Increase throttle response and decreases turbo lag with the Yahua Charge Pipe Upgrade for your F or G Series BMW with a B58 engine. Please refer to the chart below for exact fitment. Every Yahua Charge Pipe is constructed from mandrel bent, T6061 grade aluminum including the flanges. Each flange is precision machined from CNC billet aluminum, including the throttle body, intercooler and vacuum connections. After these are welded, they¡¯re test fitted on multiple jigs in order to ensure proper fitment and a reliable, leak free connection.

Each Yahua charge pipe is finished in a durable wrinkle black powder coated finish that blends in perfectly with the engine bay. We also include one plugged 1/8¡å NPT bung that can be used for water injection, boost leak testing or as a boost source. The OEM charge pipe is prone to failure at both stock and tuned boost levels which is why we include everything necessary to replace your flimsy OEM chargepipe including high quality, 4-ply silicone couplers as well as stainless steel t-bolt clamps.

Additionally, we offer and recommend replacement throttle body c-clips and o-rings in case your original clip and gasket are lost or worn.
