Iceman is FED’s flagship intercooled LS / LT manifold — a modular air-water intercooled system designed to push your charge temperatures down on naturally aspirated, nitrous, or remote-boost builds. CNC-machined entirely from billet aluminum, capable of supporting 2,000 HP applications, with a generous 102mm throttle body opening and your choice of single or dual injector runners on -10AN fuel rails.
Available in LS1/2/6 Cathedral, LS3, LS7, LT1, and LT4 port patterns. Cathedral-port heads only available with single injector configuration. Optional burst panel with adapter plate for race-only builds (may add to lead time). Manifold is for race applications — some firewall modification may be necessary to ensure proper fitment.



BUILT TO ORDER · 8–10 week lead time direct from FED. Manifold is for race applications — some firewall modification may be required for proper fitment. Optional burst panel may add to lead time. LS1/2/6 cathedral-port models only available in single-injector configuration. By placing this order you accept FED’s no-return / no-cancellation policy on built-to-order billet manifolds.
Frankenstein Engine Dynamics builds every billet manifold on the same CNC equipment they use for their NHRA Pro Stock and Pro Mod customers. No casting, no porting, no compromise.
You'll get an instant confirmation email with your part details and invoice. We source from a network of authorized suppliers across the country, so lead times vary by brand and part type — we'll send a tracking number the moment your parts move.
Made-to-order builds — carbon fiber bodywork, fabricated systems, custom finish work — run longer than off-the-shelf items because they're built per order. You'll get progress updates throughout the build.
