How to block the "heat" that greatly affects the performance of the engine? ・We have continued trials with all approaches from various possibilities. However, the method we chose to aim for "perfection" was to completely cut off the air introduction route from the engine room. This concept is actually normal (genuine). However, the normal state cannot be "perfect" because it is designed within various constraints. Without being influenced by that restriction, we gave top priority to efficiency, and gave the best performance and quality worthy of the name of an air intake specialist in all aspects such as intake air volume, rectification effect, materials, and fitting. The intake system is this "RAM AIR SYSTEM".

The specially designed carbon duct has a shape that completely blocks out hot air in the engine compartment. Directly introduces fresh air to lower and stabilize the intake air temperature. Achieves increased torque and power across the entire range from low rotation to high rotation. You can also enjoy the sporty intake sound. Installation is bolt-on using a special fitting adapter.
