Improve the cooling capacity on your 2015-2020 BMW M3 or M4 with the Mishimoto Performance Heat Exchanger. Air-to-water intercooling is the means of more efficient heat transfer from the charged air, but it now requires an additional heat exchanger mounted to the front of the vehicle in order to dissipate the transferred heat. The S55 powering the F8X generation of the M?s packs quite a punch and while the BMW engineers laid a solid foundation for dissipating the heat from the intercooling system, but we saw some room to improve. We started by eliminating any bits of plastic from the design, and replacing the end tanks, and ports with durable aluminum. We kept the dual-pass flow through the core for maximum cooling properties, while expanding the core into the available space. Our new design features a 42mm thick core while extending the height by 150mm totaling in a 60-percent increase in core volume and adding 180-percent to the external fin surface area. The end result of our improvements is a 9 F drop in global intercooling system temperatures over the stock unit. Size isn?t the only thing that matters with this heat exchanger. Since the heat exchanger sits front and center in the M3 and M4?s cooling stack, It's susceptible to damage from road debris. To keep your air-to-water system safe, our heat exchanger comes equipped with a steel mesh stone guard for an added layer of protection for the fins. We also incorporated a variable fin pitch for the lower 12 rows on the core in order to facilitate cooling to DCT equipped M?s. Finally, our 2015-2020 BMW F8X M3/M4 Performance Heat Exchanger also includes the Mishimoto Lifetime Warranty for a worry-free install.This Part Fits:

Worth it! Get it
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
I was pleasantly surprised at the quality of this shower curtain liner, especially for the price. We have bad water; turns other liners a pinky orange color. This has not turned colors, thick material. And I love how it has magnets to keep it attached to the tub to avoid water getting out onto the floor

Liner Filled with Lots of Light
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
Basic liner with the added magnets so you are not constantly having to put your curtain where it needs to go to prevent water from your shower escaping and ruining your floor.
Does exactly as it is intended and is clear so light is allowed into your shower where you can finally see things and not have to guess.
Packaged folded and neatly into a plastic and thick wrapper and all you need to do is open, unfold and install with ease. It fit perfectly into the hooks and the length and width of my shower as the description accurately states. When the time comes for that monthly cleaning, just un-attach and throw into your washing machine and then air-dry and it’s brand new once more.
