Cold Air Intake for Ford Ranger B4000 (2004-2011) 4.0L Engine

Optimize Airflow and Throttle Response for the Ford Ranger Cologne V6

Who It’s For: Designed specifically for Ford Ranger and Mazda B4000 owners running the 4.0L Cologne V6 engine. Whether you’re using your truck as a daily workhorse or a weekend trail rig, this intake is for drivers who want better mid-range pull and a more responsive pedal.

The Problem: The factory airbox on the Cologne V6 is built for sound suppression, not performance. It uses a restrictive, corrugated plastic intake tube that creates air turbulence and traps heat. This causes the engine to struggle for breath, especially under load or in high-temperature environments, leading to sluggish acceleration and decreased efficiency.

The Solution: We engineered this cold air intake to replace the narrow factory plumbing with high-flow T304 aluminum piping. By smoothing the path to the throttle body and utilizing a high-velocity cone filter, we significantly reduce intake air temperatures and air resistance. This allows your 4.0L SOHC to breathe freely, correcting the factory design flaws and providing a noticeable bump in power and a deeper engine note.

Why This is the Ultimate Upgrade

• Enhanced Velocity: Mandrel-bent T304 aluminum piping ensures a smooth, consistent air stream, increasing horsepower and torque by up to 10% across the power band.
• Superior Filtration: Features a washable, high-flow blue cone filter that provides exceptional filtration while allowing maximum air volume. It only requires servicing every 50,000 miles.
• Direct Bolt-On Fit: No cutting or drilling required. This kit is designed to utilize existing mounting points, allowing for a clean installation in less than 60 minutes with basic hand tools.
