Skunk2 Composite Cold Air Intake System – 2012–2015 Honda Civic Si | K24Z7

Unlock proven horsepower and torque gains from your 9th Gen Civic Si with the Skunk2 Composite Cold Air Intake System. Developed in partnership with the championship-winning Compass360 Racing team and dyno-tested to deliver +6 whp and +8 lb-ft of torque on the K24Z7 engine, this is the best-performing and best-fitting cold air intake available for the 2012–2015 Honda Civic Si.

Unlike aluminum intake systems, Skunk2's molded polymer composite construction provides superior heat insulation — keeping intake air temperatures lower for denser, power-generating cold air to the engine.

Key Features

• Superior Thermal Barrier: Molded polymer composite construction provides better heat insulation than aluminum, resulting in lower intake air temperatures (IATs) and denser, cooler air to the K24Z7
• +6 whp / +8 lb-ft Torque: Dyno-proven gains on the K24Z7 — developed and validated with the Compass360 Racing championship team
• Optimized Airflow: Large 3.5-inch ID lower tube with a smooth continuous taper (3.5” to 3.0” ID) to the factory throttle body for unobstructed, high-velocity airflow
• Maximum Ground Clearance: Downward-facing filter design provides approximately 2 inches of extra ground clearance vs. competitors, reducing water ingestion risk without cutting fender liners
• Retains OEM Battery: Unique bracket design allows the factory battery to remain in place — no battery relocation required, simplifying installation
• Complete Kit: Includes composite tubing, high-flow air filter, silicone connector, and all necessary hardware for a precise, bolt-on fit
