Key features
Australian made
Sealed airbox construction
Washable dry-flow air filter requiring no filter oil
Billet-machined MAF sensor holder built to original sizing
Duckbill drain valve

300Tdi applications
The airbox can be adapted to a 300Tdi, but custom intake plumbing is required and is the responsibility of the installer.
Water crossings
A sealed airbox does not automatically make the vehicle safe for deep-water crossings. The complete snorkel and intake system must be installed and checked for leaks before relying on it for water-ingress protection.
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.

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 ‘VOLT’ – DEFENDER SEATBOX JUMP-START & POWER PANEL
Anyone who has tried to jump-start a Defender with the battery under the passenger seat knows what a pain it can be—especially with dual batteries crammed into the seatbox.
Normally, you need to remove the passenger seat base, lift out the seatbox cover and then somehow get your jumper leads onto battery terminals that can still be extremely difficult to access.
The DEFAB Engineering ‘VOLT’ solves this problem by relocating heavy-duty positive and negative connection points to the outside of the passenger seatbox. This gives you quick, easy access whenever you need to jump-start your Defender—or use your Defender to help someone else.
The external terminals also make it quick and easy to connect a battery charger without having to remove the seat base or seatbox lid.
A handy Anderson plug is also incorporated into the panel, providing an easily accessible power supply for battery charging and lower-current 12V accessories such as a fridge.
The recessed terminal design helps protect the connections from accidental contact while keeping the installation neat, compact and out of the way.
FEATURES
Quick external access to positive and negative battery connections
No need to remove the passenger seat base or seatbox lid
Makes jump-starting your Defender—or another vehicle—far easier
Easily connect a battery charger through the Defab 'Volt' terminals
Particularly useful for Defenders with tightly packed dual-battery systems
Integrated Anderson plug for charging and (30a and below) 12V accessories
Recessed terminals for added protection
Neat installation into the side of the passenger seatbox
Main mounting panel printed from a specialised carbon-fibre-reinforced material
Supplied as a complete installation kit
Detailed installation video supplied to every customer after purchase
ANDERSON PLUG – 30A MAXIMUM (in-line fuse comes fitted to your VOLT unit)
The Anderson plug is intended for battery charging and lower-current 12V accessories such as a fridge etc. It has a maximum allowable load of **30 amps**.
**The Anderson plug must not be used for jump-starting or powering equipment drawing more than 30 amps. Jump-starting must only be carried out through the dedicated heavy-duty positive and negative terminals.**
INSTALLATION
Installation requires cutting an opening into the side of the Defender seatbox. Accurate measuring and competent installation are essential.
A detailed installation video is supplied to every customer who purchases the kit. If you are not confident carrying out the installation or working with high-current battery wiring, we recommend having it fitted by a suitably qualified automotive electrician or experienced workshop.
IMPORTANT
Vehicle and battery configurations vary. Please check the available space, cable routing and suitability for your particular Defender before installation.
Always isolate the battery before beginning any electrical work.
