Mercedes A45 AMG 2.0L M133 Boost Leak Tester Kit (2013-2015) - Stock Turbo - Billet Aluminum

Get your boost back!  

This boost leak tester is designed to fit over the inlet flange of your turbocharger and allows you to pressurize the turbo and charge system with compressed air while the vehicle is off. 

The twin-scroll turbo on this motor has challenging task of spinning to make a whopping 27 PSI stock pressure! (1.8 bar) This translates to a very fast wheel speed and leaves little room for error.  A boost leak will dramatically increase the wheel speeds even more and put the turbo in a situation where it's constantly being overworked at full load, causing oiling issues, bearing wear and shaft play.  Once the shaft play becomes enough to cause the compressor and turbine blades to fluctuate enough to contact the housings, the turbo will fail catastrophically shooting pieces into the intake and exhaust. 

This is an important tool that every turbo car owner needs in their arsenal of tools.  It is going to keep the turbo healthy by eliminating leaks in the boost path and not allowing it to overspeed compensating for a boost leak.   It is a must if you are tuned and/or going to get a custom tune, or any time you are replacing any components in the intake tract such as charge hoses, intercooler, manifold, vacuum lines, injectors…etc.  Also a must if you are going to the track and want the peace of mind that the turbo isn't overworking and everything is tight and capable of handling sustained boost without any failures. 

Fits these Applications:
- 2013, 2014, 2015 Mercedes A45 AMG with stock turbo, W176 chassis code
- 2014 -2019 Mercedes A45 AMG with an upgraded Pure Turbos Stage 1 turbo
- M133 DE20 Engine:  

Benefits of the Boost Gauge on the Boost Leak Tester?

Not having a gauge readout on a boost leak test is similar to filling air in your car's tire without a gauge.  You just don't know how much air is in the system!   

It is very wise to know how much pressure is actually going into the charge system to prevent damage to your engine and to yourself - Example if the compressor is unregulated (using high pressure shop air at 90 PSI) there is a risk that the charge pipes will be over-pressurized and something will give - the boost leak tester could blow off or any component of the engine could.   

The gauge on the boost leak tester allows the user to:

1. apply a safe amount of pressure to prevent injury or damage to the charge pipes or engine
2. read how fast the system holds and bleeds air after removing the air source
3. give a good comparison of compressor outlet air Vs. boost test air while pressurizing.  The smaller the difference the lesser the air loss in the system

Design Features:

• Billet 6061 Aluminum End Cap with 1/8" NPT threaded gauge port & fitting port
• High quality branded silicone coupler
• Custom Stainless Steel 30 PSI / 2 Bar Boost Gauge.  30 PSI range will give you the appropriate reading when testing your charge pipes for low, medium or high boost levels.
• Universal Tire Schrader Valve (can be removed and tapped for 1/4" NPT thread fitting if desired)
• (2) Stainless Steel T-bolt Clamps with Teflon lock-nut
• Compact design to maneuver into tight spots.

Lifetime warranty on every component.
