Upgrade your turbo system with a high-performance inlet engineered for durability, efficiency, and style. The Killer B Motorsport Turbo Inlet is designed and made in the USA using heat-treated, precision cast aluminum—offering a significant reliability improvement over the failure-prone OEM plastic version.

Unlike silicone inlets that can collapse under pressure or high heat, this cast aluminum design maintains structural integrity, ensuring consistent airflow with no pressure drop. The long, swoopy bends are optimized to reduce turbulence, increase flow capacity, and enhance turbocharger acoustics—delivering that signature turbo sound that turns heads and adds instant street credibility.

This inlet is easy to install and compatible with both OEM and 3" compressor inlets. It includes all necessary vacuum fittings to support OEM and aftermarket setups, and best of all, it does not require intake manifold removal for installation. A durable black powder coat finish adds both protection and a stealthy appearance under the hood.
