My car has a perrin FMIC, but honestly there’s quite a few people on IWSTI and nasioc running the SSAC intercoolers and they have great luck with them. I just can’t bring myself to chance it I stick with what is known to work.
If you wanted to even to a minor intercooler upgrade the 08+ TMIC’s were a good bit larger and flow a bit better. I’m sure it would help with your power up top.
