K&N 12-13 Honda Civic 1.8L L4 Silver Typhoon Intake

If you're looking to get a bit more out of your 2012-2015 Honda Civic with the 1.8L engine, this K&N Typhoon cold air intake system is a solid option. It's designed to replace your restrictive factory air box and intake tubing with a smoother, more direct path for air to enter your engine. This improved airflow is what helps your engine breathe better, potentially leading to a noticeable increase in both horsepower and torque.

The K&N Typhoon system features a mandrel-bent aluminum intake tube, which means the tube maintains a consistent diameter throughout its bends, allowing air to flow more freely. It comes with K&N's washable and reusable High-Flow Air Filter, which uses oiled cotton gauze to capture dirt while letting plenty of air through. The oversized, conical shape of the filter is key to its performance and allows for extended service intervals, often up to 100,000 miles between cleanings under normal highway driving. A custom heat shield is included to help block hot air from the engine bay from getting into the intake, ensuring cooler, denser air enters the engine for better combustion.

Installation is typically straightforward and can often be completed in under 90 minutes, usually without needing any specialized tools beyond what most DIYers have on hand. K&N backs this intake with their Million Mile Limited Warranty, giving you confidence in its durability.
