Does your 912 run hot? Well, check out this ad on eBay for “Porsche 912 High Performance Engine Radiator Additive!”
According to the description of this “miracle” product (and boy, if it works, it sure is a miracle), it prevents overheating and pre-detonation (presumably by preventing your engine from starting after the first use), lubricates and seals (its death warrant), and … well, we aren’t quite sure how the gain in horsepower fits into all of this.
(For all those weened on Boxsters and 996s, all 912s were air/oil-cooled.)
