Cold Air Intake for Mazda B-Series (1998-2001) 3.0L

High-Flow Cold Air Intake for 1998-2001 Mazda B-Series (PN105)

What it Does: The Cold Air Intake replaces the restrictive factory airbox and corrugated ducting on the 1998-2001 Mazda B-Series to deliver cooler, denser air for improved throttle response and increased mid-range torque.

The Stock Mazda B-Series Intake Restriction

Factory intake plumbing on the PN105 chassis relies on accordion-style rubber flex-tubes and baffled resonator chambers designed primarily for sound suppression rather than volumetric efficiency. Under sustained engine loads, these corrugated inner walls create boundary-layer aerodynamic drag and localized turbulence upstream of the mass air flow sensor. Additionally, the enclosed plastic airbox draws pre-heated air trapped in the engine bay, increasing intake air temperatures (IAT) and reducing ignition timing advance on the 3.0L Vulcan V6.

The Engineering Solution

This performance intake system integrates smooth-bore, mandrel-bent T-304 aluminum piping with a polished thermal barrier finish to reduce parasitic heat soak. Paired with a high-flow, oil-free conical dry air filter, the system straightens intake velocity profiles and reduces pressure drops across the induction tract. The result is a sharp increase in low-to-mid RPM throttle response, an authoritative induction note, and measured output gains of approximately 7-10% horsepower and 6-8% torque across the operating band.

Frequently Asked Questions & Fitment Warnings

Does this fit the PN105 B-Series?

Yes, this is a direct bolt-on fit for the 1998-2001 Mazda B-Series equipped with the 3.0L Vulcan V6 engine. This kit does not fit 2.5L Inline-4 or 4.0L V6 models.

Does this kit require an aftermarket ECU tune?

No, this intake maintains stock sensor diameters to retain proper air-fuel ratios without triggering a Check Engine Light (CEL).

The Mazda Truck Standard

Engineered for rugged daily work and demanding towing conditions, this intake system provides the structural durability and thermal resistance needed to maintain optimal engine efficiency across high-load truck applications.
