Engineered to maintain fundamental OEM styling while adding internal space to allow for more efficient M3 GT style velocity stacks, our intake plenum makes no sacrifices for optimal performance, aesthetics, or sound.
We achieve this by starting with a one-piece design. Although not the easiest design to manufacture, the design minimizes failure points caused by the easier conventional method of bonding two halves together, increases the overall rigidity of the component by ensuring continuous load transfer through carbon fibers with no perceptible break, and decreases overall weight.”
Made from aerospace quality pre-preg carbon fiber baked in our autoclave, then clear-coated and hand-finished with billet aluminum fittings, all in Partee Racing’s Danville, Virginia shop.
Offered initially at the introductory price of only $1850.00 in gloss, and $1950.00 in matte. Solid topped version with no Lexan offered at $1800.00 in gloss and $1900.00 in matte.
