Seafoam
like Techron or any other valve cleaner or additive should only be used
every 10-15k miles. Over the course of normal driving carbon
deposits itself on the back of the valves and piston tops.
Using a cleaner through the intake can help control these
deposits, which can cause a loss in fuel economy and performance.
Below you can see two pistons removed from an engine with
30,000 miles. The piston on the left is from a cylinder
treated with Seafoam.

Start
by
measuring out 6oz of Seafoam into a small glass jar. Now,
with the car heated up and running locate a vacuum line that can be
disconnected at idle, or source one from the vacuum tree under the
throttle body cover or off the wastegate. Place your finger
over the line to confirm it is indeed a source for vacuum that feeds
into all the intake runners. Leave your finger over the hose
until you are ready to begin.
Slowly submerge the vacuum line in the Seafoam until the engine starts
to stumble. This step is a balancing act of keeping the
engine idling while tying to induce the cleaning solution as quickly as
possible. If you are having a problem with the engine
stalling, try dabbing the vacuum line in and out of the solution.
Once you have introduced the 6oz of seam foam shut then engine off and
wait 10 minutes.
Once ten minutes have elapsed and you have reconnected the vacuum line
re-start the engine. At this point the exhaust will smoke and
you may experience some back firing. This step is the Seafoam
burning off. Wait until the smoke has slowed and then take
the car on a 2-3 mile drive. During acceleration expect some
light to heavy smoke which will subside after a few mile.
This valve cleaning process should be repeated every 2-3 oil changes.
