This GT86 keeps things functional and driver-oriented. Perrin’s inlet hose and a K&N drop-in improve intake flow and filtration, while Mishimoto’s oil cooler and a Prosport oil pressure gauge show a focus on engine health under load. The Valenti fourth brake light is a clean aesthetic touch that integrates well with the roofline. It’s a restrained build that prioritizes reliability and monitoring — the kind of upgrades you do when you plan to push the car regularly and want the engine to stay happy while you do it.
