This is the streamlined sport version of WOT's dual oil cooler kit, driver-side mounted with the same premium components in a single-core setup. The dual kit measured up to 35F lower oil temps and 30F lower coolant temps in testing; the single cooler is expected to deliver roughly half those gains, still ahead of any other oil cooling solution on the market for this platform.

Every component is genuinely premium: a PWR high-efficiency core, Raceflux 10AN oil lines with fiberglass and silicone insulation and a lifetime leak warranty, an HEL thermostatic sandwich plate with a 180F thermostat for proper oil warm-up, and a fender liner vent for real heat evacuation. The duct itself was CAD-modeled by Casale Design LLC, the same designer behind Spoon's Thill 24h bumper vents, not an amateur 3D print job.

Installation requires no cutting or bumper modification and is fully reversible, with radiator airflow, OEM brake function, and front-end grip all unaffected. Track testing showed only a 3-5 psi oil pressure drop versus OEM, with better end-of-session pressure than stock thanks to reduced oil thinning under sustained heat.
