Even the stock LT4 has heat management challenges. Start adding boost, throw on a larger supercharger, and before long your IATs are running 150°F or higher — killing power and putting stress on your engine. Speed Engineering's large capacity heat exchanger gives your C7 Z06 the cooling capacity it needs to keep IATs in check. Featuring a 2.25" core, direct bolt-in fit using factory mounting locations, and full compatibility with your existing OEM plumbing and fittings — no modifications required.
Note: No instructions are included with this heat exchanger.

Frequently Asked Questions:
Q: Why do I need a heat exchanger upgrade on my C7 Z06? The LT4's supercharger relies on a liquid-to-air intercooling system using a heat exchanger to cool the charge air. Even in stock form the factory unit can struggle to keep IATs in check, especially during repeated hard pulls or in warmer conditions. Modified applications — more boost, larger superchargers, hotter climates — push the stock unit even further. This upgrade provides a 2.25" core for meaningfully improved heat dissipation.
Q: Does this heat exchanger use factory mounting locations and plumbing? Yes. This heat exchanger bolts directly into the factory mounting locations and is compatible with all OEM plumbing and fittings. No custom lines or brackets are required.
Q: Do instructions come with this heat exchanger? No. Instructions are not included. Familiarity with the C7 Z06 LT4 intercooler system is recommended before installation.
Q: What vehicles is this heat exchanger compatible with? This heat exchanger fits the 2015–2019 Chevrolet C7 Corvette Z06 with the LT4 6.2L supercharged engine.
Q: What is the difference between this heat exchanger and the ZL1/CTS-V kit (27-1001)? Part 27-1003 is a direct replacement heat exchanger for the 2015–2019 C7 Corvette Z06 LT4. Part 27-1001 is an upgrade kit designed for the 2017–2019 Camaro ZL1 and 2016–2019 Cadillac CTS-V LT4 applications. Both address the same IAT issue on the LT4 supercharged engine but are specific to their respective vehicle platforms.
