Who Is This EVIL ENERGY LS Engine Intake Manifold For?

The EVIL ENERGY intake manifold is designed for performance-focused builders who need a high-rise EFI intake manifold for rectangular-port GM LS combinations. This LS engine intake manifold is best suited for users building LS3, L92, L99, or L76 engine combinations and looking for a polished LS aluminum intake with 102 mm throttle body compatibility and included EFI fuel rails.

This LS3 intake manifold is a strong fit for:

LS engine builders upgrading from a stock composite intake to a high-rise aluminum setup
6.0 LS intake manifold shoppers building L76-based performance combinations
LS high ram intake buyers planning turbocharged, supercharged, or high-RPM naturally aspirated EFI builds
LS swap enthusiasts who need a rectangular-port fuel injection manifold
Track-day, drag racing, and street/strip builders prioritizing upper-RPM airflow over stock-style packaging

Best Use Scenarios

This LS intake manifold is ideal for the following applications:

High-RPM EFI performance builds targeting strong top-end horsepower
LS3 intake manifold upgrades for rectangular-port 6.2L combinations
LS 6.0 intake manifold upgrades for L76 6.0L builds using EFI
Turbo and supercharged projects requiring a durable LS aluminum intake
Custom LS swap builds where hood clearance, throttle body size, and EFI layout are already part of the build plan
Race-oriented or weekend performance vehicles using a LS high-rise intake rather than a stock-height manifold

Important Buyer Fit Note

Because this LS high ram intake uses a HI-RAM (High-Rise) design and measures 12.03 inches in height, it is best for buyers who have already planned for additional hood clearance. It is not the ideal choice for stock hood applications or buyers seeking a low-profile street replacement manifold.

FAQS

Q: What engines is this EVIL ENERGY LS engine intake manifold designed for?
A: This EVIL ENERGY intake manifold is designed for GM LS applications using LS3/L92/L99/L76-style rectangular port cylinder heads. It is a performance-focused LS intake manifold for compatible 6.0L and 6.2L EFI engine combinations.

Q: Is this an LS3 intake manifold or a 6.0 LS intake manifold?
A: It can serve both applications when the engine uses the correct rectangular port setup. This makes it suitable for buyers searching for an LS3 intake manifold, 6.0 LS intake manifold, or LS 6.0 intake manifold for compatible LS builds.

Q: Is this intake manifold for EFI or carburetor setups?
A: This is an EFI intake manifold only. It is designed as a fuel injection manifold for electronic fuel injection systems and is not intended for carbureted applications.

Q: What makes this LS high ram intake different from a stock LS intake manifold?
A: This LS high ram intake uses a HI-RAM high-rise design with a large plenum and a 102 mm throttle body bore to support stronger airflow at higher RPM. Compared with many stock-style LS intake manifolds, it is better suited for performance-oriented EFI combinations.

Q: Will this LS high rise intake fit under a factory hood?
A: Because this LS high rise intake measures 12.03 in tall, hood clearance should always be checked before purchase. High-rise LS intake designs are commonly used on builds that already have additional hood clearance or modified engine bay packaging.

Q: Does this LS aluminum intake include fuel rails?
A: Yes. This LS aluminum intake includes EFI fuel rails, which helps simplify installation for customers building a complete EFI intake upgrade.

Q: Does this LS intake manifold support a 102 mm throttle body?
A: Yes. This LS intake manifold features a 102 mm throttle body bore, making it a strong match for high-flow EFI combinations that require increased airflow capacity.

Q: Is this LS manifold better for street driving or high-RPM performance builds?
A: Based on its HI-RAM design and listed RPM range, this LS manifold is best suited for upper-RPM performance applications. It is a popular style for race-oriented, boosted, or aggressive naturally aspirated EFI builds.

Q: Will my existing injectors, throttle body, and other EFI parts work with this intake manifold fuel injection setup?
A: Compatibility can vary by build. Before ordering, buyers should confirm throttle body size, injector setup, fuel rail layout, and other EFI hardware to ensure the intake manifold fuel injection system matches their specific LS combination.

Q: What should I verify before ordering this EVIL ENERGY intake manifold?
A: Before purchasing, confirm cylinder head port style, EFI compatibility, throttle body size, hood clearance, and your overall engine combination. Checking these details in advance helps ensure the EVIL ENERGY intake manifold is the right fit for your project.
