Manufactured by \u003cstrong\u003eHolley EFI\u003c\/strong\u003e, this black single-injector version is built for Gen III\/IV LS engines using LS3\/L92-style rectangular-port cylinder heads and is designed around turbocharged and supercharged combinations operating in the 3500-8000 RPM range.\u003c\/p\u003e\n\n\u003cp\u003eThe Lo-Ram’s low overall height helps builders package a top-mounted air-to-water intercooler or fit the manifold under tighter hood lines, while the removable top and modular plenum design allow flexibility in how the induction system is configured. High-volume fuel rails, a 105mm throttle body opening, and -8AN-compatible rail ports make this a strong foundation for high-horsepower LS combinations.\u003c\/p\u003e\n\n\u003ch4\u003eIncludes:\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e(1) Holley Lo-Ram LS3\/L92 Intake Manifold Base\u003c\/li\u003e\n  \u003cli\u003eTop-Feed
