1.5T Turbo Inlet Pipe

The 27WON Turbo Inlet Pipe is the largest diameter inlet pipe available for the 1.5T powered Civic and Integra, measuring 80mm. This one-piece design replaces the restrictive factory component, aiming to enhance airflow to the turbocharger. It is crafted from A356-T6 aluminum, known for its high strength and light weight, and is available in a natural uncoated finish for custom color matching or a classic textured black powdercoat for a stealthy look. It is intended to work well as a standalone upgrade but truly shines when paired with other performance modifications like a turbo upgrade or Front Mount Intercooler (FMIC). Initial testing with supporting mods and 91 OCT fuel showed average gains of 6 WHP and 4 WTQ, with a peak gain of 11 WHP. With an optimized tune, gains of nearly 26 WHP and 15 WTQ were observed across the entire RPM range. 27WON guarantees a direct drop-in fit with no tune required and no check engine light (CEL). The design also addresses the factory EVAP nozzle by relocating it to the back with OEM-style fittings for a cleaner appearance. The product comes with a Limited Lifetime Warranty and is designed and machined in Vancouver, WA. This Turbo Inlet Pipe is compatible with various intake systems, including the OEM Honda Airbox, the 27WON Short Ram Intake (SRI), and the 27WON Hybrid Cold Air Intake (CAI). A specific 4-ply TIP coupler is included for the PRL HVI Intake System. The product is designed for all 2022+ 1.5T Honda Civic Si and Non-Si trims, as well as all 2023-2025 1.5T Acura Integra trims, and works with both 6-speed manual and CVT transmissions.
