Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

BMW 3 Series E90 E91 E92 E93 335i 335d Charge Air Seal Ring | Part No. 11617791470

Eliminate pressure loss and bring back crisp throttle response with this original equipment seal ring for the charge air connection. Part number 11617791470 is the correct factory replacement sealing ring for the junction between the charge pipe and the turbocharger or intercooler on BMW 3 Series E9x 335i and 335d models. If you are chasing a hiss under load, oily residue at the pipe joint or wavering boost, this OE seal is a quick, low‑cost fix that restores tight, leak‑free performance.

This genuine BMW sealing ring delivers an exact fit and a reliable airtight join at the charge air coupler. It is ideal any time you refit intake pipework, swap a pressure pipe, or service the intercooler connection. We use this ring on our own builds and customer cars and it consistently stops boost creep and helps return smooth, repeatable power.

Key advantages

  • OE fitment for a precise, airtight seal at the charge air junction
  • Helps cure pressure leaks, hesitation and oil misting at the coupling
  • Perfect when installing a new pressure pipe, intake hose or intercooler
  • Factory quality and durability for daily driving and spirited use
