Finally: A complete carbon fiber plenum--top AND bottom--for the BMW S62. Made from multiple layers of pre-preg carbon fiber baked in an autoclave, hand trimmed, then fitted with billet aluminum connectors made in our machine shop. The Partee Racing S62 carbon fiber plenum bolts directly to the engine's throttle bodies with the provided bolts and gaskets, displacing the ridiculous stock rubber plenum gaskets and hose clamps and eliminating the need for expensive aluminum plenum plates (and with them, the gratuitous heat such plates retain). As a result of this clever design, plenum air volume is materially increased, air intake temperatures are materially reduced (especially when combined with the separately available under plenum heat exchanger delete kit), and both the appearance and the intake sound are outright intoxicating. Although our plenum fits with stock velocity stacks, it is best used with our separately available carbon fiber velocity stacks. Together, the combo is dyno proven to increase power in excess of 22whp!
