This M177 Auxiliary Heat Exchanger Kit with carbon fiber air baffle upgrades the low-temperature cooling circuit on the 4.0L BiTurbo V8. It significantly reduces heat soak, lowers intake air temperatures, and delivers more consistent power under high load and hot conditions.

Key Features & Benefits

  • Upgraded Auxiliary Heat Exchanger — Larger core provides significantly better heat rejection in the low-temperature circuit
  • Carbon Fiber Air Baffle — Directs high-pressure cool outside air into the exchanger core, the critical piece most kits miss
  • Reduced Heat Soak — Maintains lower and more stable intake air temperatures during aggressive driving and track use
  • Faster Temperature Recovery — Cools down quicker between hard runs and in traffic
  • Bolt-on Solution — Uses factory mounting points and quick-connect fittings for straightforward installation

Frequently Asked Questions

Is this a full intercooler upgrade?

No — it upgrades the auxiliary low-temperature circuit that cools the main intercoolers.

Why include the carbon fiber baffle?

It directs cool outside air into the auxiliary core — the missing piece that makes the upgrade truly effective.

Will this require tuning?

No tuning is required. It works on stock and tuned vehicles.

How noticeable is the difference?

Most noticeable in hot weather, repeated hard runs, and on the track.
