Modified Glow Heads


Glow Head Modification - Glow heads used on the Cox TD 09, Cox TD 015,  Cox Conquest, and the Rossi 15 have been successfully modified to accept the Nelson plug by machining the matching recess in a stock glow head.  Performance has been on a par with the stock heads.  The engine owner must provide a new or used glow head for modification.  A burnt out head is perfectly acceptable as long as it is otherwise in good condition.

For the Cox 09 and 15 this reduces the cost of replacing a $12+ glow head with the far more reasonable cost of the Nelson plug.
