I like this one the best since it's actually intelligent. Something to keep in mind, assuming he still has a top mount, the only people who see the stencil are those who he wants to see the stencil. On your front mount, everyone will get a look.

 

Painting the FMIC is a bad idea because you might want to take it back to stock someday and you don't want to buy a stock fmic because the original has paint residue on it. I agree with man-law. Retaliation is necessary. I think you should retalliate with vinyl though. That way you can make your point, then take it off whenever you don't feel like you want it anymore. Also, you can be more creative with your come-back.

 

This is just a bad idea in general. Maybe it's for kicks, maybe it's for an intercooler you can swap out at leisure, but it's still somewhat lame to put in that much effort.

How about, do nothing and just be faster than him? I mean, you do own an Evo, and thats the cherry on top in my book compared to an STi...

At any rate, you can get paint off of an intercooler. It's called HVAC condenser coil cleaner. That's what it's made for. To get anything off of air conditioning condenser coils.

 

STiNK is funny but how can you write that on your car? People will think you smell bad.
