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.
