Honda uses the oil "heat exchanger" as a way to warm the oil when the motor is cold. As a cooler, it doesn't really do a whole lot. If you want lower oil temps, run an aftermarket oil cooler that will see sufficient air flow.

It shouldn't matter, it'd be no different than running your oil relocation kit. It didn't utilize the oil cooler.
The only concern I would have is the fact that it is so close to the turbo manifold. Maybe a small heat shield would help?? Or maybe just get some of the stick on heat stuff and put it on your filter and keep some spare for oil changes?? haha
I agree a small heat sheild or heat tape would do just fine.

Are you sure about this? Because the oil will warm up way before the coolant so this wouldnt be true and would mean its meant to help keep the oil temps at bay.
This worked well - my clearances are tight and the filter never gets hot.
As your picture shows yo uare running a top mount manifold/turbo setup. I believe the op is discussing a bottom mount application making this considerably more dangerous to the oil filter.
I recommend removing the oil filter and warmer/cooler. You can buy a new spigot to mount an adaptor from Honda for a few bucks. Then relocate your filter and use an aftermarket air/oil cooler.
There is so much room at the front of the car and so little down beside the engine that this just makes good sense.

oil deff. doesn't warm up before the coolant does. you can tell by looking at the pressure of the oil if you don't have an oil temp gauge.
The heat exchanger does help a tiny bit when oil temps get way up there, but it's not like you're cooling the oil with cool coolant.

I dont understand this because when the engine is cold and is started, the oil is already being pumped throughout the engine and warming up from friction while the coolant is stagnant or not flowing for about 2-3 minutes until the temp is brought up to where the thermostat opens. If the coolant is stagnant or not flowing through the oil cooler/heat exchanger until the thermostat opens, how is it getting warmed? The only way I could see that the coolant is getting warmed would be from the engine block warming up and also the oil being warm and flowing through the oil cooler/heat exchanger. Wouldnt this mean that the oil will be warmed before the coolant is?
