The Tamiya 41009 oversized heat sink head is aimed at drivers who demand consistent engine temperatures from their TGX FS-15. The larger heat sink surface helps move heat away faster, supporting repeatable performance across heats and practice sessions.
By enlarging the fin area and increasing exposed metal, the Tamiya 41009 enhances passive cooling without altering the engine's internal layout. That makes it a practical upgrade for competitors who need reliable thermal management.
Fit the Tamiya 41009 when you want a simple, durable way to control engine temperature and keep your TGX running consistently lap after lap.
