Compatible with BMW M140i, M240i, 340i, 440i (B58 Gen 1)

Unlock reliable performance from your tuned or track-driven B58-powered BMW with do88’s upgraded Front Intercooler Water Cooler. Designed as a direct-fit replacement for the factory heat exchanger, this TIG-welded all-aluminium unit massively increases cooling capacity to combat heat soak — a known issue on B58 cars under prolonged load.


Why Upgrade?

Heat Soak – A Common Limiting Factor on Tuned B58 Engines

Just like the S55 in the F80 M3/M4, the B58 uses a water-to-air intercooler system — but with the intercooler integrated into the intake manifold. Unfortunately, this makes the system prone to heat soak, especially when tuned or driven hard. When intake temperatures rise, the ECU will reduce ignition timing or enter limp mode to protect the engine.


do88’s Cooling Solution

The do88 Front Intercooler Water Cooler dramatically increases the system’s ability to shed heat, allowing your B58 to maintain consistent performance during spirited road driving or track sessions.

A sweater is the ultimate clothing item for staying warm and cozy. Whether it's a chilly winter day or a cool summer evening, a sweater is there to provide comfort and protection. Its soft and knitted fabric feels gentle against the skin, making it a pleasure to wear. One of the greatest advantages of a sweater is its versatility. It can be dressed up or down, depending on the occasion. Pair it with jeans for a casual look, or wear it over a dress for a more elegant ensemble. With so many colors, patterns, and styles to choose from, there's a sweater for every taste and preference. Not only does a sweater keep you warm, but it also adds a touch of style to your outfit. From chunky cable-knit sweaters to sleek and form-fitting designs, there's a wide range of options to suit any fashion sense. Sweaters can be accessorized with scarves, hats, and jewelry to create a unique and personalized look. Another benefit of a sweater is its durability. Well-made sweaters are built to last, making them a wise investment in your wardrobe. With proper care, a sweater can withstand years of wear and still maintain its shape and quality. In addition to its practicality and style, a sweater also holds sentimental value. It can remind us of cherished memories, like cozy evenings by the fireplace or family gatherings during the holidays. Wearing a favorite sweater can evoke feelings of comfort, nostalgia, and a sense of belonging. In conclusion, a sweater is the optimal choice for both fashion and function.

Will buy more
Size: X-Large, Color: Black Pullover
This sweatshirt is a great basic that works for everyone. The fit is comfortable and true to size, but also looks good a little oversized if you prefer a looser style. The material is soft on the inside and warm without being too heavy. It’s perfect for men, women, and teens — super easy to layer or wear on its own. The quality is better than expected for a generic sweatshirt, and it’s held up really well after multiple washes with no shrinking or fading. Simple, cozy, and a great everyday sweatshirt for all sizes and genders!

Comfortable Everyday Hoodie
Size: Large, Color: Black Pullover
This hoodie is a great basic to have on hand. The fleece material is soft and comfortable, and it provides just the right amount of warmth for cooler mornings and evenings. The fit was true to size, and it held up well after washing without losing its shape. My husband likes wearing it for everyday errands, walks, and casual outings. It's comfortable, lightweight enough to layer, and easy to throw on when you need an extra layer. A solid, affordable hoodie for everyday wear.
