Seafoam
 

WHat vacuum hose should I use to Seafoam my '95 Cobra?

I would try and find a small one right after the throttle body. You gotta watch how much you let it suck in at a time because it could choke down the motor also.

Yeah I watched a video on it and it told me to use one third of the can and go slowly but it told me to use the brake booster hose and my brake booster hose goes to a splitter for three hoses and I want a more direct route because the splitter is plastic

And it also told me to go slowly or I could stall my engine. So I will keep that in mind but thanks though, I'm gonna look for a hose attached after my throttle body tomorrow

If you go from a small hose right after the TB it should follow the natural airflow of the intake. Booster hose is towards the back of the intake and may only spray to a couple cylinders and definitely won't cover the entire thing.
