Vibrant 4 Ply Reinforced Silicone Transition Connector - 2.5in I.D. x 3.25in I.D. x 3in long (BLACK) - Universal
Vibrant Performance Aramid Reinforced Silicone Couplers provide durable connections for custom air intake and intercooler systems on turbocharged and supercharged vehicles. This 2.5 inch to 3.25 inch inside diameter x 3 inch long black transition hose fits performance imports like Subaru WRX STI and Mitsubishi Lancer Evolution as well as domestic muscle cars with aftermarket boost setups. Hand-wrapped 4-ply construction resists swelling and bursting under heavy pressure while meeting SAE J20 standards.
Key Features
- 4-Ply Aramid Reinforcement: Hand-wrapped layers endure high boost pressures and prevent collapse or failure in demanding conditions.
- Extreme Temperature Rating: Operates reliably from -65°F to 350°F for cold starts and track heat.
- SAE J20 Compliant: Passes industry tests for quality ensuring consistent performance in coolant and air applications.
- UV and Ozone Resistant: Maintains flexibility and strength outdoors or under hood exposure over time.
- Transition Sizing: Seamless connection between 2.5in and 3.25in pipes ideal for throttle body to intercooler or MAF to turbo piping.
Product Notes
- Suitable for air intake and coolant use only not oil or fuel contact.
- Inspect for cracks after high-heat runs and replace as needed.
- Arrives rolled in protective packaging to avoid creases or damage.
Installation Notes
- Professional installation recommended.
- Use T-bolt clamps rated for at least 50 psi sized 2.75in to 3.5in wide.
