BMW E82 / E88 1-Series come from the factory with an auxiliary radiator smaller than a half sheet of paper. It will do little to keep the "limp mode" or heat soak away during a track day.

The Dinan High Capacity Oil Cooler provides literally twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that's really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiency and the ventilation of air to the fender well has also been improved with a larger outlet. The system mounts neatly in the stock location and includes lightweight convoluted PTFE hoses with polyester outer braid fitted with race-quality fittings.

The results of the oil cooler upgrade are quite significant, with the temperature gauge holding steady even under high load/high boost scenarios. And for those of you who track their cars, even occasionally, the Dinan oil cooler is a must.

Finally Found a Magnesium That Works Without Side Effects
Size: 180 Count (Pack of 1)
I started taking this magnesium because I was dealing with frequent leg cramps, especially at night, and it has made a huge difference for me. Since using this brand consistently, my cramps have almost completely disappeared and my muscles feel much more relaxed. Another thing I really appreciate is that it does not upset my stomach or cause diarrhea like other magnesium supplements I tried before. After testing several brands, this is the only one that has worked well for me without uncomfortable side effects.

Works great!

Purchased this item at the recommendation of my PCP to help alleviate my Charlie Horses in my legs. Take 3 tabs an hour or so before bedtime, and it solved that issue.

It's easy to take one pill a day.

I sometimes get cramps in my calves while sleeping, so I eat before bed. Personally, I think it's effective. I am satisfied with the product and delivery.
