2015 STi turbo tmic coupler kit
By Robert May 6, 2018Got this kit to replace the stock tmic coupler and the turbo to tmic inlet coupler and the GrimmSpeed coupler did NOT fit you have to cut the coupler up and basically guess. I matched it up to the stock size one. After install the turbo to tmic was still to big causing it to bend behind the intercooler and restricting boost. In the end I pulled the GrimmSpeed off and returned to stock coupler, I would not reccomand this product for tmic.
