Reducing 12 volts DC in a vehicle to 10.9 DC
A chassis-mount resistor is overkill, but if you really want to do it (convenient mounting holes?) then you can use the smallest rating available (probably 5W): (photo from Digikey).  



The closest standard values are 100\$\Omega\$ and 91\$\Omega\$, with 100\$\Omega\$ being more common. If you care about the difference between 100\$\Omega\$ and 94\$\Omega\$, you can add a 1/4-W resistor in parallel on top (put it in sleeving or shrink tubing). 

The value required for the parallel resistor is 1/(1/94-1/100) ~= 1.6K
