Mishimoto 15-20 BMW F8X M3/M4 Performance Air-to-Water Intercooler Power Pack - Black SapphireAvailable in 12 BMW specific colors, your go fast parts in the engine bay can now match the exterior beauty of your F8X. The beauty is more than just skin deep too. Our improved core design features a bar and plate core with a 29% increase in core volume, as well as a unique single pass coolant flow layout for optimal heat transfer. Combined with our 16% increase in flow through the core we were able to record a 12F temperature drop in intake air
Available in 12 BMW-specific colors, your go-fast parts in the engine bay can now match the exterior beauty of your F8X. The beauty is more than just skin deep too. Our improved core design features a bar-and-plate core with a 29% increase in core volume, as well as a unique single-pass coolant flow layout for optimal heat transfer. Combined with our 16% increase in flow through the core we were able to record a 12°F temperature drop in intake air temperatures while testing our full Power Pack. An air-to-water intercooling system wouldn’t be complete without the heat exchanger. When it came to BMW’s design, it was a solid foundation, but we still saw room to grow, literally. Our full aluminum design added 6" to the height of the core equating in a 180% increase in external fin surface area, and a 60% increase in core volume. With our heat exchanger in the S55’s system we recorded a 10°F drop in global intercooler coolant temperatures, and an average gain of 11 whp and 8 wtq when the full Mishimoto 2015-2020 BMW F8X Performance Intercooler Power Pack was tested on our stage 1 tuned M3. For added security, we made sure to include our optional steel mesh stone guard with the Mishimoto Performance Heat exchanger to keep all of the tubes and fins intact. We also utilized a variable fin pitch on our heat exchanger’s core for optimal cooling on DCT equipped vehicles. Where the F8X generation of the M3, M4 and M2 Competition were designed to pull ahead of the rest, there were still somethings that were left to be desired in terms on intercooling. The Mishimoto 2015-2020 BMW F8X M3/M4 Performance Intercooler Power Pack is the perfect companion for your build, and like all of our products, is covered under the Mishimoto Lifetime Warranty.This Part Fits:

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days.
Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.
