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.

FMCT6 B58 Breather Catch Tank for Mk5 Supra A90 and BMW Z4 G29

Keep your B58 straight-six running clean and consistent with this premium crankcase vapour separator kit. The 400 cc catch tank traps oil mist, fuel vapour and moisture from the positive crankcase ventilation system before it can coat your intake pipes, turbo inlet and intercooler. Expect a cleaner intake path, reduced valve deposit build-up and steadier performance on spirited road drives and track days.

Designed specifically for the B58 platform, the assembly locates neatly behind the OE airbox heat shield for a factory-style, discreet finish. It is a proven reliability upgrade for stock cars and an essential add-on for remapped, hybrid-turbo or hard-driven builds. We run this setup on our own customer A90 and G29 projects and feedback has been outstanding for both fit and function.

Key benefits

  • Purpose-built for Toyota Mk5 A90 and BMW G29 with the B58 engine for a precise, model-specific fit
  • Captures blow-by contaminants to help minimise intake valve coking and sludge formation
  • Improves breathing efficiency on tuned cars and daily drivers alike
  • Direct bolt-on fitment with integrated bracket behind the factory airbox shield for an OEM look
  • 0.4 litre tank capacity with a dipstick for quick level checks and straightforward draining
  • Completely reversible installation with no cutting or permanent changes
  • CNC machined billet aluminium fittings with a subtle black anodised finish
  • Supported by Forge Motorsport’s limited lifetime warranty for peace of mind

Construction and spec

  • Developed using 3D CAD for exact B58 geometry and hose routing
  • Hoses feature a smooth, fuel-resistant nitrile inner and a reinforced stainless wire braid outer
  • Engineered to prevent hose expansion under pressure and collapse under vacuum for stable PCV function
  • Operating temperature range from -54°C to +150°C

Result: a cleaner induction system, less oil pooling in charge pipes, and consistent performance pull after pull. Ideal preventative maintenance for any A90 or G29, and a smart complement to intakes, intercoolers and software upgrades.

Vehicle fitment

  • Toyota GR Supra Mk5 A90 B58B30, 2019 onward
  • BMW Z4 G29 B58 models, 2018 onward
