every one i know who has used the spray says that it does the job, myself i would rather remove the valve and clean/inspect as you can not tell if the valve is stuck in its operation while its on the car, instructions for the spray are as follows

# . Remove the flexible hose in the air intake system, situated between the turbocharger/intercooler and the air intake manifold. Start engine, run until it is warm

# Set engine to run at 2000 rpm.

# Spray the product, with short intervals, into the air intake manifold.after the maf sensor. IMPORTANT: If the revs increase when spraying the product, reduce revs from 2000 rpm to idle.

# RPM and diesel knocking can rise during pulverization.

# After each pulverization, wait until original set rpm is regained.

# Continue until the 200ml of product in the aerosol are consumed.

# Let the engine run at idle during a few minutes.

# Turn off engine

# Reattach hose

# Restart engine

# After this idling period, accelerate the engine approximately 5 to 10 times

# Do not exceed 3000 rpm.
