Product Description

The K&N 63 Series AirCharger is a cold air intake for the 2016-2021 Honda Civic 2.0L with the naturally aspirated K20C2 engine. It replaces the factory intake tube and filter with a black roto-molded intake tube, an oversized reusable filter, and a vehicle-specific heat shield.

The 63-3517 gives the tenth-generation 2.0L Civic a more direct intake path while keeping the installation tidy under the hood. K&N estimates gains of 3.12 horsepower at 44 MPH and 3.9 lb-ft of torque. For most owners, the more noticeable change will be improved induction sound and a sharper response when the engine is worked through the rev range.

The included High-Flow Air Filter uses oiled cotton-gauze media that can be washed and reused instead of discarded. Its oversized conical shape is designed for long service intervals, making this a practical 10th Gen Civic intake for owners who want a reusable filter and a complete heat-shielded setup.
