Silicone Reducer Coupler – 3.5″ to 4″ (20° Bend) for 2018 Mustang Intake/Throttle Body

The 3.5″ to 4″ Silicone Reducer Coupler with a 20° bend is engineered specifically for adapting the 2018+ Ford Mustang GT intake manifold or throttle body to 3.5″ intake piping. The integrated angle provides improved alignment in engine bays where a straight coupler may not suffice, helping eliminate strain on components and improving airflow path efficiency.

Made from high-quality, multi-layer reinforced silicone, this coupler offers excellent durability, flexibility, and heat resistance. It’s ideal for both naturally aspirated and forced induction builds requiring precision fitment and OEM-level reliability.

Product Highlights:

Reducer Size: 3.5″ to 4″ transition
Bend Angle: 20° for improved fitment and alignment
Material: Multi-ply reinforced silicone construction
Temperature Resistant: Designed for high-heat engine bay environments
Pressure Rated: Capable of withstanding vacuum and boost conditions

Vehicle/Application Fitment:

Fits: 2018+ Ford Mustang GT intake manifold and throttle body
Compatible with 3.5″ intake tubing for custom setups
Perfect for cold air intake kits and manifold conversions

Installation Tips:

For best results, pair with quality T-bolt or worm gear clamps. Always check for proper clearance and hose alignment to prevent contact with moving engine components.
