You want to use the little vacuum line attached to the top of the throttle bodies that leads under the plastic cover in the middle of the intake.Get the engine warmed up and then remove the vacuum line at the throttle bodies and pop on a spare length of vacuum line to run into the sea foam can. Then with the engine idling, Slowly insert the length of hose into the sea foam can and try not to stall the engine to quickly. Get about 1/3 of the bottle sucked in and then quickly shut the car off and let it set for 5 minutes. Then start the car and enjoy the smoke show for the next 5-10 minutes.
The stuff has worked excellent on everthing I've tried it on and I recommend it.
