4x4 Performance Upgrades Perth
Unlock Your 4WD’s Potential

Want more power, torque or efficiency from your 4WD? Coastals 4×4 offers a suite of 4×4 performance upgrades in Perth to enhance your vehicle’s engine breathing, tuning, and overall output. Whether it’s fitting a snorkel for cleaner air intake, a performance exhaust for freer flow, or an ECU remap for optimized power delivery, our expert team can transform your driving experience. We work with reputable brands like Safari, TaipanXP, and local tuning specialists to ensure safe, reliable gains. From diesels to petrol 4x4s, daily drivers to off-road beasts, we’ll tailor a performance package that delivers noticeable improvements while maintaining durability for long Australian journeys.

Snorkels
Raise Your Intake

A Safari snorkel or similar elevated intake is often the first performance mod for off-road vehicles. It has multiple benefits:

  • Cleaner, Cooler Air: By drawing air from roof level, a snorkel provides your engine with less dust-laden and cooler air. On dusty convoy drives in WA or the red dirt of the Pilbara, having a snorkel can dramatically reduce how often your air filter clogs. Cooler intake air also aids in better combustion efficiency. We supply leading snorkel brands like Safari (known for tough, UV-stable polyethylene construction) and Airflow.

  • Water Crossing Ability: The iconic reason for a snorkel – protecting your engine during water crossings. The raised intake helps prevent water from being sucked into the engine when fording rivers or flood tracks. (Important: we’ll remind you that other vehicle prep is needed for deep water like diff breathers, but the snorkel is step one).

  • Performance Intake Kits: For some models, we also offer sealed performance air intake kits (such as the Safari R-MAX or K&N systems) that claim higher airflow than stock. These can pair with snorkels or be standalone for those seeking a small power bump and enhanced induction sound.

Our installation is clean, using the template and cutter for precise fender hole creation, rust-treating all cuts, and secure mounting. We ensure all connections are watertight with proper silicone so your snorkel isn’t just cosmetic – it’s functional when it counts.

Performance Exhausts

Upgrading the restrictive factory exhaust on your 4×4 can yield gains in power and economy, especially on turbo-diesels. We offer:

  • High-Flow Exhaust Systems: Typically in 3″ mandrel-bent piping (stainless or aluminized steel), these exhausts reduce back-pressure. Brands like TaipanXP, Redback and Torqit craft systems for popular models. With a larger diameter and free-flow mufflers (or muffler deletes), your engine can exhale easier. The result is often a crisper throttle response and a few extra kilowatts, plus a deeper exhaust note that sounds great without being too loud.

  • DPF-Back or Turbo-Back: We do both styles depending on whether your vehicle has a Diesel Particulate Filter (DPF). For newer DPF-equipped 4WDs, we replace from the DPF back. For older ones, a full turbo-back system with a high-flow cat converter can maximize gains. We ensure all components (flex joints, mounts) are high quality for longevity on corrugated roads.

  • Headers (Extractors): On some petrol 4x4s (like the Toyota 4.0L V6 or older carbureted engines), fitting performance headers can improve the engine’s breathing significantly. We can install extractors from brands like Pacemaker, which often pair with a 2.5″ system to give solid torque gains in the mid-range.

Every exhaust we fit is aligned properly to avoid rattles and clear all chassis components. We also take care that tailpipes exit in the factory location or a sensible position to avoid gas entering the cabin (especially on wagons).

ECU Remapping & Chips

Modern 4WDs have a lot of potential locked in their engine computers. Through ECU remapping, we can safely tune your engine for more power and often better fuel efficiency. We work with reputable tuning partners (with dyno testing) to offer:

  • Custom ECU Remaps: By adjusting fuel delivery, boost (if turbo), and timing maps, a remap can yield 20-30% more power and torque on many turbo-diesel 4x4s. For example, a common-rail Hilux or Ranger can see impressive gains, especially when combined with the snorkel and exhaust mentioned above (the trio of exhaust, intake, tune is a proven recipe). We ensure tunes are conservative and safe, prioritizing reliability for touring. No sky-high EGTs or overstressed components – we target a balance where your vehicle runs optimally within its design limits.

  • Throttle Controllers: While not a direct power adder, many customers love devices like the iDrive or Windbooster. We can fit these to sharpen throttle response (reducing that factory lag) which makes the vehicle feel more eager. It’s a plug-in mod and we’ll show you how to use its modes effectively.

  • Plug-in Chips: Alternatively to a remap, we can install plug-in tuning chips/modules (e.g. Steinbauer, Safari ARMAX module). These intercept signals to bump up fuel rail pressure or injector duration and often are user-adjustable. We generally favor ECU remapping for a tailored result, but we can accommodate chip preferences too, especially if the client wants the ability to remove it for dealer servicing, etc.

Rest assured, we approach tuning carefully: we often perform a pre-tune inspection (making sure the engine, turbo, and transmission are all healthy) so that the extra power won’t exacerbate an underlying issue. After tuning, many customers report their 4WD is more enjoyable to drive – less downshifting on hills, overtaking with ease, and even a small improvement in fuel economy due to increased efficiency (as long as you’re not lead-footing all the time with the newfound power!).

Other Upgrades

As a full service 4×4 shop, we can also advise on and install other performance-oriented mods:

  • Upgraded Intercoolers: Keeping the intake air cool is critical for making power. We can fit larger or more efficient intercoolers (front-mount or top-mount with better cores and fans) for turbo-diesels, ensuring sustained performance on long sand dunes or when towing.

  • Fuel System & Injectors: We handle upgrades like higher-flow injectors or lift pumps if you’re going to extreme levels (often more relevant for competition or very heavy towing builds). We can also simply refresh your injectors if they’re old – often restoring lost power in older diesels.

  • Clutch Upgrades: With more power, manuals might need a stronger clutch. We can upgrade to heavy-duty clutch kits that handle the extra torque without slipping, while keeping pedal feel reasonable for daily driving.

  • Dyno Testing: If desired, we can coordinate before-and-after dyno runs with our tuning partners to quantify the gains. Some of our package tunes come with dyno sheets so you can see the power/torque curves and know exactly what you gained.

Proven Results, Safe Modifications

Coastals 4×4 takes pride in delivering proven performance upgrades that don’t compromise your vehicle’s longevity. Everything we do is reversible if needed and within legal requirements (for example, we don’t delete emission equipment). Our knowledgeable staff will walk you through each recommended upgrade, explaining the pros, any maintenance implications (like “oiled” performance air filters needing cleaning), and expected outcomes.

We love hearing customers come back from a trip saying how their tuned and snorkeled Cruiser tackled big hills with ease, or how their Navara with the new exhaust is sipping less fuel while cruising. Those success stories drive us to keep offering top-notch performance enhancement services.

Unleash your 4WD’s capabilities with the performance upgrades Perth off-roaders trust.
