Holley aluminum LS valve covers will give your Chevrolet LS Series engines a totally new look. Manufactured from cast aluminum, they come in four different finishes, and feature a billet aluminum oil fill cap. Some valve covers in this series eliminate the need for the factory ignition coil bracket. Instead, the coils bolt directly to the valve covers for a nice angled look! Holley aluminum LS valve covers reuse the factory gaskets and bolts, will work with .750 in. lift camshafts using stock-style rocker arms, and fit all ignition coils with 72mm spacing.

Holley Sniper offers OE-style 255 lph EFI fuel pump modules for a wide range of vehicles, including many Chevy, Pontiac, Buick, Oldsmobile, GMC, Ford, Mercury, Jeep, Dodge and Plymouth cars and trucks from the 1950s, '60s, '70s, and '80s. These in-tank modules are high-pressure units that flow 255 liters per hour (LPH) and are capable of supporting electronic fuel injection (EFI) engines producing up to 550 hp. A pre-calibrated fuel level sending unit designed to work with the factory fuel gauge for this application is included. Each module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates. Fuel pressure is internally regulated to 58 psi, eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator; no separate return line is required because these modules return excess fuel right inside the tank! The Holley Sniper EFI fuel pump module was designed as a direct replacement for your factory pick-up and sending unit. There's no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line—just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line.

Holley EFI Smart Coils are a bolt-in ignition upgrade for your Gen III HEMI or Coyote engine. Here's the difference over a stock coil: they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. The Smart Coils are available individually and in sets of 8. * For Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 and Coil Extension Harnesses 558-326 for a plug-and-play solution. Features: * Direct bolt-on to factory valve covers * Same wiring pinout as other IGN-1A coils for easy plug-in upgrades (Will not work with factory wiring) * More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence * Low current draw means less demand on the electrical and charging system * Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECUs * Maximum operating voltage of 18 V—for compatibility with both 12 V and 16 V electrical systems found in many performance/race applications
