{"product_id":"ptr-carbon-intake-manifold-for-ls3-ls7-cathedral-port","title":"pTR Carbon Intake Manifold for LS3\/LS7\/Cathedral Port","description":"The Performance Design Carbon pTR Intake Manifold offers a lightweight, modular, and high-performance solution for LS-based engines. Its true tunnel ram architecture is constructed with a 5-layer carbon fiber plenum and a glass-filled nylon lower manifold, resulting in over 10 lbs of weight savings compared to traditional aluminum tunnel rams and improved thermal control to minimize heat soak.\n\nDesigned for versatility, this manifold features interchangeable velocity stacks with 6.5\", 8.0\", and 9.0\" runner lengths (6.5\" included), allowing you to tune the power curve to match your specific cam, heads, and exhaust setup. Longer runners generally favor midrange torque, while shorter runners provide more high-RPM power. The manifold is compatible with a 105mm throttle body with a standard LS bolt pattern and can be mounted in a reversible orientation for custom engine bays.\n\nFurther enhancing its adaptability, the Carbon pTR manifold includes provisions for short, mid, or tall injectors, two MAP sensor ports (front and back), and multiple vacuum ports (two 1\/4\" NPT and one 1\/2\" NPT) suitable for brake boosters or IAT sensors. It is also nitrous-ready, featuring 16 nozzle bosses on both sides of each runner. The billet aluminum throttle flange is available in anodized red or black. This intake is ideal for LS-based hot rods, drag builds, or street performance applications requiring significant airflow in a lightweight, heat-resistant package.","brand":"Performance Design","offers":[{"title":"Default Title","offer_id":52663242162488,"sku":"70515.03.00.BK","price":1099.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687523421.jpg?v=1784325270","url":"https:\/\/store.motormia.co\/products\/ptr-carbon-intake-manifold-for-ls3-ls7-cathedral-port","provider":"MOTORMIA","version":"1.0","type":"link"}
