■ Details
This product is an air filter kit that can be attached directly to the normal throttle body by removing the normal air cleaner box.
* For cars equipped

with down mufflers By attaching our down muffler to a normal engine car and attaching this product, it is possible to increase the output in the higher rotation range than when replacing the muffler.
Based on the test data, the kit comes with a connecting tube for the normal throttle body that calculates the appropriate length and positional relationship without affecting the inhalation effect.

Since the air filter body has a blow-by union, it can be connected to the blow-by hose using the supplied union or hose.
The kit includes a sensor stay that can fix the sensor installed in the normal air cleaner box.

Can be installed simultaneously with our R. side cover and oil catch tank kit.
■ Installation of our oil cooler kit to fix the oil cooler body to the frame is possible.
