{"product_id":"carbon-intake-manifold-2-665l-plenum","title":"Carbon Intake Manifold 2.665L Plenum","description":"The Pracworks Carbon Intake Manifold (HX-N-00-1) is engineered to significantly enhance the performance of Honda Civic Type R (FK2, FK8, FL5), DE5 Integra, and Accord (CV2) vehicles. This intake manifold is constructed from prepreg carbon fiber, offering superior thermal insulation compared to aluminum (40 times less thermally conductive), which helps minimize heat soak. It is paired with robust billet 6061-T6 flanges for durability and a precise fit.\n\nDesigned with a focus on mid to high RPM power gains, this manifold features long runners optimized for resonance tuning, a characteristic often lacking in stock Honda intake manifolds. Dyno testing indicates an increase of 25-30hp in the midrange and 10-15hp at peak power on a stock vehicle, with an almost 10% power increase from 3500 rpm onwards without requiring a tune. The plenum volume is specified at 2.665L, and the unit is rated as safe for boost pressures up to 70psi.\n\nInstallation is straightforward, designed as a direct plug-and-play component with an estimated time of 4 hours. It retains the stock Honda K20C1 throttle body bolt pattern and location, and accommodates a +2mm oversized throttle body with a 66mm inlet flange. The manifold is compatible with both left and right-hand drive configurations. Vacuum fittings similar in size to the stock Honda manifold are included. A port injection option is available for applications requiring additional fuel delivery, utilizing K20A injectors and including a Pracworks billet fuel rail.\n\nFor the Honda Accord CV2 (K20C4) application, an additional Accord CV2 Upgrade Kit is required, which includes a map sensor adapter, wiring harness extension, and vacuum plug. All Pracworks orders are made to order, with a typical lead time of 3-4 weeks before shipping.","brand":"Pracworks","offers":[{"title":"Default Title","offer_id":52663325983032,"sku":"HX-N-00-1","price":1650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687528019.jpg?v=1784325968","url":"https:\/\/store.motormia.co\/products\/carbon-intake-manifold-2-665l-plenum","provider":"MOTORMIA","version":"1.0","type":"link"}
