Hybrid Racing presents a game-changing upgrade for your 8th Gen Civic Si - the Stage 1 intake system bundle, now enhanced with a ZDX J37 throttle body and all necessary components for optimal functionality. This bundle is the ultimate solution for those seeking to push their intake system to new heights.

Not Just Any Cold Air Intake

This intake system is a product of exhaustive design, testing, and refinement. The main body is crafted from ¼” thick fiberglass-reinforced silicone, balancing sturdiness with flexibility for easy installation without damaging surrounding components. Unlike metal or plastic, silicone provides superior insulation, leading to colder intake air temperatures (IATs) and, consequently, more power.

Performance gains with this system are significant, boasting a 14HP increase in peak power and a 9HP average gain across the rev range. When compared to similar aftermarket intakes, Hybrid Racing's system consistently delivers 2-3HP more, with smoother power delivery for better drivability. The 3.5” diameter tubing efficiently channels air from the fender well, making it suitable for a range of setups.

Space Optimization and Anti-hydrolock Bypass

The kit includes a cleverly designed tray to reposition the battery next to the transmission, creating space for the larger intake system and enhancing the engine bay's appearance. A silicone upper radiator hose is also provided for improved clearance.

Hydrolock prevention is a key consideration in wet conditions. The included air bypass manifold not only mounts the factory MAF and the provided silicone tube but also acts as a safety feature, allowing air to bypass the filter if it becomes saturated, as demonstrated in rigorous submersion tests.

Honda ZDX Throttle Body & Hybrid Racing Adapter

The bundle incorporates a Honda V6 J37 throttle body, offering a substantial size increase over the factory K20Z3 unit. This results in an additional 2-10HP gain on top of the intake system, with improved throttle response. The provided Hybrid Racing Adapter ensures a seamless fit, and the included thermal gaskets minimize heat transfer.

Complete With Hondata FlashPro for Perfect Tuning

To fully unlock the potential of this advanced intake system, tuning with Hondata’s FlashPro is essential. The FlashPro Manager software offers numerous calibrations to optimize performance for various modifications. It allows for comprehensive tuning and logging capabilities, ensuring your build evolves with your ambitions.
