Throttle Body Inlet Spacer for Ford Focus (2013-2018) RS ST 2.0 & 2.3 Ecoboost Engine

R-Spec Throttle Body Spacer Kit for Ford Focus ST & RS MK3 (2.0L / 2.3L EcoBoost)

Enhance throttle response and unlock sharper performance from your MK3 Ford Focus ST or RS with this precision-engineered throttle body spacer kit. Designed specifically for the 2.0L and 2.3L EcoBoost engines, this spacer improves airflow as it enters the intake manifold, helping your engine respond quicker while delivering smoother boost and improved efficiency.

By optimizing the airflow path, this throttle body spacer allows air to move more evenly into the manifold, resulting in crisper throttle response and a more connected driving feel. Whether you’re daily driving or pushing the car harder, the difference is noticeable when you step on the accelerator.

Built for enthusiasts who want both performance and flexibility, this kit includes dual 1/8 NPT ports that allow easy integration of accessories such as boost gauges or water/methanol injection systems. The ports come pre-fitted with blanking plugs, so you can install the spacer as-is or customize it later without modification.

Precision CNC-machined from billet 6061 aluminum, the spacer offers excellent strength, durability, and resistance to heat. The anodized black finish not only protects against corrosion but also provides a clean, understated look in the engine bay. A high-quality O-ring seal ensures an airtight connection, while the included high-tensile bolts provide a secure and reliable installation.
