Why Your Airbox Is Critical When Driving in Harsh Conditions
Most people might not be aware that the vehicle’s airbox has a critical role to keep especially when driving in demanding environments. Basically, the airbox is used to house and protect the air filter of your vehicle, which will ensure the engine can get clean, controlled airflow. A custom airbox, for instance, will not only support engine performance but also take part in the prevention of costly wear caused by fine dust and contaminants.
Types of Airboxes and How They Make an Impact
- Factory Airbox
This type of airbox is designed by manufacturers for balanced performance, efficiency, and noise control. Its impact on performance includes stable, consistent airflow, excellent filtration, and optimised for fuel economy and emissions.
- Sealed Aftermarket Airboxes
The upgraded version of factory systems is often larger with improved airflow design. Its impact on performance includes better airflow than stock, improved throttle response, and stronger protection in dusty environments. This is ideal for touring, towing, and 4WD use.
- Open Pod/ Exposed Filters
This type of filter sits openly in the engine bay without a sealed box. As a result, it will cause louder induction sound, reduce performance due to hot air intake, and often poorer filtration in dusty conditions. This may be popular for sound, but not always ideal for harsh climates.
- Cold Air Intake Systems
This will draw air from the outside of the engine bay in order to reduce the intake temperatures. This can impact the performance by providing cooler, denser air to improve combustion efficiency. You will get potential gains in power and torque, particularly when properly sealed.
- Heavy-Duty 4WD Airbox
This is built for extreme dust and water resistance, which in turn maintains airflow in harsh conditions. Likewise, it can extend the engine life, while reducing filter clogging. In Australia, a sealed or heavy-duty system often provides a good balance of protection and performance.
Signs Your Vehicle’s Airbox Needs to Be Replaced
- Cracks or Physical Damage
You can inspect the airbox housing to see if there are visible cracks, warping from heat, or broken clips or seals. If this is so, your engine might already be receiving unfiltered air, causing long-term damage.
- Excessive Dust Inside the Airbox
Check if there is dust getting beyond the filter area. You can start by looking into the air filter first. The dust inside the intake pipe means that the airbox seal may be compromised.
- Poor Engine Performance
After noticing your vehicle is getting sluggish acceleration, rough idling, or reduced fuel efficiency, it might be a sign that your airbox is failing. It might be restricting airflow or leaking, which causes the drop in combustion efficiency.
- Unusual Intake Noise
If you hear a louder-than-normal suction sound in your engine bay, it may be indicative of loose housing, cracked box, or poor sealing.
Don’t wait for the engine to fail just because you neglect to check its last line of defence against dust, dirt, and contaminants. Contact Torqit if you want to know the impact of a custom airbox on your 4WD vehicle.
