High engine temps are the biggest threat to motor speed and power. Race your Hummer H1 as hard as you'd like - our transmission cooling parts keep your fluids at a lower temperature. In the end you can be capable to tear up the tracks, pull bigger trailers, and get the big jobs done.
If you're stuck with lacking power and torque, high heat is often the cause. You will pull even more out of your H1's drivetrain, with cooler transmission fuild, oil, or fuel. The best thing is, buy H1 oil cooling parts at competitive prices and with absolutely free shipping at AAG.
