Holley EFI intake manifolds feature port-matched upper and lower runners for reduced restrictions. Plus, the EGR passages have been relocated to the outside of the manifold to allow for the use of larger intake ports. The result is greater air capacity, which makes these manifolds the perfect choice for supercharged engines. They're available in a variety of styles and options; select the model designed for your vehicle and/or engine application.

Trick Flow® R-Series A460 Tunnel Ram Intake Manifolds were developed for all 8,000 plus rpm applications such as drag racing and tractor pulling. They feature a 2-piece design with interchangeable top covers so you can mount either single or dual Dominator-style carbs. They're made from thick-wall A319 aluminum for durability and the lower manifold feature bosses for nitrous and fuel injection nozzles. The lower manifold and top covers are sold separately; both pieces are required to make a complete manifold assembly. R-Series A460 manifolds can only be used with Trick Flow® PowerPort® A460 series cylinder heads.

The new line of Edelbrock VRS-4150 Race and Performance carburetors are packed with features that will appeal to racers, engine builders and carb tuners, as well as the hot street enthusiast looking to improve performance. The VRS-4150 carburetors are street friendly but race ready—and the one-piece, cast aluminum bodies fit all 4150 and 4500 carb flange manifolds—without requiring an adapter plate. With the new VRS Series carburetors many attributes, they make for easy tuning and great versatility in many applications. They are available in 650, 750, 850, and 950 cfm models, select the model suited to your application needs. Features, specs, and benefits: * A street throttle arm, PTFE-coated throttle shafts and built-in provisions for a standard GM three-wire TPS mount add features to the carburetor that are ideal for any user * Multiple vacuum hook-ups keep this carburetor usable on the street but still ready for the track with larger capacity fuel bowls and four circuit billet metering blocks with screw-in emulsion bleeds * The 20 percent larger capacity fuel bowls feature internal ribs to control fuel slosh, and a sculpted baffle directs incoming fuel to the sides to minimize bubbles * The floats have corner cuts to avoid shutting off the fuel flow during hard cornering, and jet extender notches and jet extenders in the rear to keep the jets covered in fuel under hard acceleration * Users are able to externally adjust idle bypass air as the adjustment screws are accessible without removing the air cleaner/scoop * The advanced idle circuit features interchangeable idle discharge jets in all four corners to allow for a smooth, clean idle with the use of big, low-vacuum camshafts * Normally found only in high end racing carbs, the VRS includes fully adjustable intermediate fuel circuits, which help to provide incredible throttle response * For greater control at high rpm, the high speed/main fuel circuit is split into two bleed circuits—one each for the lower and upper sections * As an additional feature, the power valves are located on both primaries and secondary's that support optimized jetting—the power valve will add fuel as necessary while the power valve protection circuit prevents diaphragm damage from backfires

Holley LS Modular Lo-Ram EFI intake manifolds are designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) 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 and a 105 mm throttle 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 modular design allows the use of front-feed plenum entry, while intake design facilitates custom inlet duct and throttle body placement. Additional features and specs: * Cast aluminum construction with satin silver finish * Modular design allows the use of front-feed plenum entry * Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification * With 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 * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits include 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
