Just run the risk. Doesn't necessarily void it, but when you're stock, and something breaks, the warranty covers it with no gray area. If you have a CAI or tune or S/C or whatever that has now modified how the engine performs, Ford could blame the problem on the modifications, which would put your friend on the hook for the cost of repairs.
