I have a 4 series gran coupe with the sport line package and I want to swap to the front m sport bumper. I was about to pull the trigger for a bumper kit from Kies motorsports until it said 200 in shipping. I found someone selling an oem front m sport bumper that comes with the vent grills. Will that fit? Or is there something else I need

You'll need all the parts that go behind the front OEM m sport bumper. You cannot mount an OEM m sport bumper over sportline hardware. Please note that should also swap the side skirts and rear bumper to m sport for everything to match. The steering wheel is also different along with all the window trim. It's a very expensive retrofit. I recently completed it on my 435i.

I have already done the steering wheel on my car and I already know what comes on the m sport package I am just wondering about the bumper, I wanted to know if I could just buy this that comes with the grills and everything or if I should just buy a conversion kit from an aftermarket company

If you stick with the OEM grill you'll need to the ducting that goes behind it with all the small mounting hardware.

And not all MSports are the same. Some have additional cooling, some do not. Your front bumper, with fog lights, came off a car that did NOT have additional cooling. Further, I think early MSports came with the track pack which included these coolers, while the later MSports had the track pack as an additional option. i came across this assumption this week when a 16 435i MSport came into the bay in my shop. The differences were staggering between it, and my 14 435iMS

Not necessarily. My car has both the fogs and the aux radiators on both sides.
