You will need to lower them yourself. Most guys and the general rule of thumb is set all settings at 20 degrees lower than the factory settings.
I didn`t want my fans to run too often and living in Mn. is not like Florida so I set mine at 10-15 degrees cooler than the factory settings..........
Hope that helps.
Zoomer's install was a breeze! Quality parts for sure. I dilited some dishwashing liquid to lube up the hangers on the OEM and the new hangers which really helped them move. They sound great. I have a 6-speed, didnt notice any drone, driving normal, the interior noise was elevated but not un bearable. The only thing is the drivers side tip sticks out about 3/4" further than passenger side. Have to trim the coupling which should be an easy fix.
