These intake manifolds will work with OE or aftermarket cylinder heads. Plenum top is machined for a standard large 6-1\/8 in. x 3-1\/8 in. burst panel. SFI approved burst panels, burst panel frame sets, and gaskets may be purchased from various manufacturers such as Allstar Performance or Specialty Fasteners\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eThe Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and the 105 mm throttle body part number 112-581 or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The 300-623 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. The fuel rail kits come with two sets of brackets. A set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors.\u003c\/p\u003e\n    \u003cp class=\"mt-2\"\u003eBurst Panel Flange\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003chr\u003e\n  \u003ch3\u003eFeatures\u003c\/h3\u003e\n  \u003cdiv\u003e\n    \u003cul\u003e\n      \u003cli\u003eDesigned for GM LS Gen III and IV engines equipped with GM LS1\/2\/6 (cathedral port) cylinder heads\u003c\/li\u003e\n      \u003cli\u003eDesigned for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application.
