The aFe Silver Bullet throttle body spacer for BMW M3 (E36) 1992–1999 features a serrated helix design machined from 6061-T6 billet aluminum to create controlled airflow turbulence before the intake manifold. That turbulence helps more complete combustion, improving throttle response, torque and peak horsepower by modest tested gains while eliminating whistle noise. Durable construction and a reusable design support long-term use.
