    Roush Performance 421238 - Roush Performance Cold Air Intake Kits

    Upgrade your Ford Mustang, Ford Focus, or Ford F-150/F-250/F-350 with a Roush Cold Air Intake Kit to unleash additional horsepower and torque and increase efficiency. These kits include a custom high-flow ROUSH® air filter with clamp, MAF tube, air box tray with installed EPDM foam hood seal, and mounting hardware.

    Cold air induction is a more efficient air intake method than the standard air filtering process. As a result, cold air induction can unlock the potential in power and fuel efficiency that is normally restrained by a stock air intake unit.

    The benefits of these kits include reduced pressure drop and increased performance and efficiency. Both the tray and MAF tube are manufactured using OE-quality materials (30% glass-filled polypropylene) and tooling (fully CNC machined hardened steel plastic injection molds). These provide excellent dimensional capability, stability, and lasting performance.

    These systems have been engineered and tested to ensure MAF signal performance (including airflow vs. voltage and signal noise) is transparent to factory settings, which is why Roush kits do not require a unique calibration. Furthermore, these kits use factory mounting locations and hardware and maintain OE clearances for simple installation.

  • Increased horsepower and torque
  • Improved fuel mileage
  • Simple installation (no drilling or cutting)
  • No PCM calibration required (unless noted)

    Rated 4 out of 5 by from Noticeable power increase Other than the clips that replace the air filter cover clips not holding this product is amazing. Easy to install although the instructions are vague and near useless. Would definitely recommend as an upgrade.
