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 heat exchanger upgrade kit gives your cooling system the extra capacity it needs to keep IATs in check. Featuring over 150% more volume than the factory heat exchanger, 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 kit.

Frequently Asked Questions:
Q: Why do I need a heat exchanger upgrade on my LT4? 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 in warmer conditions or with repeated hard pulls. Modified applications — larger superchargers, more boost, hotter climates — make the stock unit even more inadequate. This upgrade provides over 150% more volume for dramatically improved heat dissipation.
Q: Does this kit use factory mounting locations and plumbing? Yes. This kit 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 kit? No. Instructions are not included. Familiarity with the LT4 intercooler system is recommended before installation.
Q: What vehicles is this kit compatible with? This kit fits the 2017–2019 Chevrolet Camaro ZL1 and 2016–2019 Cadillac CTS-V with the LT4 6.2L supercharged engine.
