The aFe Silver Bullet throttle body spacer for 2014–2018 Mazda 3 (2.0L/2.5L) uses a serrated/helix entry to create controlled airflow turbulence just before the intake while eliminating the whistle common to other helix-only spacers. Machined from durable 6061-T6 billet aluminum, the spacer is intended to help the air/fuel charge burn more completely, improving throttle response and offering potential gains in horsepower, torque and fuel efficiency.
