Took off my front bumper to mock up my intercooler piping, put it back on and now the right turn signal is blinking fast. I've checked fuses, but don't know how to check the relays. Anyone else have this issue? I also tried the turn signal bulb from the other side, no difference. Shoot me some ideas/specific places to inspect

 

A wire is disconnected, check the wires to the bulb.

 

checked. Rapid flashing = more resistance if i recall, right?

 

They flash faster when there is a bulb out, or if you have the wrong one in.
Check your tail-light on that side also, and just make sure they're all Working even.
