Part Number: PRL.1077.1.0

Description: PRL Cobra Intake

Fitment: 22+ Honda Civic SI 1.5T

Details:

This system is a direct-fit, no-tune-required cold air intake engineered for reliable gains, clean sound, and consistent real-world performance.

This is not a short ram setup. The Cobra Intake routes air from the driver-side bumper duct, isolating it from the heat of the engine bay to reduce IATs and improve combustion efficiency. The system includes our precision CNC-machined billet MAF housing, a rotomolded HDPE lower tube, and multi-layer silicone couplers for smooth airflow and long-term durability. The standard bore MAF maintains factory fueling behavior, eliminating the need for a tune.

Dyno testing on a stock Civic Si showed up to +16 HP and +9 lb-ft of torque, with improvements visible across much of the rev range. This intake also deletes the factory cold-side resonator, and includes a rubber plug to cleanly block the opening.

We’ve built this system with 304 stainless steel brackets and clamps, and our proprietary high-flow oiled filter is included. Every part was designed with consistency, reliability, and OEM-like fitment in mind.
