Why Upgrade to a Cold Air Intake on Your 2020 Jeep Gladiator?
If you own a 2020 Jeep Gladiator, you already know it’s a capable machine—built for adventure, towing, and daily driving. But even the best trucks can benefit from a few performance upgrades. One of the most effective and affordable mods is installing a cold air intake (CAI). This simple upgrade can unlock hidden power, improve efficiency, and give your Gladiator a more aggressive personality.
So, what exactly does a cold air intake do? In short, it replaces the factory air intake system with one that pulls in cooler, denser air from outside the engine bay. Stock intakes often draw in hot air from around the engine, which reduces combustion efficiency. A cold air intake routes air from a cooler location—usually near the fender or bumper—delivering more oxygen to the engine. More oxygen means better combustion, which translates to more power and responsiveness.
But it’s not just about horsepower. A quality cold air intake can also improve throttle response, making your Gladiator feel more lively when you press the gas. Many drivers notice a deeper, more satisfying engine sound, especially during acceleration. Plus, some systems are designed to increase airflow efficiency, which can lead to slight improvements in fuel economy—especially on long highway drives.
Benefits Beyond Performance
Beyond the performance gains, a cold air intake offers practical advantages. Most aftermarket systems use high-flow, reusable filters made from cotton gauze or synthetic materials. These filters can be cleaned and reused hundreds of times, saving you money compared to replacing disposable paper filters every 12,000 to 15,000 miles.
Another benefit is durability. Off-roading puts your Gladiator through tough conditions—dust, mud, water crossings, and extreme temperatures. Many cold air intakes are built with heat shields and sealed housings to protect the filter from engine heat and debris. Some even include water-resistant coatings or pre-filters to keep dirt and moisture out.
And let’s not forget aesthetics. A well-designed cold air intake can give your engine bay a cleaner, more aggressive look. Many systems come with polished aluminum or powder-coated components that stand out under the hood.
How a Cold Air Intake Works

To understand why a cold air intake makes such a difference, it helps to know how your engine breathes. Your Gladiator’s engine is essentially a giant air pump. It needs a steady supply of air to mix with fuel for combustion. The more air it can take in, the more power it can produce.
The factory air intake system is designed for quiet operation, emissions compliance, and cost efficiency—not maximum performance. It typically pulls air from inside the engine bay, where temperatures can soar. Hot air is less dense, meaning it contains fewer oxygen molecules. Less oxygen equals less efficient combustion and reduced power.
A cold air intake solves this problem by relocating the air filter to a cooler, more open area—often near the front grille or wheel well. This allows the system to draw in ambient air, which is cooler and denser. The intake tube is also usually wider and smoother than the stock version, reducing airflow restrictions.
The Science of Air Density
Air density plays a crucial role in engine performance. Cooler air is denser, so each intake stroke brings in more oxygen. More oxygen allows for a richer fuel mixture and more complete combustion. This results in a noticeable increase in horsepower and torque, especially in the mid-to-high RPM range.
For example, a 2020 Jeep Gladiator with the 3.6L Pentastar V6 engine produces around 285 horsepower and 260 lb-ft of torque from the factory. While a cold air intake won’t double that number, it can add 5 to 15 horsepower and a similar amount of torque, depending on the system and tuning. That might not sound like much, but it’s enough to feel a real difference in acceleration and towing capability.
Real-World Performance Gains
Let’s put this into perspective. Imagine you’re towing a small trailer up a steep hill. With a cold air intake, your engine doesn’t have to work as hard to maintain speed. The improved airflow helps keep combustion efficient, reducing strain on the engine and transmission.
Or picture yourself off-roading in the desert. Dust and heat are constant challenges. A sealed cold air intake with a high-flow filter ensures your engine gets clean, cool air even in harsh conditions. This can prevent power loss and reduce the risk of overheating.
Even in everyday driving, the benefits are noticeable. You’ll experience quicker throttle response when merging onto the highway or passing another vehicle. The engine feels more responsive, and the deeper exhaust note adds to the driving experience.
