Benefits of our Splitter Tunnels:

The addition a splitter diffuser when placed on the front splitter will add a significant amount of front downforce to the front splitter. Our deisgn has the added effect of vortex generation, creating pockets of air circulation behind the diffusers, improving brake cooling.
