Product Details
The Big Air is the 8" version of our Stage 3 intake, built for maximum airflow on the LC4 platform. It's the intake used in both of our dyno-proven packages.
Install requirements
The Big Air intake is 8" long and requires ECU relocation, a battery tray modification and a smaller lithium battery. JB Performance does not sell batteries.
Heat management
These engines run hot. Pair the Big Air with our insulating tray to keep engine heat away from the intake.
Tuning
More air needs more fuel. Pair the intake with our custom PC6 map or an ECU reflash.
