Going with a open filter system to get all that comes with that setup means that the airbox gets removed. One of the good things that the airbox offered was heat protection from the engine sitting right under the carbs or throttle bodies, associated fuel and intake air of the engine. This heat shield provides radiant heat shielding placed in a similar way that the OE airbox did over the intake stubs. Its out of the way for serviceing the engine and while helping keep things cool.
NOTE: Picture shows the gromets in place, they are NOT included in the shield part. You will need to source them from a OE airbox, perhaps the one that you just removed. If you need gromets and don't have the OE parts, contact us and we can help get you the parts.
