Universal High-Flow Air Filter

Give your engine the airflow it deserves with this reusable, high-performance air filter—perfect as a direct replacement for an ECS intake system or as the finishing touch for your custom intake project.
Dimensions: 4.5" Base OD • 6" Filter Height • 3.5" Top OD

Upgrade from your restrictive factory filter to an ECS Tuning High-Flow Dry Air Filter and let your engine breathe freely. Improved intake flow enhances power throughout the rev range while helping maintain efficient fuel economy.

Oiled vs. Dry Filters — Which Is Right for You?

Oiled Filters

Offer slightly higher airflow for maximum performance

Require more frequent cleaning

Must be re-oiled after each cleaning

Long-term reusable design saves money over disposable paper filters

Dry Filters

Provide excellent airflow with minimal maintenance

Easily cleaned with warm, soapy water—no oiling required

Still flow significantly better than OE paper filters

Fully reusable and cost-effective

Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.

Ensure optimal engine performance with the replacement of your vacuum system hoses. The vacuum system plays a crucial role in the engine's functionality, transforming it into an efficient pump that influences air-fuel mixture and combustion. Damaged vacuum hoses can lead to various performance issues, from rough idle to difficulties starting the engine. If you're experiencing these issues, it's time to upgrade to this plastic hose with a 2.3mm inner diameter. The hose is black, arrives in an 8-foot section, and can be easily cut to the desired size for a perfect fit.

Key Features:

• Engine Optimization: Replacing old hoses ensures the vacuum system operates at peak performance.
• 2.3mm Inner Diameter: Designed to meet specific engine requirements.
• Black Color: Blends seamlessly with the engine components.
• 8-Foot Section: Provides flexibility to cut the hose to the required length.
• Easy Installation: Upgrade without hassle for improved engine efficiency.

Upgrade your vacuum system with this high-quality plastic hose, addressing performance issues and ensuring your engine runs smoothly.

The S55's factory intake system is a major bottleneck, muting its aggressive twin-turbocharged soundtrack and restricting performance. Oversized airboxes, restrictive paper filters, and charcoal pre-filters choke airflow, limiting power and induction noise. The result? An underwhelming driving experience that doesn’t do the twin-turbo-six justice.

ECS aims to solve this issue with their Luft-Technik Performance Intake System—engineered to optimize airflow, amplify induction sound, and completely transform your engine bay. By replacing the factory restrictions with a high-flow design, this system unleashes the S55’s true potential, delivering sharper throttle response, enhanced turbo efficiency, and an intoxicating intake note.

At its core, the Luft-Technik intake is comprised of dual aluminum inlet tubes, designed for both strength and function. Constructed from 6061 aluminum and finished in a wrinkle black powder coat, these tubes are built to withstand high engine bay temperatures and extreme conditions. Using advanced CAD modeling, ECS engineers optimized the tubing shape to ensure perfect MAF sensor scaling, maintaining factory AFR (air-to-fuel ratio) for peak reliability and efficiency. The unique ovular profile maximizes clearance around critical engine components while allowing for the largest possible inlet diameter. The crossover tube features standoffs for secure heat exchanger hose mounting and a CNC-machined 6061-T6 billet aluminum MAF flange and vacuum port, ensuring seamless integration with factory connections.

To prevent heat soaking and maintain consistent performance, our intake system incorporates precision-cut aluminum heat shields. Finished in a durable wrinkle black powder coat, the heat shields feature a rubber edge trim that seals against the hood, preventing engine bay heat from infiltrating the air intake tract. This results in lower intake air temperatures (IATs), improved air density, and overall improved performance even under demanding conditions.

Key Features:
