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.

Exactly what I was looking for.
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Although other reviews found this item was too lightweight and flimsy, frankly it was exactly what I was looking for. I needed to partition my workspace off from the rest of the room and I wanted something that I could easily attach to the back of an unfinished bookcase as part of creating a private space. It was perfect. Lightweight easy to handle and I didn't mind putting some nails through it. Great price point for what I needed.

Made cheaply.
Color: White, Size: 3 Panel
Seems fairly sturdy ( 3 panel white) but made with extremely cheap materials that will not last. The cheap materials are very noticeable with the white screen. No assembly needed. Would not but again.

Beautiful brown privacy screen!
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Why did you pick this product vs others?: The measurements were perfect for what I was looking for.  The length and width are the same as my rattan raised garden bed which I have placed in front of the screen on the deck.  This secures the screen so there is no issue of weather conditions. I have been looking for weeks for a privacy screen at every possible product and combination. and almost gave up when I noticed the measurements of the screen would fit behind my raised bed!  Now I am going to plant some flowers in it.  This is a terrific buy for me.  i am so happy! Looks great: The perfect size, color, and design match my brown deck rattan furniture. Ease of assembly: No assembly which is nice in this hot weather! Room divider: It provides much needed privacy

Good coverage and size, looks nice and easy to use.
Color: Black, Size: 6 Panel
My son uses this to partially cover his window as he is in a high rise and people can look in. It is tall enough and wide enough to provide reasonable coverage and because it doesn't require putting it together, it is very handy to use immediately. Good value for the dollar and looks nice.
