Upgrade Your Engine's Airflow

If you're looking to boost your engine's performance, an upgraded intake system is a fantastic way to increase airflow while ensuring that debris and particles from the road are properly filtered out. This is especially true for vehicles equipped with the M177 LS2 and twin turbochargers. With higher airflow, your engine can generate more power, particularly noticeable in vehicles that are tuned or have upgraded turbochargers. The limitations of stock airboxes become evident, even with high-flow filters, especially when paired with upgraded turbos.

Why Choose the Weistec M177 LS2 Air Box?

The Weistec M177 LS2 Air Box is designed to provide superior airflow. It features twin cone filters that significantly outperform the OEM-sized panel air filters. These filters are enclosed within the airbox to keep heat from the engine bay at bay, ensuring that the air your engine breathes is cool and fresh. The airbox utilizes the same air inlets on the radiator core support as the stock airboxes, drawing in fresh air right from in front of the radiator.

Easy Maintenance and Customization

Maintenance is a breeze with the removable carbon fiber top panels, allowing easy access to the filters. For those who love the sound of turbo induction, you can leave the tops off with minimal impact on performance. The airbox also has provisions for bolting on bypass valves and is compatible with our M177 LS2 VTA Adapters for that iconic "blow off" noise.

High-Quality Filter Design

The filters feature a 4-ply lightly oiled cotton media filtration element, perfect for high airflow applications. This design minimizes airflow restriction while still providing excellent filtration to protect your engine during both road and track use. The airbox lids are crafted with a base layer of 0.03" thick 304 stainless steel and a top layer of carbon fiber, giving your intake a sleek and polished look.

Unmatched Fitment and Performance

Our core support adapters are made from 80 durometer silicone, attaching the airbox directly to the core support-mounted air intake ducts for unrestricted airflow. Unlike competitors that use stock intake core support adapters with a bellows design, which adds restriction, the Weistec M177 LS2 Air Box ensures optimal performance and isolation from engine bay heat.

Engineered for Maximum Efficiency

Each turbo in the twin-turbo system is fed by its own intake tube and conical filter, featuring a 3.5" diameter flange and a total filter element area of 175.5 square inches. This setup provides a massive 228% increase in airflow area compared to stock filters. Our intake tubes have a 3" OD (approximately 2.75" ID) outlet to each turbo, greatly reducing restriction compared to the stock intake tubes.

Performance You Can Trust

In summary, our intake system is designed for the least restrictive and highest airflow cold air performance on the market. With the largest filter surface area available in any aftermarket cold air intake system, we deliver a smart design that maximizes airflow to your turbos. Our claims are backed by dyno charts that we proudly showcase on our page.
