This harness kit has been designed for FA-series motors, specifically the 2013-2016 BRZ/FRS models, and the main purpose is to allow users to upgrade to the 2017+ ignition coils. The model year 2017+ ignition coils are known to be more reliable, with an improved design that seems to be more resistant to heat-related damage.
Set of four plug-and-play jumper harnesses.
Fits all 2013-2016 Subaru BRZ/Scion FR-S.
