Mishimoto 2021+ BMW G8X M3/M4 Transmission CoolerThe ZF 8 speed transmission found in the 2021+ BMW G8X M2 M3 M4 is a stout and snappy unit that's capable of withstanding the onslaught of torque brought on by the S58 engine it's mated to. Add a tune and some bolt ons, and the stock cooler just can't keep the ZF 8HP safe. This inadequacy can lead to high transmission oil temperatures, sluggish shifting, and potential transmission damage. Fortunately, the engineers at Mishimoto have developed a

Fit perfectly, but questionably thin.
Style: CA11053A
This was an exact fit for my 2017 Kia Forte S. My only convern is that it is half the width of the stock filters. Hopefully the different material will make the difference over time. Didn't notice a loss or gain of torque or acceleration after swapping for my old dirty filter.

Increased MPG!
Style: 33-3131
I don't know if it increases power, but it for sure has an increase of 1-2 MPG. About the same MPG increase as a K&N, but half the price.

Time will tell
Style: CA11053A
As another reviewer pointed out, the OEM paper filter is almost 3 times thicker than this one. All things equal, thicker would mean for filtering surface area. So with less filter media surface area, the filter would clog up quicker. However, since this is washable, maybe that's a moot point. I also noticed on my Hyundai Tucson, the rim of this filter must be slighter thicker because I had a tougher time clipping the filter box closed with this one installed. I am keeping my OEM for now, just in case.
