Now available through M-Engineering, the perfect upgrade kit for your M838T! 

NOTE: This kit does require ProTuning.

The DWS1000 Upgraded Fuel System was born from a passion and created to fill a desperate need in the McLaren market. Up until now there was no way to increase the pump size for the McLaren 3.8L platform and once the limit of the factory fuel pumps was reached – that was it. With release of the McLaren 720s the earlier 3.8 platforms began falling to the wayside as there was no way to compete with the 720s factory brushless setup – until now!
