  • Description

One area the L15B7 needed immediate improvement was the throttle body.  The OEM throttle body measures 56mm at the opening but tapers down to a narrow 50.5mm at the manifold.  This taper chokes incoming air and robs the engine of potential power.
BLOX Part# BXIM-0022-

BLOX Racing's newest throttle bodies are available in 56mm and 58mm bores sizes, with minimal tapering.  Each is CNC machined from billet aluminum and incorporates a new drive-by-wire motor. BLOX Racing has spent months road testing making sure there was not corruption between the drive-by-wire motor and ECU.

The larger throttle bodies offer increases in airflow resulting in additional horsepower and torque gains.  Throttle bodies include hardware and reuse the factory's O-ring gasket.

For Off-Road use only.
