What RPM range is this intake designed for?
This intake is designed to operate from 1,500-9,000 RPM, making it suited for higher-RPM performance use.

What kind of performance gains can I expect?
This intake is designed to improve airflow efficiency, throttle response, and power delivery compared to more restrictive stock-style setups.

Is this intake better for street or race use?
This intake is best suited for performance builds where airflow and power potential are priorities.

What type of intake manifold is this?
This is a low-rise design, for cathedral applications intake manifold built to improve airflow and support performance LS combinations.

Will this intake clear a stock hood?
It features a performance-oriented intake profile, so hood clearance should always be checked against your specific vehicle combination.

What material is this intake made from?
It is made from carbon fiber, which helps reduce weight while supporting strength and heat control for performance use.

What throttle body size or flange does this intake support?
This intake is designed around a 102.200 mm throttle body configuration, which supports increased airflow for EFI performance applications.

Does this intake have a removable top?
Yes, this intake uses a removable top design, which can make serviceability and configuration changes easier on performance builds.

Will this intake improve throttle response on my LS build?
Yes, this intake is designed to improve airflow and mixture distribution, which can help deliver stronger throttle response and more consistent power.

Is this a good upgrade from a stock intake?
Yes, this intake is a strong upgrade for compatible LS applications that need better airflow, stronger power potential, and improved performance over a stock-style manifold.

Does the black finish affect performance?
No, the black finish does not change the manifold's performance characteristics—it mainly changes appearance and gives the intake a more aggressive look.

Is the black finish durable for long-term use?
Yes, the black finish is designed for durability and corrosion resistance when properly maintained.
