I built the snorkel after that trip. I hit the water way too hard and soaked the air filter and MAF. Fortunately I was able to dry the sensor and drive, carefully, without the air filter. I will attach some pics of the snorkel. It is made primarily from shop vac parts. I am doing a little test to see if I have lost any power or gas mileage due to the small diameter tubing I used. I dont feel any power loss but I can easily remove the front of the air cleaner to disconnect the snorkel.
looks great especially for vac parts... but u sure may wanna clean ur engine bay some time..haha
i dont think that you would have lost any gas milage... if u have then just get a scoop on the top .. something like this that will increase airflow
