New 12mm Rotor and Head for VW TDI (Jetta, Golf, Passat, Beetle). Upgrading to a 12mm rotor from a 10mm rotor will increase your maximum fuel flow. More fuel means more horsepower. Includes the seal that goes between the pump and the head/rotor.
I highly recommend replacing your stock size nozzles with larger nozzles (along with this rotor) if you are looking to increase your fuel flow.
The dimension from the end of the head to the rotor needs to be checked, when the camplate is not compressing the rotor springs. This dimension needs to be around 3.7mm.
We had a dissatisfied customer send a pump with a broken rotor back to us, and we found that the rotor was hitting the timing plug. Unfortunatly, there are a few different camplates that came in the TDI pumps, so this dimension needs to be set properly.
Comes complete with springs as Pictured.
