Cold Air Intake for Mazda B4000 (2001-2003) 4.0L V6 Engine - Blue

Tired of your Mazda B4000 feeling a bit breathless when you hit the gas, especially with a load? That sluggish feeling from the factory intake can really dull the driving experience, but there’s a straightforward fix that’ll make your truck feel much more responsive.

Performance Cold Air Intake for Mazda B4000 (4.0L V6)

From the factory, your 2001-2003 Mazda B4000’s 4.0L V6 came with an air intake system designed for quiet operation and cost-effectiveness, not peak performance. This often means a restrictive airbox, corrugated intake tubing, and internal resonators that create turbulence and choke the engine, limiting its ability to pull in the cold, dense air it craves for optimal combustion. It’s like trying to run a marathon while breathing through a straw.

This high-flow cold air intake system completely re-engineers that pathway. By replacing the stock bottlenecks with smooth, wide-diameter T-304 aluminum tubing and a high-efficiency conical air filter, we’re allowing your 4.0L V6 to breathe freely. This means a direct, streamlined shot of colder, more oxygen-rich air straight to your throttle body, resulting in a noticeable improvement in power, throttle response, and even that characteristic V6 growl when you lean into it.

Why You Need This Upgrade

• Enhanced Torque & Pulling Power: Notice a stronger pull off the line and when climbing grades. The improved airflow helps your 4.0L V6 generate more usable torque, whether you’re hauling gear or just commuting.
• Sharper Throttle Response: Gone is that slight hesitation. With less restriction, your engine reacts more quickly to pedal inputs, making daily driving feel more engaging and less like you’re waiting for power.
• Measurable Horsepower Gains: Real-world testing shows these engines respond well to better airflow. You’ll feel a tangible bump in mid-range and top-end power, making highway passing or merging smoother.
• Improved Fuel Efficiency (with careful driving): By optimizing the air-to-fuel ratio and combustion efficiency, many drivers report a slight uptick in MPG under normal driving conditions. It’s not a miracle cure, but better breathing helps.
• Durable, Lightweight Construction: Crafted from T-304 aluminum, this intake tubing isn’t just for show. It’s built to last, resists corrosion, and helps dissipate heat more effectively than plastic, keeping intake air temps down.
• Aggressive Engine Sound: Let’s be honest, part of the fun is hearing that V6 growl. This intake provides a deeper, more aggressive tone, especially under acceleration, without being obnoxious at cruise.
