Billet Aluminum Serrated Helix Airflow Spacer

The aFe Power Silver Bullet Throttle Body Spacer is precision machined from 6061-T6 billet aluminum, providing a balance of light weight, high strength, and a refined finish. Its innovative serrated/helix design intentionally creates turbulence within the intake air, promoting a more complete and efficient combustion cycle. This results in noticeable gains in horsepower and torque, along with improved throttle response. Dyno-proven results show gains of up to +12 HP and +14 Lbs. x Ft. of torque. The spacer also helps to slightly lengthen the intake tract, further increasing intake air speed and contributing to the performance enhancements. Compatibility with OE and aFe POWER cold air intake systems is noted, though some aFe POWER systems will require modification of the intake tube. Specifically, this throttle body spacer will fit with aFe POWER air intake systems 51-12172, 54-12172, 51-12162, and 54-12162, but will require intake tube modification. However, it will NOT fit with aFe Power air intake systems 51-72203, 54-72203, 51-72203-R, 54-72202, 51-72202, 58-10003D, 58-10003R, 54-12162-C, 51-12162-C, 54-12172-C, or 51-12172-C.
