FAQS

Q: What LS engine applications does this EVIL ENERGY intake manifold fit?
A: This EVIL ENERGY EFI intake manifold is designed for GM LS applications using LS3/L92/L99/L76-style rectangular port cylinder heads, including 6.0L L76 and 6.2L LS3/L92/L99 combinations.

Q: Is this intake manifold for rectangular-port or cathedral-port LS heads?
A: This manifold is built for rectangular-port LS cylinder heads. It is not a direct fit for cathedral-port combinations unless your build uses additional conversion parts.

Q: Will this 6.0 LS intake manifold work on my L76 engine?
A: Yes, the listed compatibility includes the GM 6.0L L76 platform, provided your engine uses the correct LS3/L92/L99/L76-style rectangular port head configuration.

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

Q: Is this LS HI-RAM intake better for street driving or high-RPM performance builds?
A: This HI-RAM high-rise design is best matched to high-output EFI builds that operate in the upper RPM range. Based on the listed powerband, it is more suitable for high-RPM naturally aspirated, turbo, or supercharged combinations than for stock-style low-RPM driving.

Q: Will this LS high-rise intake manifold fit under a stock hood?
A: Buyers frequently ask about hood clearance with HI-RAM intakes. With a listed height of 12.03 in (305.46 mm), you should carefully measure your engine bay and hood clearance before ordering, especially on Corvette, Camaro, and truck applications.

Q: Does this intake manifold accept a 92 mm throttle body?
A: Yes. This manifold features a 92 mm throttle body bore. As with many LS swaps, buyers should still confirm throttle body style, bolt pattern, and overall setup compatibility before installation.

Q: Are fuel rails included with this LS intake manifold?
A: Yes. The product information lists EFI fuel rails included, which is an important feature for buyers planning a complete EFI manifold upgrade.

Q: Are injectors, throttle body, and other EFI components included?
A: The provided product information confirms EFI fuel rails are included, but it does not list injectors or a throttle body. Customers should verify what additional EFI components are needed for their specific build.

Q: Will this manifold fit my Corvette, Camaro, Escalade, G8, or Holden exactly as listed?
A: The listed vehicles are compatible applications for the correct LS rectangular-port EFI engine combination, but actual vehicle fitment can still depend on hood clearance, accessory layout, throttle body choice, and the rest of your swap or build configuration.
