Glass reinforced nylon lower and carbon fiber upper shell combine for lightweight, strong and heat resistant performance. Offering unique modular velocity stacks enabling 6.5 – 9” runners, multiple accessory port and sensor options along with other custom features, this manifold offers easy configuring for any cathedral port hot rod setup.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eShipping with the longer runner, optional velocity stacks offer different lengths. Tuning of the intake runner length to match the cam, head and exhaust combo gives the ultimate way to optimize your engine’s power curve. Shorter runners support high RPM drag applications or longer runners for improved torque in the mid-range. Mixing lengths can help smooth out the torque curve.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe plenum is constructed from high strength carbon fiber with high temp epoxy for improved strength to weight ratio and reduced heat soak to the fresh air charge. The polymer lower runner pack resists heat soak from the heads and houses all ports\/sensors hidden in the valley. The combination of materials offers a 10 lb weight savings over competitive aluminum tunnel ram manifolds.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: Due to height, hood clearance may be a concern on many applications.  \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications \u0026amp; Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor cathedral port cylinder heads\u003c\/li\u003e\n\u003cli\u003eModular velocity stacks for 6.5”, 8.0” and 9.0” runner lengths\u003c\/li\u003e\n\u003cli\u003eRaised velocity stack runner entries\u003c\/li\u003e\n\u003cli\u003ePA6GF30 Glass filled nylon lower manifold for light weight and low heat soak\u003c\/li\u003e\n\u003cli\u003eCarbon fiber plenum with 5 layers of carbon and foam core flange\u003c\/li\u003e\n\u003cli\u003e105mm forward facing throttle body flange accepts 90-105mm throttle body\u003c\/li\u003e\n\u003cli\u003eTwo MAP sensor locations (front and back)\u003c\/li\u003e\n\u003cli\u003eTwo 1\/4 NPT ports for PCV, purge solenoid, etc.\u003c\/li\u003e\n\u003cli\u003eOne 1\/2 NPT port for brake booster or IAT\u003c\/li\u003e\n\u003cli\u003ePlenum volume: 10-11.4L (depending on velocity stack used)\u003c\/li\u003e\n\u003cli\u003eTested to over 50psi of boost\u003c\/li\u003e\n\u003cli\u003eIncludes stainless steel hardware for installation\u003c\/li\u003e\n\u003cli\u003eNitrous nozzle bosses on outboard and valley side of each runner (16 total)\u003c\/li\u003e\n\u003cli\u003eProvisions to run 3 injector body lengths\u003c\/li\u003e\n\u003cli\u003eIncludes molded port, plenum and throttle seals\u003c\/li\u003e\n\u003cli\u003eIntake can be reversed on the engine\u003c\/li\u003e\n\u003cli\u003eBlack Cerakoted billet throttle flange\u003c\/li\u003e\n\u003cli\u003eOptional medium or short velocity stacks (sold separately)\u003c\/li\u003e\n\u003cli\u003eOptional PD ultralight billet -8 fuel rails\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eCathdral port applications:\u003cbr\u003eLS1\u003cbr\u003eLS2\u003cbr\u003eLS6\u003cbr\u003eLR4\u003cbr\u003eLM7\u003cbr\u003eL59\u003cbr\u003eLM4\u003cbr\u003eLM7\u003cbr\u003eL33\u003cbr\u003eLQ4\u003cbr\u003eLQ9\u003c\/p\u003e","brand":"Performance Design","offers":[{"title":"No; Intake Only","offer_id":48409050218694,"sku":"70606.00.BK-1","price":1399.99,"currency_code":"USD","in_stock":true},{"title":"Yes; Include Black Fuel Rails","offer_id":48409050251462,"sku":"70606.00.BK+70463.00.BK","price":1619.99,"currency_code":"USD","in_stock":true},{"title":"Yes; Include Polished Fuel Rails","offer_id":48409051955398,"sku":"70606.00.BK+70463.00PL","price":1619.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2716\/4086\/files\/performance-design-performance-design-carbon-ptr-intake-manifold-cathedral-port-1264275875.jpg?v=1792822208","url":"https:\/\/www.glennsautoperformance.com\/products\/performance-design-carbon-ptr-intake-manifold-cathedral-port","provider":"Glenn's Auto Performance","version":"1.0","type":"link"}
