M57 AIR INTAKE + PCV

DEFAB Stainless Snorkel Kit - Defender Puma

Australian-made 3.5-inch stainless raised-air-intake system designed to pair neatly with the DEFAB sealed airbox.

Key features

• CNC-bent 304 stainless steel, 3.5-inch diameter
• Classic ram-head intake
• Nylon lower transition for a smooth connection into the DEFAB airbox
• Compatible with cyclone-style intake heads for dusty conditions
• Blasted and powder-coated finish

Kit includes

• Snorkel with wing-top entry plate
• Nylon under-wing transition adapter
• Ram intake head
• Silicone joiner for connection to the DEFAB sealed airbox
• Mounting screws

Other engine applications

The kit can be adapted to 300Tdi and potentially TD5 applications, but custom plumbing is required and must be worked out by the installer.

Water crossings

Fitting a snorkel alone does not make a vehicle safe for deep-water crossings. The complete intake system, including the airbox, joins and fittings, must be sealed and leak-checked after installation.

M57 SWAP MAF ADAPTER to 3"

Adapts the BMW single turbo oval shaped MAF Sensor found on M57N and M57N2 - to 3"

THIS is the ONLY catch can we recommend for M57 Swapped Defenders, Patrols, Land Cruisers etc

We see people ALL THE TIME fitting catch cans that are far to small for an M57, which leads to a host of issues and oil weeping/leaking!

This BOSSVENT Universal Kit has the following specifications:

• Power Rating: 200 – 450kWBlow-by
• Flow Rate up to 400 lt/min
  

BossVent Catch cans prevent contaminants from entering the air intake manifold, potentially eliminating the need to block off your EGR valve due to the absence of oily residue in the system.

This BossVent Kit includes:

• 1x BossVent XL (Fitted with 2 x high efficiency filters)
• 1x Universal In-Cabin Switch
• 1x OEM style in-cabin alert Switch
• 1x 16mm (5/8″) oil resistant hose x 4m long
• 2x 16mm (5/8″) straight joiners
• 2x 16mm (5/8″) 90 elbows
• 2x 16mm (5/8″) – 25mm (1″) oil resistant reducer
• 1x Wiring Harness Kit (Medium length) 3.2m long
• 1x Fastener Kit (Universal)
• 1x Universal Drain Kit

PLEASE NOTE: THIS IS A UNVERSAL FITMENT KIT AND YOU WILL NEED TO USE YOUR NOGGIN IN REGARDS TO PLACMENT, FITTING, AND PLUMBING UP

Important: water-ingress protection

Fitting a sealed airbox does not automatically make a vehicle safe for water crossings. Proper installation is essential. Check that the complete airbox and snorkel system is actually sealed after fitting.

DEFAB Engineering / KINGPIN Fab hold no responsibility for engine water ingress after fitting this product.
