Product Description

Mustang Throttle Body Spacer
Increase throttle response, low-end torque, and mid-range power with this 2011-2021 Mustang 5.0 throttle body spacer! Airaid built this Poweraid throttle body spacer to enhance off-idle torque from 800rpm to 3,000rpm. They utilize a patented, Helix Bore design that spins the incoming air as it passes through the spacer. The spinning boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture. This results in increased performance for your Mustang!

Airaid Quality
Airaid constructs this Poweraid throttle body spacer with aircraft quality 6061-T6 billet aluminum for strength and durability. This space is designed as a direct replacement and requires no drilling or cutting. The spacer is completed in a red anodized finish for great looks in your engine bay. New gaskets and hardware are included for a quick and easy installation.

Emissions Legal
This throttle body spacer is 50 state legal for 2011-2014 Mustangs. Approval has not been set for 2015-2021 Mustang yet.

  • Fits 2011-2021 Mustang 5.0

    About This Brand

    Airaid - The Performance Intake Company
    AIRAID Premium cold air intake systems and air filters are constructed using the finest materials available today for your Ford Mustang. All AIRAID Premium filters utilize a urethane body that won’t crack or curl like their competitors’ rubber units. Filtration is second to none with the combination of AIRAID's proprietary SynthaFlow and multiple cotton gauze layers.

    All AIRAID Premium Filters are 100% reusable and feature a Lifetime Guarantee.

    AIRAID tests to SAE standard J726, the method for testing fractional efficiency of a filter. Each AIRAID® product line is the result of exhaustive research and development. Our in-house engineering team consists of both mechanical and industrial design engineers using the latest 3-D CAD modeling equipment to produce advanced designs that make more power right out of the box. A portable 3-D scanner and rapid prototyping machine allows AIRAID® to test new products on our in-house Superflow flow bench and verify the unmatched fit, finish, and style that AIRAID® customers demand. All products are then tested on our all-wheel-drive Mustang chassis dynamometer to produce real-world performance numbers.
