Its 300-130 style cast aluminum body routes air through two plenum planes to balance low-end response with upper rpm pull. It suits engine builders and enthusiasts assembling a cathedral port LS for street performance use.\u003c\/p\u003e\u003ch4\u003eOverview\u003c\/h4\u003e\u003cp\u003eThis dual plane mid-rise intake manifold for GM is a cast aluminum replacement designed for cathedral port LS-series engines such as LS1, LS2, and LS6. The dual plane design splits the intake charge between two plenums to strengthen low and mid-range torque while keeping top-end airflow usable. It is made for engine builders and enthusiasts who want a durable manifold for a street-driven or mild performance LS build.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual plane runner design balances low-end torque with mid-range and upper rpm power\u003c\/li\u003e\n\u003cli\u003eMid-rise profile offers a compromise between low-profile and tall single plane manifolds\u003c\/li\u003e\n\u003cli\u003eCathedral port bolt pattern and port shape match GM LS1, LS2, and LS6 cylinder heads\u003c\/li\u003e\n\u003cli\u003eCast aluminum construction provides strength and heat resistance for demanding engine bays\u003c\/li\u003e\n\u003cli\u003e300-130 style reference number for easy cross-checking against existing part listings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor GM LS1 cathedral port engines\u003c\/li\u003e\n\u003cli\u003efor GM LS2 cathedral port engines\u003c\/li\u003e\n\u003cli\u003efor GM LS6 cathedral port engines\u003c\/li\u003e\n\u003cli\u003efor GM cathedral port cylinder head builds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStreet performance engines seeking strong part-throttle and mid-range response\u003c\/li\u003e\n\u003cli\u003ePump-gas LS builds where low-end torque matters more than peak horsepower\u003c\/li\u003e\n\u003cli\u003eEngine swaps and rebuilds using cathedral port LS heads\u003c\/li\u003e\n\u003cli\u003eWeekend track and drag builds needing a broad, usable powerband\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e300-130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConfiguration\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDual plane, mid-rise\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePort Style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCathedral Port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Engines\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGM LS1, LS2, LS6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCast aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Will this manifold work with stock LS1 cathedral port heads? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, it is designed for cathedral port LS1, LS2, and LS6 style heads, though you should confirm port alignment and throttle body compatibility before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Do I need tuning after installing this intake manifold? \u003cstrong\u003eA:\u003c\/strong\u003e Most builds benefit from a tune, since airflow changes can shift fuel trims and idle quality on cathedral port LS engines.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSlight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.\u003c\/em\u003e\u003c\/p\u003e","brand":"Solid Spare","offers":[{"title":"Default Title","offer_id":50554643972182,"sku":"ZZ3N00835","price":296.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/8460\/0662\/files\/s-l1600_9dae393e-1291-4d8e-8802-99bd4297f5a7.jpg?v=1790897747","url":"https:\/\/www.solidspare.com\/products\/dual-plane-mid-rise-intake-manifold-for-gm-ls1-ls2-ls6-cathedral-port-300-130","provider":"Solid Spare","version":"1.0","type":"link"}
