Free Spirits High Flow Air cleaner Kit for Triumph Thruxton 1200, Speed Twin, Bonneville T120, Bobber & Speedmaster 1200

This new solution has be developed to allow conical filter to work as they born for, narrow end in the front, large area in the rear, otherwise large surface would create a “vacuum effect” which is not a real improvement.

Our kit increases considerably the delivery of air to the motor; providing better performance and a cooler operating temperature.

This was possible thanks to our special 180 degree elbow.

The 50 mm diameter “180 degree elbow” made from stainless steel is produced by a unique patented process that allows the use of thin walled light weight construction (546 gr including looking-ring, while the SF Water proof filter is 128 gr).

The air flow increases considerably, but thanks to the bike's new "self learning" OEM engine software, our testing has shown there is no need to add costly maps or an additional fuel unit.

No need to remove original air-box

Engine temperature decreased of 10 degrees.

Attention !: With this kit, the original side panels must be shaved.

In addition, the new filter is WATER REPELLENT! so you don't need the classic "sock" to protect in case of rain.

Quick and easy to mount.

Ready for installation and complete with instructions.
As Free Spirits tradition all the modifications are reversible.

For this kit spare parts are available.
