So I took off my AFM to lend to someone, and noticed the AFM, and the intake pipey thing that goes to the air filter is coated in an oily substance. I do have a HKS pod type filter, as it is the only thing that fit's under the the intake shieldy thing.
I haven't oiled the filter ever ( am I meant to ? ) but what damage if any could this oily substance do ?
The car is fine, no problems, just not sure if this oily substance should be there.
