The ARM B58 Charge Pipe is a bulletproof charge pipe replacement for the plastic OEM B58 charge pipe. The ARM B58 Charge Pipe increases the diameter over the OEM charge pipe, resulting in increased airflow from the turbo to the engine, and improved throttle response. Upgrading the charge pipe on your B58 is one of the basic steps in ensuring your B58 is protected against a charge pipe failure. In addition to making sure you have a reliable means of transporting the charge air from the turbo to the throttle body, the ARM B58 Charge Pipe comes with Tri-Port capability giving you 3 options for tapping into the charge pipe for meth, boost, or nitrous.
CONSTRUCTION
The ARM B58 Charge Pipe starts at the turbo with a CNC machined fitting which seals tightly at the turbocharger outlet port. It then transitions to the mandrel bent 2.5″ piping for smooth transitions and to match the turbo outlet.
The 6 layer reinforced silicone coupler connects the 2.5″ piping to the larger 3″ upper charge pipe section. This runs all the way to the CNC 3-bolt throttle body flange. The silicone coupler is secured using our constant tension T-bolt clamps to ensure that the connection doesn’t loosen over time. The upper charge pipe incorporates machined connections for the temperature and MAP sensors to ensure a precise fit.
The ARM B58 Charge Pipe incorporates Tri-Port 1/8″ NPT bungs. These 3 bungs are useful for running a heavy dose of methanol injection, tapping in for secondary boost gauge, nitrous injection, or anything else your heart desires! More ports means more options, and with the ARM charge pipe you have 3.
