How To Choose the Right Cold Air Intake for Your WRX

Do you want to feel the full potential of your WRX? Choosing modifications is always exciting, but it’s not about bolting the shiniest part onto your Subaru. While every modification matters, one of the most impactful upgrades you can make is the cold air intake. The right cold air intake can make a noticeable difference in the performance of your WRX.

Knowing how to choose the right cold air intake for your WRX is key to making the most out of your investment. In this guide, we’ll make it easy for you to understand which cold air intake option is best for you. Leave this read with the clarity and confidence you need to take the next step in your WRX’s performance journey!

Understanding How Cold Air Intake Works

Put simply, a cold air intake system replaces your WRX’s stock air intake with one that optimizes airflow. The idea is to draw cooler, denser air from outside the engine bay into the engine. Cooler air has more oxygen, which improves combustion power and efficiency.

Most stock air intake systems pull air from within the engine bay, where temperatures run significantly higher. Modifying your cold air intake system allows your engine to access air with better oxygen density, providing noticeable performance gains when paired with proper tuning.

Why the Right Cold Air Intake Matters

Your WRX is already an incredible machine, but a cold air intake can unlock better performance and help your engine breathe more easily. Upgrading your intake system could potentially lead to increased horsepower, torque, and improved efficiency. But it’s not just about choosing any intake system. Selecting the correct one ensures compatibility with your WRX and can prevent damage or inefficiencies in your engine's performance.

The wrong intake system, on the other hand, could lead to reduced performance or long-term engine issues. It’s crucial to weigh your options carefully so that your investment enhances your WRX while maintaining its reliability.

Types of Cold Air Intakes for the WRX

Short Ram Intakes

Short ram intakes are designed to be compact, replacing the stock intake with a shorter, straighter pipe. This setup enhances airflow and often yields a slight performance improvement.

However, because they draw air from within the engine bay, short ram intakes can be more susceptible to heat soak (where the air entering the system is warmer and less oxygen-rich). Short ram systems are generally simpler to install and tend to be more affordable.

True Cold Air Intakes

True cold air intake systems, as the name suggests, relocate the air filter outside of the engine bay, allowing your WRX to draw in cooler air. While this often results in greater performance gains compared to short ram systems, installation can be more complex.

True cold air intakes may also pose a risk of hydrolock (when water is sucked into the engine) if the filter is low and exposed to water sources, such as puddles.

Key Factors To Consider When Choosing a Cold Air Intake

Model Compatibility

Before making a choice, ensure the cold air intake you select is compatible with your specific WRX model year. Most of the intakes available for the WRX are short ram designs, even if they are marketed as cold air intakes. Manufacturers often engineer these systems with precise fitment and include heat shields or sealed airboxes to reduce exposure to hot engine air. For example, if you’re considering Subaru WRX aftermarket parts and cold air intakes, you’ll need to find an intake designed for your model to avoid installation issues.

Material Quality

The materials used in your cold air intake system impact its durability and performance. Look for intakes made from high-quality aluminum or carbon fiber, as these materials resist corrosion and help regulate air temperature. If you want to impress, titanium offers exceptional strength, is ultra-light weight, and has a standout visual appeal.

Filter Type

Filters come in two primary categories: oiled and dry. Oiled filters are reusable and designed to capture smaller particles, making them a great long-term investment. Dry filters, on the other hand, are easier to maintain but may not filter as effectively over time.

Performance Goals

What are you looking to achieve by upgrading your intake system? If you’re tuning your WRX for track performance, a true cold air setup might be ideal. If you're just looking for a slight boost in daily driving efficiency, a short ram intake may suffice. Mapping out your performance goals will help guide your decision.

Your Budget

Ultimately, your budget will play a significant role in determining which cold air intake to choose. While premium options with advanced features tend to provide better performance, there are also budget-friendly systems that offer reliable upgrades. Balancing cost with long-term value is key.

Tuning: Do You Need It After Installing a Cold Air Intake

After installing a cold air intake, it is highly recommended to tune your WRX. This is because your engine’s ECU (engine control unit) is calibrated for the stock intake system. A new intake system significantly changes airflow, and tuning ensures your engine is optimized for this alteration.

Failing to tune after installation could lead to imbalanced air-fuel ratios that reduce performance and possibly even harm engine components. Many WRX owners find that a professional tune unlocks the full benefits of their cold air intake upgrade.

Maintenance Tips for Cold Air Intakes

Maintaining your cold air intake is essential for consistent performance. Over time, dirt and debris can clog your air filter and restrict airflow. This negates the benefits of your upgrade. Make sure to:

• Clean or replace filters regularly: If your filter is washable, clean it according to the manufacturer’s guidelines.
• Inspect components for wear and tear: Check for cracks or loose connections that could compromise performance.
• Monitor for unusual performance issues: If you notice drops in efficiency or unusual engine noises, double-check your intake system for potential problems.

Choosing the right cold air intake for your WRX is a pivotal step in customizing your ride’s performance. With the right choice, this isn’t just an update. It’s the chance to elevate your entire driving experience, whether on the road or on the track.
