UPR Products Pro Series Silicone Coupler; 3.50-Inch; Black (Universal; Some Adaptation May Be Required)

Multi-Ply Mastery Built to Survive the Heat of Battle. The UPR Products Pro Series Silicone Coupler is constructed using advanced multi-ply reinforced silicone, a material proven in motorsports and aerospace for its exceptional strength-to-flexibility ratio. Unlike conventional rubber hoses that break down under heat or exposure to fuel vapors, this coupler delivers lasting performance even in engine bays approaching—or exceeding—400°F.

Designed to Endure the Furnace Beneath Your Hood. Under sustained boost, during hot-lap sessions, or in bumper-to-bumper city traffic, temperatures can skyrocket. That’s why the UPR Products Pro Series Silicone Coupler is engineered to tolerate extreme thermal loads without softening, bubbling, or becoming brittle over time.

Lock in Your Boost, Unlock True Power. Power leaks are performance killers. The UPR Products Pro Series Silicone Coupler is precision-molded to deliver airtight fitment at every junction, safeguarding against pressure loss during wide-open throttle pulls, peak turbo spools, and rapid gear transitions.

Airflow-Optimized for Throttle Response That Snaps. Beneath its rugged exterior, the UPR Products Pro Series Silicone Coupler is engineered with a smooth, polished inner surface that enhances laminar airflow through your intake system. This aerodynamic interior reduces air friction and turbulence—delivering faster response, more precise MAF sensor readings, and better throttle modulation under both cruising and hard-boost conditions.

Flexibility Where It Counts, Strength Where It Matters. In the crowded confines of today’s engine bays—especially those with aftermarket charge pipes, big turbos, or relocated components—fitment is everything. The UPR Products Pro Series Silicone Coupler offers enough flexibility to snake into tight junctions and imperfect angles without sacrificing integrity.
