are you talking about the trans cooler fittings on the radiator? The engine is going to produce more heat taxing the small radiator, i dont think you want to add engine oil heat into that mix. generaly the engine oil should be fine without a cooler unless your turbo and autocross the car at which point expense shouldnt be spared and a proper oil cooler should be run

And the 1999-2000 Civic SI EM1 never came in an automatic transmission.

But, Honda uses the same radiator, with a couple fittings for the automatic versions of other trim levels. Even if it were not originally installed, somewhere along the way it could have been.

Just get a proper oil cooler. They're not that expensive and you'll get better cooling. On that note, get a new dual core radiator also. They're like $40 on eBay.

honda does not use the same radiator for the em1 si as other trim levels. inlet/outlet is bigger on a b series.
