AutoLine Pro 3.5" (89mm) Premium BoostCap Turbo Boost Leak Tester - 6061 Billet Aluminumst Cap - 30 PSI Gauge - Detects Intercooler, Charge Pipe & Intake Leaks

• Restore Lost Power, MPG & Turbo Engine Health: Hidden boost leaks silently rob your turbocharged engine of horsepower, fuel economy and long-term durability, even with no audible hissing. Regular use of this turbo boost leak tester catches invisible pressure leaks before they cause sluggish throttle response, poor MPG or costly turbo damage on factory-turbocharged vehicles - making it the most proactive boost leak detector you can keep in your garage.
• Fast, Accurate Pressurized Leak Detection: Attach this boost pressure tester securely to any 3.5" O.D. turbo inlet or hard intake pipe, then test boost integrity across the entire charge system with shop air (engine off) to instantly pinpoint leaks at intercooler end tanks, silicone couplers, clamps, BOV/DV, throttle body flanges and more
• Eliminate P0299 Underboost & Related Fault Codes: Pressure leaks destabilize turbo spool speed and skew air-fuel ratios, triggering P0299, P0171, P0174, P0172, P0175, and other boost-related codes. Sealing leaks restores proper AFR balance and resolves trouble codes for smooth, reliable engine operation.
• Aerospace Grade 6061 Billet Aluminum Cap Construction: This aluminum universal turbo boost cap is precision-machined and hard anodized for lifetime corrosion resistance anti-slip retention beads and circumferential grooves grip hoses firmly under pressure for an airtight seal every test. No plastic parts, no compromise on quality, and no degradation from heat or shop chemicals over time.
• Dual-Fit Stepped Aluminum Cap Adapter: As an added bonus, the stepped aluminum cap also slides into flexible silicone boot hoses, giving you broader compatibility.
• 30 PSI Liquid Filled Shockproof Pressure Gauge: The built-in turbo boost gauge features glycerin-fill that dampens needle flutter for stable, accurate readings. This precision boost gauge is rated to 30 PSI (2 Bar), well above the 15-20 PSI operating range of most stock and lightly modified turbocharged platforms, giving you confident, precise diagnostics.
• Complete Ready to Use Kit Everything Included: Comes with the billet aluminum BoostCap tester, 30 PSI liquid-filled gauge, universal Schrader valve (compatible with standard tire air chucks tire inflators), compressor quick-connect fitting, and heavy-duty stainless steel T-bolt clamps. Unbox and start testing immediately, no additional purchases needed.
• Ideal for Professional Shops & DIY Mechanics Alike: Whether you're a professional technician diagnosing a customer's underboost complaint or a home mechanic chasing a boost leak, the AutoLine Pro BoostCap delivers shop-grade accuracy in a durable, portable design that stores easily in any toolbox.
• 5 Year 100% Full Coverage Warranty: The most confidently warranted turbo boost leak tester in its class.
