Cobb 2016-2018 Ford Focus RS Hard Pipe Kit

Upgrade your 2016–2018 Ford Focus RS with the COBB Hard Pipe Kit, a high-performance solution designed to improve airflow and boost response by replacing the restrictive factory plastic charge piping. This kit delivers increased durability, a cleaner engine bay appearance, and optimized flow for both stock and upgraded intercoolers.

The 2.5” mandrel-bent aluminum piping eliminates bottlenecks found in the OEM system. Both the hot and cold side pipes are constructed from single-piece aluminum tubing—completely weld-free—resulting in smoother internal surfaces and fewer potential failure points.

Finished in a sleek wrinkle black powder coat, the piping resists corrosion while enhancing under-hood aesthetics. Heavy-duty 4-ply black silicone couplers provide a tight, secure seal, and T-bolt hose clamps are included to prevent boost leaks under high pressure.

The COBB Hard Pipe Kit is fully compatible with the factory intercooler as well as most OE-replacement upgraded intercoolers, making it an excellent foundational mod whether you’re staying stock or planning for more power.
