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.

Good Enough
This doesn't fit precisely into place. You can see in the photo that the pleats just end with no frame on the sides to seal to the body of the housing. You can wiggle the end pleat into place but there's nothing holding it there so I don't know how long it will stay there. Not a big deal for me, but if you live on a dirt road, there could be enough air bypassing the filter that you may get a dusty car sooner. Price was fine, but I won't buy this filter again.

love it.
This filter fits a 2008 Lexus RX400h perfectly and gives the fresh, clean air. I recommend it.
