Everyone with oil temp issues

They would have had to engineer brackets and fittings and sheaths and whatnot to try to bring the reliability up to par with the rest of the car, and done extensive long-term-wear simulation, etc. I have no idea how to work out what that costs in the long term in a car price. Let's say it ended up being $1000 or $1500 (not unreasonable, considering they're selling an unwarrantied and less-engineered addon cooler for $700).

Car prices are cutthroat these days, and a grand here or there on the mfg side of things isn't chump change. This is before all the percentages for various markups and taxes too.

The oil:water interface in the block is enough for most people on the streets, the cooler is the track upgrade. I agree that this isn't ideal (especially for the enthusiasts), which I've commented on before, but I can definitely see their financial angle on this. What percentage of 370Z owners do you think will ever even have (much less notice) a brief oil temp spike over 260? We're not the norm.
