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.

BMW N54 External Breather Conversion Fitting by VTT - Billet 6061-T6, -8AN, O-rings - E60 E82 E89 E90 - 1M, 335i, 525i, Z4 35i

Take control of crankcase pressure on your N54 with this CNC machined aluminium block-off fitting from Vargas Turbocharger Technologies. Designed for enthusiasts moving to an external breather and catch tank set-up, this tidy manifold port blocker seals the factory passages at the intake side and gives you a robust -8AN male connection for straightforward hose routing to a catch can. It is clean, leak resistant and proven on both tuned and standard engines.

  • Aircraft grade 6061-T6 billet alloy for strength and long service life
  • Precision O-ring sealing for a tight, boost safe fit
  • -8AN male outlet for AN-8 hose to your oil catch tank or custom breather layout
  • Blocks the intake runner galleries so you do not need to plug the head ports individually
  • Ideal foundation for external crankcase venting and catch can plumbing

Why N54 owners choose this fitting

Reduced blow-by into the intake, better oil control and a cleaner engine bay. This billet block-off plate and breather adaptor is a simple, high value upgrade for reliable crankcase management on daily drivers, track builds and high boost applications. We have fitted these in-house at MJ Modifications and customer feedback has been excellent for machining quality, fitment and durability.

Compatibility

Suits BMW N54 engines across the E60, E82, E89 and E90 platforms including 1M, 335i, 525i and Z4 35i. If you would like us to confirm suitability, we can check against your registration or last 7 of VIN before dispatch.

What you receive

  • VTT billet N54 manifold PCV block-off fitting
  • Both required O-rings

High boost note

For vehicles running around 25 psi or more, we recommend also using a head port block kit to prevent valve cover gasket pressurisation. Pair this fitting with a suitable catch can for the best results.

Professional installation recommended. MJ Modifications offers fitting at our Warwickshire workshop with nationwide support. Request a quote at info@mjmodifications.co.uk.
