Billet Aluminum Throttle Body Spacer

The Steeda 555-3225 is a billet aluminum throttle body spacer, manufactured in-house for the 2011 and later Mustang GT models equipped with the 5.0L 4V Ti-VCT V8 Coyote modular engine. Some sources suggest gains of 2-4 horsepower, with anecdotal evidence of up to a 4 MPG boost, though it's important to note that throttle body spacers are sometimes debated for their effectiveness on modern engines. Installation is straightforward and typically takes only a few minutes. Importantly, a tune is generally not required after installing this throttle body spacer. This specific model (555-3225) is designed for the 2011+ Mustang GT. It's worth noting that a different Steeda throttle body spacer (555-3106) is designed for the 2005-2010 GT Mustang and does NOT fit with the 2010 stock engine cover.
