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.

The one bone to rule them all
This bone is definitely the favorite of all the different rubber bones we’ve tried. In fact, we did a green rubber bone test of two we bought to replace an old one and it was a clear winner. I don’t think it’s a matter of the sqeaky getting damaged as some dogs may eventually puncture the bone itself and then it won’t squeak. My little goober has serious teeth and she cannot stop squeaking this one. Also it bounces and I can throw it pretty far.
