Did my first oil change on my new 2011 WRX today and was a little disappointed to find there's no oil-to-water heat exchanger on this engine. I know they're not that effective but still, too bad.

Anyone know when this started? I thought they used to have them, but was it only on the STi engines or maybe only on the EJ20s?

you're making me think... I'll have to look at my 06 wrx to see if it has one.
