BMW N55 Turbocharger Outlet Seal Ring for Electronic Wastegate Engines

Keep your F Series six-cylinder running tight and leak free with this genuine BMW turbo outlet sealing ring. Perfect whenever you remove the front pipe, fit a catless pipe, install a high flow sports catalyst, or refit the factory catalyst, this OE part restores an air tight joint between the turbocharger and the front pipe to protect spool, torque and response.

Built for the heat and pressure of tuned N55 applications, this factory original gasket is the smart choice for maintenance and upgrades. We use this exact seal in-house on customer builds and our own cars and it seals first time. Owners consistently report a precise fit and zero fuss whether pairing with a performance front pipe or the standard converter.

Why this OE BMW turbo outlet gasket is the right choice

• Factory original BMW part for perfect alignment and a gas tight seal
• Stops exhaust leaks at the turbo outlet to maintain boost and reduce soot and fumes
• Ideal for performance upgrades including catless front pipes and sports catalysts
• Heat and pressure resistant for daily driving, spirited use and track days
• Direct replacement for worn or crushed seals during service or modification
