Since it’s inception, the Terracan has captured the essence of adventure and off-road capability.

Produced between 2001 and 2007, the Terracan has gained a reputation as a reliable SUV suited for various terrains and conditions.

The Terracan was offered with two engine options: a 2.9L CRDi turbo-diesel engine and a 3.5L V6 gasoline engine.

Combining durability, performance, and practicality, the Terracan remains a strong contender in the used vehicle segment for adventure seekers and off-road enthusiasts.

While a capable car in standard form, many owners look for ways to further it’s capabilities. This can be through increasing the power or through exterior cosmetic upgrades like a suspension lift or bull bar.

In this article we’ll go over all the best ways to modify and tune your Terracan for maximum practicality and enjoyment. 

Aftermarket Exhaust

A performance exhaust system is designed to enable better airflow through the engine, allowing it to breathe more efficiently and reducing exhaust back-pressure.

They also produce a deep sportier rumble as well which is very pleasing. 

You won’t get significant power improvements from fitting an aftermarket exhaust alone, however a performance exhaust combined with a remap can definitely make a large difference. 

Due to the age of some of the older Terracan models and their exposure to salt and harsh environment when off-roading, many of the original exhaust systems are starting to wear and rust. If yours is like this, then this can be a great opportunity to opt for a sporty upgrade.

For the best sound increase, you will want to upgrade the “cat-back” section of the exhaust. This will give you a nice increase in sound without affecting emissions.

The cat-back section of the exhaust refers to the point of the exhaust after the catalytic converter and replaces the standard muffler/backbox.

Performance Air Filter

Performance air filters provide an enhanced flow of clean air to your engine, and this improved circulation results in better combustion, effectively increasing horsepower.

Many owners notice improved acceleration and throttle response.

Unlike standard air filters that require replacements every service, high-performance air filters are reusable. They are designed for durability, withstand extreme conditions, and can be cleaned and reinstalled, contributing to their longevity and cost-efficiency.

This is also a mod that doesn’t require much technical knowledge to install. 

Fitting a performance air filter is often straightforward and can usually be done in minutes at home. Most models come with step-by-step installation guides to make the process hassle-free.

K&N make great high quality filters so definitely check them out. 


Optimizing engine performance through a remap has become an increasingly popular practice among vehicle owners, and the Hyundai Terracan is no exception.

In case you don’t know, a remap optimizes the various parameters of the ECU to help boost power and torque and in some cases fuel economy. 

The main benefit from a remap to the Terracan is the extra torque you can gain. 

When it comes to tackling rugged terrains, extra torque is a significant advantage. More torque will enable the Hyundai Terracan to power through muddy fields, steep hills, and rocky paths with ease, making your off-road adventures more thrilling and less strenuous.

Extra torque is also particularly valuable for towing or hauling weighty loads. Whether you’re pulling a caravan, trailer, or transporting heavy equipment, increased torque can make a massive difference.

So you how much power can a remap unlock?

From a remap alone with no supporting mods on the 2.9 CRTD that makes roughly 160bhp from the factory – you can achieve over 30bhp and over 70lb-ft of torque!

Definitely the best value mod if you are looking for a bit of extra power.

Suspension Lift

A suspension lift can equip the Terracan with the extra edge required for off-roading, as well as various other benefits like better visibility and easier access underneath the car.

By raising the suspension height, you increase the approach angle and departure angle.

These improved angles enable the Terracan to approach steeper hills, clear larger objects, and prevent the undercarriage from getting stuck or damaged during off-road escapades.

The most common lift height is 2 inches with some opting for a 3 inch lift on the extreme end. 

Bull Bar

The primary benefit of a bull bar is the enhanced safety. By adding an extra level of protection, a bull bar shields the front end of your Terracan from the impact of minor collisions, reducing potential damage. This is especially useful if you live in areas with a high wild animal population.

If you frequently drive off-road, a bull bar also provides better clearance and improves the Terracan’s capability to navigate rugged terrains. This means better protection for vital components such as radiator or headlights against common off-road hazards like rocks or bushes.

Additionally, it also serves as a mounting point for accessories such additional lights. If you are into night adventures or remote area travels, adding spotlights or fog lights can drastically improve visibility.


Aside from giving your Terracan a mean off-road look, a snorkel intake offers benefits that are very important if you like your off-road adventures and tend to encounter standing water.

By fitting a snorkel kit, the Terracan intakes air from roof-level which is cleaner and dust-free compared to air at bonnet level. This will especially benefit you if you’re off-roading in dusty conditions, as it prevents dust ingestion into the engine. 

Of course, the main benefit is the enhanced water crossing abilities it gives your car.

By rerouting the Terracan’s air intake to a higher point, the snorkel allows the engine to breathe safely when faced with water crossings, ensuring no water enters the engine which may cause severe damage or hydrolock.
