Torque Solution TS-BLT-4 4" Turbo Inlet Boost Leak Tester Adapter

Vehicle Fitment

• Universal fit - for turbocharged systems with a 4.0" (≈102 mm) turbo inlet diameter. Use across multiple makes and models.

Features

• CNC-machined 6061-T6 billet aluminum body provides high strength and durability
• Black anodized finish with Torque Solution branding for a professional look
• Includes high-quality 5-layer silicone coupler and heavy-duty T-bolt clamps to secure the adapter and prevent leaks
• Integrated tire-valve style stem port allows compressed-air pressurisation of the intake system for testing
• Allows trap-and-trace of boost leaks: attach the adapter to the turbo inlet, pressurise, listen or use soapy-water to locate leaks
• Helps identify leaks that reduce performance or increase turbocharger workload and risk of failure
• Precision engineered to maintain proper inlet geometry and avoid distortion during testing
• Backed by limited lifetime warranty offered by the manufacturer

Product Description

The Torque Solution TS-BLT-4 Boost Leak Tester is designed for use in high-performance turbocharged systems to accurately diagnose intake and intercooler system leaks before they compromise power or cause turbocharger problems. Fitting directly to a 4" turbo inlet, the tester uses pressurised air and the included coupler/clamp hardware to isolate the system and allow you to listen for escaping air or apply soapy-water to exposed joints to visually identify leaks.

By catching leaks early, you can prevent power loss, boost creep or erratic turbo behaviour. The billet aluminium construction and quality coupler/hardware ensure minimal distortion under pressure, preserving the integrity of your inlet geometry while testing. Because this is a universal tool rather than a vehicle-specific kit, it can be used across multiple turbo setups regardless of the vehicle make or model.

This tester is ideal for performance tuners, shop technicians, or DIY enthusiasts working with turbo systems who want to verify system integrity. Use it whenever you install or tune a turbo, upgrade the intercooler piping or troubleshoot suspected intake leaks. Please ensure you use safe pressure levels and appropriate safety procedures when pressurising any intake system.
