Description

Designed specifically for LS engine swaps in classic vehicles, this high-flow intake system delivers improved throttle response and increased horsepower by drawing in cooler, oxygen-rich air through a less restrictive path. The 4" oversized reusable air filter—with 99% filtration efficiency—can be positioned on the driver or passenger side to fit tight engine bays and cleared radiator/pulley spacing. A powder-coated steel heat shield protects from debris and engine heat, while the smooth-walled aluminum tube optimizes airflow for a deeper engine sound under acceleration. Compatible with speed density systems or adaptable for round MAF sensors (additional couplers/clamps required), this washable filter only needs cleaning every 5,000 miles for lasting performance.

Airflow Routing to the Engine

Understanding an Air Intake System

An air intake system guides air from the filter to the engine. Compared to many factory setups, some aftermarket intake kits use smoother tubing and alternative filter designs to support more consistent airflow.

By refining how air is routed, an intake system can influence how evenly air reaches the engine under different driving conditions.

What Drivers May Observe

More consistent throttle behavior during everyday driving

Smoother engine response during acceleration

Noticeable changes in intake sound under throttle

A different overall driving feel compared to the factory intake

Compared to an air cleaner kit, a full air intake kit replaces more of the intake tract, offering a more noticeable change in airflow and driving feel.

Factory Intake vs. Aftermarket Intake Kit

Factory Intake

Designed with noise control, packaging, and emissions requirements in mind
Prioritizes broad compatibility and long-term durability

Performance Intake Kit

Designed to reduce airflow restriction in the intake path
Uses smoother intake routing and alternative filter media
Built for specific vehicle applications

When an Intake Kit Is Typically Considered

Are replacing or updating factory intake components

Care about airflow consistency and intake system design

Prefer bolt-on components tailored to their vehicle

Want to change intake sound characteristics

Frequently Asked Questions

What is an Air Intake Kit? +

An air intake kit is a performance upgrade that replaces your factory air intake system with components designed to increase airflow to your engine. It typically includes a high-flow air filter, smoother intake tubing, and sometimes a heat shield or air box.

What are the benefits of installing an air intake kit? +

Air intake kits improve engine breathing for better throttle response, increased horsepower and torque, enhanced engine sound, and potentially improved fuel efficiency. They also provide easier filter access for maintenance.

Will an air intake kit increase horsepower? +

Yes, most kits provide measurable gains ranging from 5-25 horsepower depending on your vehicle and configuration. The improvement comes from reduced intake restriction and cooler, denser air reaching your engine.

Will it change my engine's sound? +

Yes, you'll notice increased intake noise during acceleration. On naturally aspirated engines, you'll hear a deeper growl. On turbocharged vehicles, the turbo spool and blow-off sounds become much more pronounced and exciting.

Do I need tuning after installing an air intake? +

Most modern air intake kits are designed to work with your factory tune. However, for maximum performance gains and optimal air-fuel ratios, especially on newer vehicles with sophisticated ECUs, a custom tune is recommended.

Are air intake kits street legal? +

Many quality air intake kits are CARB-exempt and 50-state street legal when they carry an Executive Order (EO) number. Always check the product's CARB certification status for compliance with your state's emissions regulations.

Can I install an air intake kit myself? +

Yes, most kits are designed for straightforward DIY installation with basic hand tools. Installation typically takes 30-90 minutes and involves removing the factory air box and components, then installing the new system with provided hardware.

What's the difference between cold air intakes and short ram intakes? +

Cold air intakes (CAI) position the filter outside the engine bay to draw cooler, denser air for maximum power. Short ram intakes (SRI) are shorter, placing the filter in the engine bay for easier installation and increased sound, though with potentially warmer intake air.

How often should I clean the air filter? +

Reusable performance filters should be cleaned every 25,000-50,000 miles under normal conditions, or more frequently if driving in dusty environments. Always use the manufacturer's recommended cleaning kit for proper maintenance and oiling if required.
