Introducing the 555 Engineering Dual Sensor Cooling Duct 🦆

If you’re pushing your car hard, heat soak at the manifold MAP/IAT sensor can influence false high Intake Air Temps (IAT)—forcing your ECU to pull power right when you need it most. On top of that, track-level heat wrecks high pressure fuel sensors (a hard lesson we learned firsthand on our GR Corolla Time Attack car 😅).

We engineered this duct to fix both issues in one move.

Why you need it:
❄️ 10–15°F Temp Drops: Channels fresh, ambient air directly from the bumper nostril inlet to keep both sensors cool.

🏎️ Endurance-Proven Pedigree: Modeled after thermal management tricks used by Toyota factory teams in Super Taikyu and the Nürburgring 24 Hour.

🔥 100% Engine Bay Proof: 3D printed in high-grade ASA polymer to survive extreme heat cycles, chemical exposure, and UV without warping.

⚡ Consistent Laps: Protects your fuel pressure sensor and keeps your ECU from pulling timing mid-session.

Available now at introductory pricing! Visit the 555 store to lock yours in before your next track day! 🏎️💨

GR Corolla AWD ITCC Cooler Motorsports Development

23/05/2026

Massive props to Chris Schuster and Lauren Judy from the team for securing a phenomenal 2nd Place finish last week in the Economy Class at the 2026 Tire Rack One Lap of America! 🏁

Their GR Corolla conquered a grueling 7-day, 3,500-mile marathon of endless highway transit, skid pads, and intense track sessions across middle America. When managing critical AWD temperatures mattered most under pressure, they relied on our 555 Transfer Case Cooler Kit. ❄️🏎️

555 Engineering Track Proven at Suzuka! 🇯🇵 🏎️

We recently had the privilege of track testing our full GRC Cooling Package at Japan’s F1 track, Suzuka Circuit. Coming to Japan has been a surreal experience for the 555 Engineering team. It’s one thing to build a kit; it’s another thing entirely to see it performing on a world-class F1 circuit like Suzuka.

We came to prove ourselves. 30-minute sessions at full tilt on one of the world’s most demanding tracks, and the Package didn’t miss a beat 🆒 👌🏼 .

But the best part? The Japanese GR Corolla Community. Hanging out with the local community and experiencing the passion and sense of family was absolutely the highlight of our trip.

We were humbled by the hospitality of our hosts and everyone else we had the privilege of meeting. We cannot thank you enough for having us 🙇.
