BLOX Racing Honda Civic 1.5T 58mm DBW Throttle Body

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 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
