I planned to remove it, but ended up re-fitting / running the OEM set-up. I've still got a Mocal thermostatic sandwich plate and oil cooler in the garage... I'll probably fit over winter, if needed.
I would run both of them. The water-oil will heat up the oil quicker, and the dedicated air-oil cooler will keep the oil cool Sent from my LG-H870 using Tapatalk
