CTS Turbo A90/91 Toyota Supra & BMW G20/G21/G29/G42 Series Transmission Oil Cooler
Hard driving cooks the factory transmission cooler on the A90/A91 Supra and BMW G20/G21/G29/G42 cars — once it overheats, shifts go sluggish. The CTS Turbo transmission oil cooler is a dual-core design nearly 2.5x larger than the OEM unit, so it holds shift performance even under sustained abuse. It is the ideal upgrade for road racing and drag duty.
