Sealed Airbox Design:

The COBB intake features a sealed airbox that draws cool air from outside the engine bay, similar to the factory design but with dramatically improved flow. This sealed design prevents heat soak by isolating the filter from engine heat, ensuring the engine receives cool, dense air for maximum power. The airbox is engineered to fit perfectly in the factory location using factory mounting points.

High-Flow Oiled Cotton Filter:

COBB uses a premium oiled cotton filter that provides exceptional airflow while maintaining excellent filtration. The oiled cotton design captures particles more effectively than dry filters while flowing significantly more air than the factory paper filter. The filter is washable and reusable - simply clean and re-oil every 30,000-50,000 miles for continued performance.

Mandrel-Bent Aluminum Tubing:

The intake tube is mandrel-bent from aluminum to maintain consistent internal diameter throughout each bend. This eliminates the crimping and restriction that occurs with crush bending, ensuring smooth, unrestricted airflow from the filter to the turbo inlet. The powder-coated black finish resists corrosion and maintains a clean appearance in your engine bay.

Proven Power Gains:

Dyno testing shows the COBB intake delivers +20 HP and +30 lb-ft torque on a stock Focus ST. These gains come from the improved airflow and reduced restriction compared to the factory airbox. When combined with other modifications (downpipe, intercooler, tune), the gains are even more significant as the intake supports higher power levels.

Aggressive Intake Sound:

One of the most satisfying benefits of the COBB intake is the aggressive intake sound. You'll hear the turbo spooling, the blow-off valve venting, and the engine breathing deeply during acceleration. The sound is aggressive but refined - not obnoxiously loud, but definitely noticeable and enjoyable.

Essential for Stage 2+ Tuning:

If you're planning to install a downpipe and run Stage 2 or higher tuning, the COBB intake is an essential upgrade. The factory airbox becomes a major bottleneck on modified engines, limiting power gains and increasing risk of running lean. The COBB intake ensures your engine receives the airflow it needs for maximum performance and reliability.

Why COBB Tuning?

COBB Tuning has been engineering high-performance parts for Ford EcoBoost engines for over 15 years. Their intakes are designed using advanced CAD software and tested extensively on dyno and track to ensure optimal performance, fitment, and reliability. Every COBB intake is manufactured to strict quality standards and backed by their industry-leading support.

Filter Maintenance:

The oiled cotton filter should be cleaned and re-oiled every 30,000-50,000 miles depending on driving conditions. Cleaning is simple:

1. Remove filter from airbox
2. Spray with filter cleaner and let soak
3. Rinse with water from inside out
4. Let air dry completely
5. Apply filter oil evenly
6. Reinstall filter

Perfect Pairing:

For maximum performance, pair the COBB intake with:

• COBB Accessport for optimized tuning
• COBB downpipe for Stage 2 tuning
• Upgraded intercooler for lower intake temps
• Cat-back exhaust for complete exhaust system

Installation Tips:

• Allow engine to cool before starting installation
• Take photos during disassembly for reference
• Ensure all clamps are tight to prevent boost leaks
• Check for proper clearance around moving parts
• Test drive and listen for any unusual sounds
• Get an Accessport tune to optimize for the intake

Sound Level:

The COBB intake delivers an aggressive intake sound that enhances the driving experience:

• Idle: Minimal change from stock
• Cruising: Subtle turbo spool audible
• Acceleration: Aggressive turbo spool and intake noise
• Blow-Off: Enhanced BOV sound during shifts

Perfect For:

• Focus ST owners seeking proven power gains and aggressive sound
• Stage 2+ builds requiring better airflow
• Track day enthusiasts needing maximum performance
• Daily drivers who want improved throttle response
• Anyone wanting to hear their turbo spool

Perfect For: Focus ST owners seeking proven power gains, aggressive intake sound, and improved throttle response with a direct bolt-on upgrade.

Pro Tip: Pair with a COBB Accessport and Stage 1+ map to fully optimize for the intake - you'll unlock even more power and better drivability.
