Thank you!

Thanks for the video.
You removed the heat-exchanger which cools the ACC. Has its own separate coolant system.
I see another huge Radiator, 2 more radiators on the sides? That’s for the engine.
Then there’s the oil cooler mounted face down. For the engine.

Just got this in the mail. How much coolant should I expect to need to add after the install? Thank you.

[@mishimoto]

The increase in capacity is 0.6 gallons

@@mishimoto Thank you !

[@BEAR_S55]

With this installed will the VRSF front facing air filters still fit as this is larger than the oem exchanger?

[@mishimoto]

Unfortunately, we do not test our products with those of our competitors. Sorry!

[@kevinryan2556]

What should I do with the old coolant fluid?

[@mishimoto]

We would suggest recycling based on your local laws.

Torque specs?

[@mishimoto]

OEM torque specs are in play here. Otherwise, as long as everything is slightly over "snug", you shouldn't have any problems.
