I bought some seafoam spray today?

I know some people don't like seafoam and that's fine. All I want to know is how to use the spray on my 2001 Honda Civic. So I guess what I'm asking is where is my air intake? Please let me know As soon as possible.

I think you want to pour it into the brake vacuum line, run the car and then put it in the oil. Do some research on the topic or go to the seafoam web site for instructions.
Also, If you put it in the oil, you only want to run the car a few minutes, and I would not rev the engine like on the video, but just get the RPM up and slowly move it up and down a few times.
Then I would change the oil and filter.

If something is wrong with your car, don't expect Seafoam to magically fix it.

One of the headaches of Seafoam is it doesn't spray, it just pours. If you do the brake line thing instead of a small hose, be sure to go very slowly. Seafoam is notorious for bending connecting rods in Hondas, ruining the engine. I don't know why the death rate for Hondas is so much higher than other makes unless it is because it is too easy to feed it too fast.
