    Why Buy from CPP Diesel

    • Common-Rail focus: We stock parts that package and sensor-fit correctly on 2003–2007 5.9L trucks.
    • Choice of media: Oiled performance cotton or maintenance-friendly dry elements.
    • Everything in one box: Sealed intakes, BHAF options, wraps, scoops, and service kits.
    • Expert support: We’ll help you match intake style to towing, street, or competition use.

    Round out airflow with intake manifolds & boost tubes and intercoolers & piping.

    Helpful Notes

    • Oiled vs. Dry: Oiled filters flow great; dry media simplifies maintenance and MAF-sensor concerns on other platforms.
    • BHAF sizing: Most BHAF options here use a 4" inlet; measure your tube before ordering.
    • Sealed vs. open: Sealed boxes (S&B, Banks, aFe Momentum) reduce heat-soak at low speeds; open tubes emphasize sound and serviceability.
    • Service intervals: Use wrap/pre-filter in dust or snow; clean/re-oil (oiled media) or blow-out/replace (dry) per conditions.

    Frequently Asked Questions

    What’s the easiest intake upgrade for a daily-driven 5.9L?

    A sealed, bolt-on system like S&B 75-5094D or aFe Momentum HD 51-72002 for lower intake temps and easy servicing.

    BHAF vs. boxed intake — which is better?

    BHAFs (e.g., aFe 21-90097) offer huge surface area and simplicity; boxed systems (S&B, Banks, aFe Stage-2) shield heat better and integrate factory ducting.

    Do I need a tune after installing an intake?

    No tune required for these bolt-on systems. For performance builds, pair with monitoring/tuning in our 03–07 Tuners / Chips / Monitors.

    Should I add a pre-filter or scoop?

    In dusty or wet climates, a wrap helps extend service intervals; a Super-Scoop can improve ram-air effect at speed with Banks systems.
