Maximize your 2022+ Honda Civic Si with a Performance Intercooler Kit engineered to deliver more power and keep intake air temperatures low during demanding drives. Built with cast aluminum end tanks, a robust bar-and-plate core and high-flow aluminum piping, this complete kit provides gains of up to 8.1 horsepower and 8.1 lb-ft of torque over stock. The piping replaces restrictive factory pipes with a hot-side design that increases flow area by 103% and a cold-side that adds 75%, while removing the OEM resonator to deliver a sharper, more aggressive induction sound under boost. With a 146% increase in core volume and rated for builds up to 572 HP, this kit keeps your 1.5T running strong whether you're pushing hard on back roads or logging lap after lap at the track.
Average outlet temperatures drop by 18.1°F compared to stock, helping your engine maintain consistent power and preventing heat soak during hard driving. The welded aluminum construction and cast end tanks provide the durability needed to handle rigorous driving, while the optimized piping is paired with wire-reinforced, 5-layer DuraCore™ silicone couplers capable of handling extreme heat and boost pressure. The cold-side pipe includes a pre-drilled 1/8" NPT sensor port for auxiliary sensors or gauges, giving you the flexibility to monitor performance as your build evolves.
Installation is plug-and-play with a complete kit that includes all necessary couplers and hardware. High-quality worm gear clamps ensure secure fitment and quick installation, making it easy to upgrade now and revert to stock later if needed. Backed by the Mishimoto Lifetime Warranty, this kit combines durable construction, proven performance, and hassle-free installation for Civic Si owners ready to push their builds further.
