Gen II Billet LSA Lid

Gen II Billet LSA Lid – Maximize Power, Minimize Heat

Unlock serious performance gains with the Gen II Billet LSA Lid—the ultimate intercooler lid upgrade for LSA builds. Designed to fit Harrop 2650i and GM LSA superchargers, this lid boosts airflow, lowers intake temps, and delivers measurable horsepower gains. It’s the next evolution in cooling efficiency and high-boost reliability.

Improved Cooling and Airflow for More Power

Compared to stock LSA lids, this Gen II version increases both intercooler size and plenum volume. As a result, your supercharged engine breathes easier and stays cooler—even under wide-open throttle.

• Over 60% larger intercooler area
• Optimized air channels reduce turbulence
• Expanded plenum volume promotes better cylinder filling
• Improved charge air temps mean more aggressive tuning potential

Moreover, the lid’s design reduces heat soak—keeping intake temperatures consistently lower, even after repeated pulls or extended sessions on the track.

Perfect Fit for Harrop 2650i and GM LSA Systems

Engineered to match perfectly with Harrop’s 2650i and GM’s LSA blowers, the Gen II Lid bolts on with no modifications. It retains factory sensor ports and bypass valve locations, making installation quick and easy.

Compatible applications include:

• 2009–2015 Cadillac CTS-V
• 2012–2015 Camaro ZL1
• LSA-swapped LS engines in custom builds

Whether you're working on a clean street setup or a full-on race application, this lid delivers proven performance with OEM-like integration.

Key Features at a Glance

Here’s what makes the Gen II Billet LSA Lid a must-have:

• CNC-machined from high-strength billet aluminum
• Supports OE and aftermarket intercooler bricks
• Dual-ORB fittings for flexible coolant routing
• Anodized black finish for durability and corrosion resistance
• Designed, tested, and made in the USA

In testing, this lid dropped IATs by up to 30°F compared to the factory unit.

Easy Installation with Big Results

Because the Gen II lid uses stock mounting points, the installation process is simple. It includes proper clearance for sensors and comes pre-threaded for common fittings. Even better, it supports higher boost levels and increased blower speeds—giving your build room to grow.

Furthermore, this lid is ideal for setups targeting 1,000+ horsepower, especially when paired with ported heads, cam upgrades, and fuel system enhancements.
