An air filter is your engine's only protection against the elements, and your stock filter isn't up to the task. Replace it with a Twin Air - the #1 filter system proven on motocross tracks around the world.

Twin Air's fused layers of open-pore foam and fine inner foam trap even the smallest particles-without restricting airflow.

Air Injection Block Off Plate, Driven Billet

CRF250L '13 - '21 CRF250L Rally '17 - '21
$46.95

Driven engine block off plates will stop the annoying and possibly damaging backfires from occurring while allowing you to remove a few pounds in associated valves and hoses from your bike. On late model EFI bikes with 02 sensors, ESPECIALLY when using Dynojet's Power Commander V with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your 02 sensor's values and make it impossible to get a correct tune.

Air-box Cover Hardware

DR650 '96 - '21
$8.95

The screws and nuts that hold the Air-box Cover on have a habit of jumping out of the air-box and running away. No idea where they go, but it is far! These cannot be purchased separately from Suzuki but we found some that are perfect replacements. This little kit includes four screws and the square nuts that go into the air-box. We recommend that you put a dab of silicone or something to hold the nuts in so they don't jump ship like the other ones did.

Air-box Seal

TW200 '87 - '21
$6.95

Yamaha uses this seal material in many places on several motorcycles. It is like weatherstripping and is used to seal up the edges in the TW200 air-box. It seals up the air-box so that water and grime can't enter the air-box from the side. Ensures that air entering the box comes from up under the seat.
