Hey guys, we just traded in our 2003 EB Excursion 7.3l 4x4 for a brand new 2011 King Ranch EL Expedition 4x4.

I have a few questions:

1.) I'd like to upgrade the headlights to HID. I know that the factory bulb is an H13, but I can't find any information on whether it is a dual filament or not. I don't see a separate bulb in the housing for a high beam. Which kit do I need?

2.) I live off of a dirt road that sometimes requires the use of 4 wheel drive and I'm interested in lifting the truck and going with either 33" or 35" Goodyear Wrangler Kevler MT/R tires. Is there a lift kit out there that won't void my factory warranty?

3.) Will larger tires function with the tire pressure monitoring system?
