Install this Thunder Stroke ® performance Air box Kit and you boost the performance of your Indian® Motorcycle®, create more legroom on the left side of the engine, and enhance the style of the Thunder Stroke ® 111 V-Twin.
This intake kit completely replaces the stock air box and gives the engine a 1” narrower profile on the left side.
The “Big Sucker” intake lets the engine “inhale” more freely for a slight performance gain, and it enhances throttle response.
The air filter element is removable and washable to ensure consistently outstanding performance.
The black air box cover adds great style and features the Indian Motorcycle® script logo and a machined perimeter.

As we receive repeated requests for a rainsock, here´s the answer of the filter manufacturer:
That system is made by us and comes with our New Black Synthetic Style Filter.
Those are Water Resistant so you can run it in the Rain. No Rain Sock is needed, and the Maintenance is very easy.
You just use Dish Soap and water to clean (No Filter Cleaner, No Filter Oil).
Not legal in EU.
