Direction Plus: Your Trusted 4WD Parts Supplier

By Steven Harrisson, October 13, 2025

Outfitting your ute or 4WD station wagon for the rigours of off-road driving comes with multiple challenges. Which gear works best? And how do different brands go about prepping your ride for off-roading fun? While dozens of parts brands promise more performance, lasting durability and improved handling when roads turn bad, few can match the engineering credentials of local parts maker Direction Plus. 

Based out of Perth, the company specialises in high-quality parts and accessories for diesel-powered utes and 4WDs, ranging from filtering kits and catch cans to throttle controllers and transmission coolers. 

Company Profile

Founded in 2003, Direction Plus is an Australian brand specialising in the design and production of advanced filtration systems for diesel engines. While most products are aimed at utes, SUVs and 4WDs, the company caters to all diesel-powered vehicles, including passenger cars, light and heavy-duty trucks and industrial and agricultural machinery. And with a well-established dealer network across the country, Direction Plus has the reach to ensure all parts are covered and backed by a dedicated team of experts. 

Why Choose Direction Plus Australia? 

The company has become the go-to choice for durability and performance in diesel vehicles. A key feature of Direction Plus products is the advanced filtration technology and state-of-the-art materials and construction techniques to remove contaminants from oil, fuel and air. For the demanding settings and uses that diesel vehicles endure daily, this reduces engine wear and damage, while boosting performance, cooling efficiency and fuel economy. 

How the aftermarket parts specialist stays above the competition is with local production. All parts and accessories are designed, engineered and assembled in Australia. Filtering kits are also rigorously tested in controlled lab settings to ensure they meet or surpass strict OE requirements. This secures compliance with ISO and SAE standards and provides proven reliability and engine longevity, no matter how or where you drive.

Preline-Plus Pre-filter Kits 

Pre-filtering kits from Direction Plus are the first line of defence against particle and water contamination. The Preline-Plus pre-filtering range is an innovative solution that ensures a high degree of water separation and particle pre-separation. Kits include an integrated water sensor that provides visual and audible alerts when water is present in the fuel. 

The dual-layer filtering media removes all water in the first layer, while the inner layer deals with particles, ensuring industry-leading filtering efficiency (100% for water and 98% for particles). Kits also benefit from simple spin-on installation for hassle-free filtering.

Ryco Pre-filter Kits

These are designed specifically for high-pressure (87 psi/6 bar) diesel systems with lift pumps on the tank. Kits consist of 10-micron filtering media, removing 99% water and 98% particles in diesel fuel, and providing maximum efficiency, flow and longevity for your engine. Located before the main filter, Ryco Pre-filtering units keep critical engine components clean and damage-free. To up monitoring functionality, also consider pairing the kit with Direction Plus’ Wireless Sensor Kit and enjoy a true fit-and-forget experience without the need for manual inspections. 

Fuel Manager Pre-filter Kits

This misses out on water sensors and electrical alerts, but comes with single-layer filtering media that removes 95% water and particles, as well as the ability to separate emulsified water from Ultra-Low Sulphur Diesel (ULSD) and prevent rust and contamination. Kits are also designed to prevent filter bypass, even when the filter is blocked, preventing contaminated fuel from reaching the engine. 

Fuel Manager Post-filter Kits

These are fitted between the engine and OEM fuel filter to remove remnant water and particles not picked up by the factory filter. Fuel Manager Post-filter kits consist of 2 or 5-micron filtering assemblies, a clear drainage water bowl, stainless steel mounting brackets, fuel hoses, fasteners and clamps. Like all Direction Plus pre- and post-filtering kits, they’re vehicle-specific for carefree installation and prevent the likelihood of fuel contamination and costly engine damage. 

ProVent Catch Cans 

ProVent catch cans separate and redirect oil and air from blow-by gas in the crankcase. At its core is the ProVent 200 oil separator, with additional hardware consisting of stainless steel mounting brackets, hoses and fittings and a small drain kit to facilitate draining. Kits are designed to prevent oil and soot contamination in the air intake, ensuring engines run efficiently and smoothly. Separators also keep turbos in top condition, keep oil use down and save money and time without the need for frequent oil changes. 

TransChill Automatic Transmission Cooler Kit

The TransChill is an auxiliary cooling system used in automatic transmissions. It’s designed to keep excessive heat at bay, for instance, when towing or hauling heavy loads. Installing a TransChill kit helps lower transmission fluid temperatures and ensures the efficiency and longevity of the transmission. The cooler works by using ambient air and plate-and-fin coolers with high-efficiency turbulators to enhance heat transfer. 

Summing Up

Direction Plus Australia also provides throttle controllers for all major ute, 4WD, and SUV makes and models sold in the country, as well as a wide selection of 4×4 accessories (battery trays, lights, recovery tow points, tyre deflators and repair kits and underbody protection) for safe, cosy and hassle-free motoring on and off-road. The company’s filtering systems and catch cans thoug,h remain its core business, with products distributed nationwide.
