Q&A
What engines is this intake manifold compatible with?
This intake manifold is designed for GM LS Gen IV rectangle port applications, including 6.2L/376ci.
Will this intake fit LS rectangle port engines like a 6.2L LS application?
Yes, this intake is designed for LS rectangle port combinations, making it a strong fit for common Gen IV performance applications.
What fuel system is this intake designed for?
This intake is designed for EFI applications using multi-port fuel injection, making it a strong choice for performance LS builds.
What RPM range is this intake designed for?
This intake is designed to operate from 2,500-7,000 RPM, making it suited for higher-RPM performance use.
How does a single-plane intake help performance?
A single-plane intake is designed to support stronger high-RPM airflow, making it a good choice for aggressive performance combinations that want more top-end power.
Is this intake better for street or race use?
This intake is better suited for aggressive street, street/strip, and higher-RPM performance applications.
What type of intake manifold is this?
This is a single plane, for rectangle 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, with a front height of 5.417 in., center height of 5.417 in., rear height of 5.417 in., so hood clearance should always be checked against your specific vehicle combination.
What material is this intake made from?
It is made from aluminum, which helps reduce weight while supporting strength and heat control for performance use.
Does this intake support EFI-specific hardware?
Yes, this intake is designed around EFI applications and the supporting hardware needed for electronic fuel injection setups.
What else should I know before installation?
As with any performance intake upgrade, proper fuel, ignition, and tuning support are important to get the best results from the manifold.
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.
Emissions Notice
This Top Street Performance (TSP) product is designed for racing and off-road competition use only. It is not legal for use on public roads or emissions-controlled vehicles and does not comply with federal, state, or local emissions regulations. The buyer assumes all responsibility for legal use and installation.
What is a Emissions-Controlled Vehicle?
"An emissions-controlled vehicle is any vehicle equipped with a factory-installed emissions control system designed to reduce air pollution. These systems include catalytic converters, oxygen sensors, EGR (Exhaust Gas Recirculation) valves, and diesel particulate filters (DPF). Most vehicles manufactured after 1975 are considered emissions-controlled and must comply with federal and state emissions laws when used on public roads."
