This glow plug adapter head for McCoy and Testors .049 is designed as a stock replacement. The turbo type glow plug allows for optimum combustion chamber design and seal. This results in a plug adapter that doesn’t give up power the way many designs do. As a stock replacement this head should make the same or just a little more power than stock and will not stress the components. Use a standard Cox wrench for installation. No gasket in used in these engines.
Kamtechnik Turbo heads accept “Turbo” style taper seat glow plugs to optimize combustion chamber shape. Glow plug is not included. Turbo type glow plugs are available in a wide selection of heat range for tuning. Suitable plugs for .049 are OS P3, P4, P5, RP6 and other makes in the hot to medium range.
Standard 1/4″-32 plugs are not compatible!
Made in the USA!
