Durable Cts Turbo A90/91 Toyota Supra Bmw G-series Z4 30i/m40i/m340i B58/b48 Heat Exchanger (cts-a90-hx) Save 80% Now [y4MlqCzu]

CTS Turbo is proud to announce our Front Mount Heat Exchanger for the Toyota Supra A90/91 and BMW G-series B48/B58 platform. The factory front-mounted heat exchanger is small and not efficient enough to provide enough cooling to tuned B48/B58 engines. We designed our heat exchange to overcome that problem. The double-pass core was made to be higher flowing and larger than the factory but still drop into the stock location. CNC machined mounting points and hose connections allow for a seamless install without any need to cut or trim any factory parts. Keep your B48/B58 running cool and reliably with CTS Turbo Front Mount Heat Exchanger. Features:

  • CNC machined mounting points and hose connection for factory fitment
  • Drop-in design
  • Smooth bends on the coolant connections
  • High-efficiency double-pass aluminum core
  • Hand-welded and pressure tested
  • Lowers intake air temperature
  • Installation hardware included
  • Fully compatible with factory rock guard, simply transfer the factory parts over
  • Replaces OE#: 16400-WAA03 and 17118666811
Vehicle Fitment (2.0T and 3.0T engines):
  • 2020+ Toyota Supra (A90/A91) B48/B58
  • 2018+ BMW G29 Z4 20i, 30i & M40i
  • 2018+ BMW G20 3-Series B48/B58 (320i, 330i, 330iX, M340i, M340iX)
  • 2018+ G21 3-Series Touring (330i, 330iX, M340iX)
