VTT B58 (TU) HMM Delete Plate

Looking to build a race car with a B58 engine?
Doing a B58 swap and don’t want the complicated BMW Heat Management Module (HMM)?
Need a simple -16AN or -20AN line setup instead of the factory tangle?

If so, the VTT B58 (TU) HMM Delete Plate is exactly what you need.

This kit eliminates the bulky OEM Heat Management Module and replaces it with a clean billet block-off solution. The included rear water pump plug and hold-down bracket ensure proper sealing, while the modular -16ORB port allows you to run your choice of -16AN, -20AN, or any compatible fitting. Build your lines, run them to the radiator, add an inline thermostat if desired — and enjoy a vastly simplified, race-ready B58 cooling system.
