that's an interesting product.

that design is really similar to the oil cooler that the WRX uses. same exact idea.. a ring that goes between the block and the oil filter.. except instead of a gauge sender unit there are hardlines going to and from the rest of the cooling system, so coolant flows through and cools the oil as it goes through the filter

someone should retrofit that setup onto other cars.. it could be a cheap alternative to an aftermarket oil cooler
