow the 14mm colortune to be used in motorcycle,mower and snowmobles etc as well as larger vintage and vetran cars..Made by Gunson the colortune is ideal for older cars with adjustable jet carburettors.(SU Stromberg Amal etc).Kit consists of colortune plug,adaptor for spark plug high tension lead,cleaner, brush and shield.I have lots of other tools for older cars and bikes including wrenches in Whitworth,BSF,BA and AF sizes,please have a look.
