Infiniti QX80 Throttle Body Spacer - aFe - Silver Bullet, Serrated/Helix - `14-`24. This precision-machined throttle body spacer fits 2014–2024 QX80 V8 5.6L applications and is designed to improve intake airflow and throttle response with minimal modification.

The Silver Bullet Serrated/Helix design produces controlled air turbulence in the intake manifold to raise intake pressure and improve cylinder filling. Machined from 6061-T6 billet aluminum for strength and low weight, the spacer installs using factory mounting locations and includes gaskets and a silicone coupler to allow for thermal expansion and engine movement. aFe reports measurable gains in throttle response and performance; the manufacturer lists up to 6 HP and 8 ft-lbs of torque as a reported increase. This design also reduces intake whistle commonly found with helix-only spacers (US PAT 07055513).

Features

• Serrated/Helix pattern for optimized airflow and reduced intake whistle
• 6061-T6 billet aluminum construction for durability and light weight
• Includes gaskets and silicone coupler for expansion and vibration isolation
• Uses all factory mounting points for straightforward installation
