EVIL ENERGY LS1 LS2 LS6 EFI Intake Manifold with Fuel Rails

EVIL ENERGY LS EFI Intake Manifold with Fuel Rails

The EVIL ENERGY LS EFI intake manifold is designed for compatible GM LS1, LS2, and LS6 cathedral port engines that need an EFI-ready intake upgrade with included fuel rails. This LS intake manifold uses a cast aluminum performance layout for cathedral port LS combinations and is suitable for performance street cars, LS swaps, muscle car builds, drift cars, and track-day projects when the full engine setup supports the intake configuration.

For builders upgrading an LS engine intake manifold, the included fuel rails help simplify the EFI intake setup, but final compatibility still depends on injector style, fuel line fittings, regulator setup, throttle body size, MAP/IAT sensor needs, hood clearance, and tuning. This manifold is intended for LS1/LS2/LS6 style cathedral port cylinder heads, not LS3/L92/L99/L76 rectangular port heads.

Important: Always confirm cylinder head port shape, throttle body compatibility, injector length, fuel rail fittings, hood clearance, sensor placement, vacuum ports, gasket style, and tuning requirements before ordering.

Vehicle and Engine Fitment

This EVIL ENERGY LS intake manifold is designed for GM LS Gen III or Gen IV engines equipped with LS1, LS2, or LS6 style cathedral port cylinder heads. Common reference applications include Chevrolet Corvette C5, Chevrolet Camaro, Pontiac Firebird / Trans Am, Cadillac CTS-V, Holden Monaro, Holden Commodore, Holden HSV, Pontiac GTO, Chevrolet SSR, and compatible LS-swapped platforms.

Vehicle names are provided as reference examples only. Engine swaps, cylinder head changes, throttle body selection, injector length, fuel rail fittings, hood clearance, accessory routing, sensor placement, and tuning can affect final fitment. Always verify that your engine uses cathedral port LS cylinder heads before installation.

Package Contents and Installation Checklist

Before Installation, Check These Items

• Confirm that your engine uses LS1/LS2/LS6 style cathedral port cylinder heads.
• Do not use this manifold on LS3/L92/L99/L76 rectangular port heads unless your engine has compatible cathedral port heads installed.
• Confirm throttle body size, bolt pattern, cable or drive-by-wire setup, and throttle linkage requirements.
• Check injector length, injector O-ring style, fuel rail fittings, fuel pressure regulator setup, and fuel line routing.
• Check MAP sensor, IAT sensor, vacuum ports, PCV routing, brake booster vacuum, and any required adapters.
• Check hood clearance, accessory bracket clearance, firewall clearance, and air intake tube routing.
• Use suitable intake gaskets and follow the proper torque sequence during installation.
• EFI intake manifold changes may require tuning or calibration adjustments depending on the vehicle and build.

Why Choose This LS EFI Intake Manifold?

For many LS performance builds, airflow, injector compatibility, fuel rail setup, throttle body selection, sensor placement, and tuning support all matter when choosing the right manifold.

For Corvette, Camaro, Firebird, GTO, CTS-V, Holden, Chevrolet SSR, or LS-swapped projects using compatible LS1/LS2/LS6 cathedral port heads, this EVIL ENERGY LS engine intake manifold provides a practical upgrade path for performance street use, drift builds, track-day vehicles, and EFI LS projects. Final results depend on the full engine combination, throttle body, injectors, fuel system, camshaft, exhaust, tuning, and installation quality.

FAQ

Q: What engines does this LS EFI intake manifold fit?
A: This intake manifold is designed for compatible GM LS Gen III or Gen IV engines equipped with LS1, LS2, or LS6 style cathedral port cylinder heads. Always confirm your cylinder head port shape before ordering.

Q: Will this fit LS3 heads?
A: No. LS3/L92/L99/L76 style engines commonly use rectangular port heads, while this manifold is intended for LS1/LS2/LS6 style cathedral port heads.

Q: Are fuel rails included?
A: Yes. This LS EFI intake manifold includes fuel rails. Confirm injector length, O-ring size, fitting size, fuel pressure regulator setup, and fuel line routing before installation.

Q: Is this a carburetor intake manifold?
A: No. This is an EFI intake manifold for fuel-injected LS applications.

Q: What should I check before buying?
A: Check cylinder head port shape, throttle body size, injector compatibility, fuel rail fittings, MAP/IAT sensor needs, vacuum ports, hood clearance, gasket style, and tuning requirements before ordering.

Q: Does this intake manifold require tuning?
A: EFI intake manifold changes may require tuning or calibration adjustments depending on the vehicle, throttle body, injectors, airflow changes, camshaft, and ECU setup.
