COBB 7F4360 Redline Carbon Fiber Turbo Inlets | 2021-2026 Ford Raptor F-150 & 3.5L EcoBoost F-150

Overview

The COBB Tuning Redline Carbon Fiber Turbo Inlets (Part #7F4360) are a premium, performance-focused upgrade engineered specifically for the 2021–2026 Ford F-150 and F-150 Raptor equipped with the 3.5L EcoBoost twin-turbo engine. Designed to directly replace the factory plastic inlet tubes — which are known to crack, degrade, and restrict airflow after repeated heat cycles — these Redline inlets deliver a notable airflow increase while eliminating a critical failure point in your truck's intake system. Built for F-150 and Raptor owners who demand both show-quality aesthetics and real-world performance gains, the COBB 7F4360 turbo inlets are the definitive bolt-on upgrade for the Gen3 EcoBoost platform.

Key Features & Benefits

• Premium 2x2 Twill Carbon Fiber Construction — Each tube is hand-laid using a 2x2 twill weave pattern with a stunning gloss finish, delivering a bespoke Redline-series aesthetic that stands out in any engine bay.
• Eliminates a Factory Failure Point — The OEM plastic turbo inlet tubes are prone to becoming brittle and cracking over time due to repeated heat cycles. COBB's carbon fiber construction is vastly more durable and heat-resistant, providing long-term reliability.
• Notable Airflow Increase Over Stock — The factory inlet tubes neck down significantly, creating an airflow restriction. The COBB Redline inlets open up the inlet path to both turbos, supporting increased power output, especially when paired with a COBB Accessport tune.
• 5-Ply Reinforced Silicone Couplers — Heavy-duty 5-ply silicone couplers are used throughout the kit, providing a secure, airtight, and vibration-resistant connection at every junction — far superior to brittle factory plastic couplings.
• Dual-Tube Kit — One for Each Turbo — The complete set includes two carbon fiber inlet tubes, one for each side of the 3.5L EcoBoost's twin-turbo setup, ensuring a balanced and symmetrical airflow upgrade to both turbos.
• Factory Turbo Compatible Out of the Box — Couplers are sized and designed to work directly with the factory Ford turbochargers for a true bolt-on installation. An alternate coupler kit is available for trucks upgraded to Garrett PowerMax turbochargers.
• 50-State Legal / CARB Compliant — This product holds California Air Resources Board (CARB) Executive Order numbers D-660-274 and D-660-296, making it legal for sale and use on emissions-controlled vehicles in all 50 states.
• COBB Redline Series Quality — Part of COBB's top-tier Redline product line, featuring premium carbon fiber complemented by bespoke black anodized or E-coated hardware and the iconic COBB Redline badge.
• Accessport & Stage Package Compatible — These inlets are compatible with the COBB Accessport V3 and COBB's Off-The-Shelf (OTS) Stage Power Package maps, making them a natural foundation for a comprehensive F-150 performance build.
