Introducing the Mishimoto 2021+ BMW G8X M2/M3/M4 performance heat exchanger, the ultimate solution to keep your charge air cool under the most demanding conditions. In the world of forced induction vehicles, air-to-water intercooling is the future, and Mishimoto are taking it to the next level.----We started from scratch, leaving no room for compromise. Our design eliminates all plastic components, replacing them with durable aluminum end tanks, core, and CNC-machined ports. TIG-welded for maximum strength and longevity, this heat exchanger will withstand even the harshest conditions. We took it further by incorporating strutted tubes within the core, adding unparalleled resistance against bowing and flexing during aggressive cornering.----But strength is not our only focus. We've increased the core volume by 23 percent and expanded the external fin surface area by 44 percent. Combined with our dual-pass flow configuration and louvered fin design, this performance heat exchanger vastly improves cooling capacity over stock, enhancing overall performance.----Rest assured, the Mishimoto Performance Heat Exchanger for the 2021+ BMW G8X M2/M3/M4 is designed to fit perfectly with all other factory components, ensuring seamless integration into your vehicle. For added protection, we include steel rock guards to shield the heat exchanger from debris and prevent punctured tubes or crushed fins. The Mishimoto G8X M2/M3/M4 performance heat exchanger fits both automatic and manual transmissions.----The Mishimoto 2021+ BMW G8X M2/M3/M4 performance heat exchanger comes with our renowned Mishimoto Lifetime Warranty, giving you peace of mind and confidence in your investment.

Really snug, but not uncomfortable
Size: Large, Color: Black
I don't know why these were so much tighter than all the other UA socks I've bought over the years. Not uncomfortable, just really tight when putting them on.

Leg part is TIGHT
Size: X-Large, Color: Black
I am a size 15, and the foot portion is comfortable enough, but the fit of the leg portion is so exceedingly tight that I can't wear them for long, which makes them worthless. I would return them if I didn't already toss the packaging.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast. These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid. A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day. We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice. Ratings: • No slipping: 10/10 • Price: 7/10 • Durability (so far): No pilling or loose threads — promising start.
