STP® Professional Series Diesel EGR Cleaner Cleans air intake system inlet valves and EGR valves

STP® Professional Diesel EGR Cleaner is designed to quickly dissolve gum, lacquer, carbon and tar like deposits from the air intake system.

Directions

Start the engine and allow it to warm up.
Remove the flexible hose that is located between the turbo charger or intercooler, and the air intake manifold. Continue to run the engine on idle.
Shake can thoroughly before use. Spray the product for 2 seconds into the air intake manifold but DO NOT SPRAY DIRECTLY INTO THE INTERCOOLER.
After each spray, wait until the idle rpm is restored and engine runs stable. Repeat the process until all of the product has been discharged from the aerosol.
In extreme cases, dismantle the EGR valve housing and spray the product liberally and directly onto the unit. Allow to soak for a few minutes and repeat until contaminants are removed. Wipe away excess with a soft clean cloth.
