Best Vaccuum Port?

Looking to do the Mopar Combustion Chamber Cleaner. Directions say to spray it into a Vaccuum port behind the throttle body but as close to it as possible. Anyone know if there is one? Where is it? Pics would be VERY helpful!

Idea is to have it run down all of the runners. Thanks for the help!
 
You may use the brake vacuum booster port. They use this port to clean the back of the intake valves and combustion chambers. You might want to do a search as there were some pictures shown. Ed
 
absolutely use the brake booster line.. that's the best for sure. it comes off the brake booster and to the back of the intake manifold.
