Hello I am just looking into getting back into a Focus. Do they have a MAF sensor? If the intake doesn't change the MAF and uses the stock one I would think it wouldn't affect things too much.

Unless from the factory the car is extremely leaned out already to get the best MPG it can. Then it might be risky.

I know on my Evo they are really rich from the factory so an intake leaning them out a little is no big deal. The problem with those is when you buy an intake that changes the MAF. Then it reeks havoc on the ecu.
