Putting this up for sale for a friend of mine who recently sold his M2 Comp.

Want to get 75-100bhp and 100Nm from your F8x M2/M3/M4?

This is a smart way to get it without interfering with your OEM ECU. This is in more than your cheapo tuning box. It also has a remote Bluetooth control so you can revert to stock at the click of a button.

Steinbauer are a well recognised brand in the world of tuning. In fact they are the brains behind some of the AC Schnitzer tuning kits that you can buy directly from the BMW Dealer network.

This was in the car for less than a year and was fitted & removed by the authorised agent here in Cork. I drove the car with it and it transformed the car.

It can be fitted at extra cost along with a before and after dyno test.






€650 (nearly half price)
