Conical Filter, Road Spray, Fenderwell Liner

[FordNut]

The title says it all.

I drove about 200 miles in the rain today with my new airbox (at least the bottom half) and Pro-M MAF/conical filter. Got back to the shop and took it back apart for some more finish work on the carbon fiber (it was mainly put on for test fit and showing at breakfast). Found grit and sand in the bottom of the airbox. The only place I can figure it came from is the road spray from the left front tire. Gotta close up that hole in the fenderwell now for sure! Thinking about cutting up an old fenderwell liner from a car I parted out awhile back and trimming it to fit the front part of the fenderwell.

I haven't inspected mine yet, but one plus for the PHP kit is that it does have an entirely closed box (excluding the front) while many others only have a big exposed conical filter.

Brian...keep in mind that there is another "access" for moisture/sand & dirt in the area of the airbox. On the underside of the hood, directly over the radiator cowl/cover...there are 2 holes on each side. I'm assuming as some sort of vents. Sometimes when I open my hood...I've got little piles of sand/dirt that look like ant hills on the cowl. One is located directly above the airbox.

Just wanted to say it could be coming from above, as well.

I'll be able to close up the fenderwell a lot easier and faster than making the carbon fiber top cover for my airbox, so we'll find out one step at a time!

I really believe it is coming in from the two holes in the radiator support panel, but I could be wrong (again!). If my wife ever heard me say that I would have to eat a whole truckload of crow.

Well, as you have successfully blazed so many trails before for all of us Brian...keep us up to date with whether the fenderwell blockage does the trick.

Oh, and I said 200 miles in the rain... I actually drove from Knoxville to near Tallahassee, then back to Atlanta. Used 2 tanks of gas. Mostly drove 85, sometimes a little more spirited, other times slowed for traffic, at least 95% on highway. Got 19.8 mpg on one tank and 20.2 on another. Quite pleased with that.

After installing my 9" K&N and "Precharger" wrap, I drove about 150 miles through NJ & PA in the rain. I stopped every so often to check on it because I was worried about water and road grit. To my suprise, the Precharger wrap wicked away ALL of the water and moisture prior to it coming in contact with the filter itself. The wrap also deflected all grime and dirt... nothing sticks to it. K&N says that the wrap allows about 98% of the air flow through like normal. I'd gladly give up the 2% to ensure that my filter stays cleaner and the air charge is not obstructed. Check out the K&N site for more info. They list sizes for the wrap on there... you might find one to fit over your ProM filter.

be careful how much you close up. You could create a scenario for overheating.
