The Modular Mid-Rise intake utilizes the popular Holley LS1\/LS2\/LS6 cathedral port Mid-Rise 2 x 4 intake manifold along with a purpose built plenum base adapter and a Holley 92MM EFI plenum top which converts it into a Mid-Rise EFI intake manifold. With a max overall height of only 10.44 in., the Mid-Rise manifold is an excellent choice for street and performance street\/strip applications with a powerband from 1,500-6,500 RPM and limited hood clearance. Its perfect for a blow-thru or turbocharged application. Being part of the Holley modular intake line means that this intake is not only available as a complete kit with intake, adapter, 92MM top and fuel rails, but all parts can also be purchased separately for a custom intake build. The plenum adapter (PN 300-267BK) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eProvides great performance to 6500 rpm for street\/strip performance applications while providing the look of a racing EFI intake manifold\u003c\/li\u003e\n\u003cli\u003eUnique modular design allows the combination of a traditional dual-plane layout with an EFI manifold plenum to produce great mid-range torque without compromising top end power\u003c\/li\u003e\n\u003cli\u003eGreat for supercharged or turbocharged engines\u003c\/li\u003e\n\u003cli\u003ePower band from 1500-6500 rpm\u003c\/li\u003e\n\u003cli\u003eMay require an aftermarket hood for some vehicle applications.\u003c\/li\u003e\n\u003cli\u003eCast aluminum construction\u003c\/li\u003e\n\u003cli\u003eIntended for use on all GM LS Gen III or IV engines equipped with LS1\/LS2\/LS6 style cathedral port cylinder heads (recalibration of the ECU may be required when using this intake manifold design with OE ECU).\u003c\/li\u003e\n\u003cli\u003eBlack Ceramic Coating for an aggresive look in your engine compartment\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: \u003cspan\u003eHolley\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: \u003cspan\u003eAir and Fuel Delivery\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eEmission Code\u003c\/strong\u003e: \u003cspan\u003e3\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eEngine\u003c\/strong\u003e: \u003cspan\u003eGM LS1\/LS2\/LS6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGrade Type\u003c\/strong\u003e: \u003cspan\u003ePerformance\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eManifold Color\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eManifold Material\u003c\/strong\u003e: \u003cspan\u003eAluminum\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eManifold Mount Hole Quantity\u003c\/strong\u003e: \u003cspan\u003e12\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003epart type\u003c\/strong\u003e: \u003cspan\u003eEngine Intake Manifold Conversion Kit\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: \u003cspan\u003eIntake Manifold\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSub Category\u003c\/strong\u003e: \u003cspan\u003eService Kits\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eType of Component\u003c\/strong\u003e: \u003cspan\u003eManifold Top\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eWarning\u003c\/strong\u003e: \u003cspan\u003eCalifornia Proposition 65\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: \u003cspan\u003eManufacturer's Limited 90 Day Warranty\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Holley","offers":[{"title":"Default Title","offer_id":49931466113302,"sku":"HOL-300-267BK","price":345.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_300-267bk_01_normalized.jpg?v=1776488974","url":"https:\/\/www.cspracing.com\/products\/holley-300-267bk-mid-rise-plenum-base-adapter-kit","provider":"Complete Street Performance","version":"1.0","type":"link"}
