00 SD intake restriction.

Anybody ran in the rain with this setup yet? Does the air filter get water-logged?

Yes, for 2 years now. Plowing through a river...yes. Normal driving....no. Remember the oil in the filter will "repel" most errant moisture. An oiled filter cannot become water logged if it's oil logged.

Oil may repel some moisture, but didn't Ford change the air intake from the left front wheel well to the front of the engine (for the '99.5 model). Also Ford issued a TSB on it for "snow" clogging the air inlet, but a lot of customers were getting their air filter soaked with water, and it caused stalling and low power.

Just another comment on air restriction. I installed the K@N Filter Charger on my Y2k F250 Super Duty 4x4 V-10 5 speed 3.73. At the same time I cut a nice opening in the black plastic grille shroud and screened it. Not going to sit here and claim gains, but must reiterate that cooler air creates horsepower!!! Also for what its worth I did same scenario with my ol' 91 F250 and went 9 years in one of the snowiest places in the lower 48 without any snow or moisture problems on the K&N Filter. By the way my mileage unloaded averages 14.3 on the highway. Do drive with a Vaccumm Guage and that makes a big difference.

Check my intake modification at

I did this in conjunction with a catback system and I noticed a performance difference.

Back to the original question - Has anyone cut the plastic behind the grill to let more air in? I did. I used a drill with a hole-saw to cut a really nice round hole. Right after making the cut, I too wondered if rain would get in and make my filter wet. I don't know...I guess I'll drive it in the rain and see. I'm thinking it will get really wet though. I thought about adding a "diverter" of sorts to keep the airflow, but move the water. I don't notice any increase in power so my recommendation is to not cut the hole.
