These intake manifolds will work with OE or aftermarket cylinder heads. The Ultra 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.\n\nThe 300-621 Ultra Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines.\n\nThe 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\/div\u003e\u003ch3\u003eFeatures:\u003c\/h3\u003e\u003cul class=\"productpage_list\"\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.\u003c\/li\u003e\n\u003cli\u003eWith forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to be coupled to the supercharger or turbocharger being used\u003c\/li\u003e\n\u003cli\u003eModular design allowing the use of front-feed plenum entry\u003c\/li\u003e\n\u003cli\u003eIntake design facilitates custom inlet duct and throttle body placement \u003c\/li\u003e\n\u003cli\u003eLow height to fit under a stock or mildly modified hood.\u003c\/li\u003e\n\u003cli\u003eFront entry plenum flange allows design \u0026amp; fabrication of special throttle body adapters or inlet ducts for custom installations\u003c\/li\u003e\n\u003cli\u003eClears 4th Gen Camaro and C5 Corvette cowls and hoods without modification \u003c\/li\u003e\n\u003cli\u003eHigh volume fuel rails and mounting hardware included with _Ó-16 o-ring ports (8 AN)\u003c\/li\u003e\n\u003c\/ul\u003e\n\t\t\u003cdiv class=\"brandbox\"\u003e\n\t\t\t\u003cdiv class=\"brand-content\"\u003e\n\t\t\t\t\u003cp class=\"brand-title\"\u003eAbout Holley EFI\u003c\/p\u003e\n\t\t\t\t\u003cdiv class=\"brand-main\"\u003e\n\t\t\t\t\t\u003cdiv class=\"brand-image-container\"\u003e\u003cimg class=\"brand-image\" width=\"387\" src=\"\/\/images.holley.com\/387x\/brands_holley_efi_new_standard_fuel_background.jpg\"\u003e\u003c\/div\u003e\n\t\t\t\t\t\u003cp class=\"brand-text\"\u003eFind standalone EFI for LS, Coyote, Hemi and more at Holley.com.
