Curious to know what you guys are doing as your aftermarket (or OEM) intercooler are starting to show their age. I've had my Active Autowerke intercooler install for close to 4 years now and removed the mesh infront of it to accentuate the BMW aero front lip. Now the intercooler is pretty gnarley --- caked in dirt, chipped/flaking paint from rocks etc. What have you guys done to combat this issue? Rattle can? Powdercoating?
I'm getting ready to drop the intercooler to re-do the piping and drain the coolant in the next few weeks so I'd like to hear some thoughts on restoring the intercooler to its original shine.
