Description
Aeroflow GM LSA Thermo Plastic 10mm Supercharger Hat Spacer Kit
Engineered to optimise airflow distribution and reduce thermal transfer on GM LSA supercharged engines.
Overview
The Aeroflow Performance AF1850-1008 thermoplastic supercharger spacer kit is developed specifically for the GM LSA supercharged engine. Sitting underneath the supercharger hat, this precision spacer raises the assembly by 10mm to relieve restriction and deliver significantly better airflow to the rear cylinder banks. Manufactured from high-grade thermoplastic, it insulates the supercharger from engine heat soak, helping lower intake temperatures and maintain peak horsepower under heavy load.
Key Features
- ☑ High-grade thermoplastic construction acts as a thermal barrier to reduce heat soak
- ☑ 10mm spacer height increases plenum volume and airflow to rear cylinders
- ☑ Integrated O-ring seal eliminates the need for liquid silicone or RTV sealant
- ☑ Complete with replacement extended mounting bolts required for installation
- ☑ Direct-fit upgrade designed specifically for stock GM LSA supercharger hats
