how does a man test his intakes boots using the "spray" test

hi guys

I've seen a couple listing about this but wonder what type of spray you use and how it works ??

thanks

I believe you must use some sort of combustible aerosol. Carb & choke cleaner, or starter should work.

While the engine is idling, spray the aerosol near the intake boots. If the boots have a good seal, nothing should happen. If the RPM's change that means you have a leak. Either the boots are not properly seated or they are compromised.

While cupping his jewels? 

I'm joking of course, he'd probably do it the same way a woman would.
