F/S .667 UrS4/S6 5th gear
 

I have a few new .667 5th gearsets fitting the 5 speed transmissions as found on the ur S4/S6 cars. Cost is $625.00 with shipping and installation instructions which is $100 bucks off our website price. A few of my customers report an increase in highway fuel economy of 3-4 miles per gallon using these gears. Can be installed with the transmission in the car.
