Improves Low-End Torque and Responsiveness If you want to squeeze every last ounce of performance out of your 3.5L EcoBoost means getting down to the nitty-gritty of your Explorer's intake system, and the aFe Silver Bullet Throttle Body Spacer can help you do that by making the airflow going into your 3.5L EcoBoost's intake manifold more efficient. The spacer installs between your Explorer's throttle body and intake manifold and works by smoothing out inbound airflow into a helix pattern, which allows for increased air pressure in your engine's cylinders, which adds some low-end torque to your quick SUV's output. The spacer is a quick, simple upgrade that helps you get more out of your Explorer Sport.
Quality Billet Aluminum Construction Each one of aFe's Silver Bullet Throttle Body Spacers for the 2012-2017 Explorer Sports is designed for a quick, drop-in replacement for stock with exceptional quality. The spacer is manufactured out of CNC machined 6061-T6 billet aluminum with a natural satin finish. The spacers comes standard with an OE-style O-ring for sealing against the throttle body and easily bolts into place behind it without a ton of hassles.
