aFe Power Silver Bullet Throttle Body Spacer for Select 2008-2017 Honda and Acura Models (46-37001)

The aFe Power Silver Bullet Throttle Body Spacer is engineered to optimize the air-fuel charge for improved engine efficiency and performance. Fits select 2008-2017 Honda Accord, Civic Si, and Acura ILX and TSX models.

Precision-machined from T-6061 billet aluminum, this spacer features a unique serrated/helix entry design. This specific geometry creates turbulence in the airflow just before it enters the intake manifold, which helps the air-fuel mixture atomize more effectively. Unlike standard helix-only spacers that are prone to a high-pitched whistling sound, the Silver Bullet design is optimized to eliminate noise while increasing manifold volume for better throttle response and gains in horsepower and torque.
