Holley/MSD Introduce
Our New & Hot LS Products

Holley Mid-Mount Complete Accessory Systems pull all the accessories for your GM LS engine in tighter than ordinary accessory drives for a clean, compact look. At the heart of it is the revolutionary “bracketless” design (patent pending), where all accessories attach directly off the water pump for an integrated look that shows off your horsepower – not your accessories.

GM’s new Gen V LT direct injected engines are starting to find their way into a large variety of vehicles. They make great power, plus they’re very durable and reliable. Unfortunately, the factory oil pans don’t always fit or they hang too low for today’s hot rods. Holley’s new LT Swap Engine Oil Pan is designed to help! It provides maximum clearance to the chassis and ground, plus provides an OE (Original Equipment) style fitment for durability and proper sealing.

Available with single or dual injector provisions and a burst panel flange, the LS3 Ultra Lo-Ram intake manifold is designed for boosted combinations with hood clearance in mind. The Holley LS3 Ultra Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS3/L92 cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application.
