Drewkaree, that brings up another question. Where do our boats draw their air from? What is the path it has to travel to make it to the engine compartment and what we can do to improve it.
Fresh air circulates into the engine compartment through vents under the back rest on the swim platform.

Anyone tried directing this air more directly into the intake to help get cooler. cleaner, denser air into the engine?

A couple members have routed the CAI to the back of the engine compartment over the fresh air intake.

The stock box looks pretty restrictive so I thought it was worth a shot. Still don’t regret it though because it opened up a ton of space in the engine compartment and also makes it much easier to reach the oil filter. It’s crazy how much space the stock air filter takes up.

Waste of money if you ask me. I've done lots of dyno tests and CAIs are usually worth nothing and many times worse than stock. Adding an exposed snorkel to pull high pressure air won't even make a noticable difference on a boat.
