Description
The COBB Redline Carbon Fiber Turbo Inlets are a premium airflow and durability upgrade for Gen3 Ford F-150, F-150 Raptor, and F-150 Tremor models equipped with the 3.5L EcoBoost engine. Designed and manufactured by COBB Tuning, these turbo inlets replace the restrictive and failure-prone factory plastic inlet tubes with high-strength carbon fiber components.
Factory turbo inlet tubes on the 3.5L EcoBoost are known to neck down, restrict airflow, and become brittle over time due to repeated heat cycles. The COBB Redline Turbo Inlets eliminate these issues by providing a smoother, less restrictive airflow path while significantly improving long-term reliability.
Each kit includes two carbon fiber turbo inlet tubes, one for each side of the engine. The tubes are constructed using a 2x2 twill carbon fiber weave with a gloss finish for maximum strength, reduced heat soak, and a clean under-hood appearance. The system uses black 5-ply reinforced silicone couplers throughout, secured with high-quality clamps to ensure a leak-free seal under boost.
This kit is fully compatible with factory turbochargers and installs as a direct replacement without requiring tuning. For vehicles equipped with Garrett PowerMax turbocharger upgrades, an alternate COBB coupler kit is available separately to maintain proper fitment and airflow.
The COBB Redline Carbon Fiber Turbo Inlets are 50-state legal and approved for use on emissions-controlled vehicles when installed according to the manufacturer’s application guide.
