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\", 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.  It's 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 300-267) will accept all of the popular Holley Hi-Ram plenum tops as a foundation for custom induction systems.","brand":"Holley","offers":[{"title":"Default Title","offer_id":50228858552597,"sku":"BBVL_300-267","price":311.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0845\/6844\/1109\/files\/300-267_02.jpg?v=1791188004","url":"https:\/\/shop.davesusa.com\/products\/holley-mid-rise-plenum-base-adapter-kit-gm-ls1-ls2-ls6-300-267","provider":"Dave's Auto Center","version":"1.0","type":"link"}
