Can Cleaning Intercooler Increase Power | Evo X

Cleaning the IC of my 12 year old (at the time, I am uploading this 1y later) Evo X.
For these 12 years, quite a lot of oil was gathered, the intake pipe before the turbo was also quite oily.
About the tests, After 1 year, the tems are around IAT + 13-14 in where IAT is around 35C when tested, so
still quite good and better than the IAT + 17/18 I was getting before that.

So yes, cleaning the IC is benefitial.
Also, make sure you add catch can and not re-connect the PCV valves back in the system.
