The original Etel-Tuning Transmission Sand is a must have for every vehicle. The sand generates very high friction in the gearbox, which increases its efficiency.
The different color options result in grain sizes:
– Yellow Transmission Sand: 0.05 – 0.3mm
– Red Transmission Sand: 0.25 – 0.5mm
– Blue Transmission Sand: 0.4 – 0.8mm
– Green Transmission Sand: 0.7 – 1.1mm
– Black Transmission Sand: 0.1 – 10mm
Contact your vehicle manufacturer or Etel-Tuning if you need help choosing the right color and amount for your vehicle.
