Short Ram Intake for Honda Civic (2016-2021) 2.0L

High-Flow Short Ram Intake Adapter for 2016-2021 Honda Civic

Engineered to optimize intake velocity and mass airflow sensor readings, this adapter connects standard 3-inch ID conical filters to factory or PRL Motorsport intake tubes.

The Stock Civic Bottleneck

The factory intake system on the 10th-generation Civic is heavily restricted by baffled resonator boxes and a standard panel filter designed primarily for NVH reduction rather than volumetric efficiency. This restrictive OEM airbox induces parasitic pumping losses as the K20C2 engine attempts to draw in adequate ambient air under heavy throttle loads. Furthermore, the standard plastic enclosure is highly susceptible to heat soak in the tightly packed engine bay, causing elevated intake air temperatures (IATs). This forces the ECU to retard ignition timing, directly suppressing low-end torque and overall throttle response.

The Engineering Solution

This precision-designed short ram adapter eliminates the restrictive factory airbox, allowing the installation of a high-flow 3-inch internal diameter conical air filter directly to the OEM or PRL Motorsport intake tube. Manufactured in the USA, the unit is constructed from high-density black ASA (Acrylonitrile Styrene Acrylate) plastic. ASA provides exceptional thermal stability to resist engine bay heat deformation, outstanding mechanical rigidity for a secure, leak-free MAF sensor seal, and excellent chemical resistance. The denser material composition ensures precise MAF scaling without turbulence-induced errors, unlocking improved induction acoustics and throttle sharpness. (Note: Requires a separate 3" ID air filter).

Common Questions

Will this short ram intake adapter fit my 2016-2021 Honda Civic 2.0L?
Yes, it is built for 2016-2021 10th-generation Honda Civic models equipped with the naturally aspirated 2.0L K20C2 engine (FC2 sedan and FC4 coupe).

Does this adapter fit turbo Civic models or the Civic Type R?
This listing is made specifically for the naturally aspirated 2.0L K20C2 engine and connects to the factory 2.0L intake tube or PRL Motorsport Stage 1 intake tube.

Is a cone air filter included with this part?
This package includes the high-density black ASA plastic short ram intake adapter, and it requires a separate 3-inch internal diameter (ID) conical air filter to complete the setup.

Which intake tubes work with this adapter?
It connects directly to your OEM factory intake tube or a PRL Motorsport Stage 1 intake tube, replacing the stock resonator airbox.

What material is the adapter made from?
It is manufactured in the USA from high-density black ASA (Acrylonitrile Styrene Acrylate) plastic for high thermal stability against engine bay heat and a rigid, leak-free MAF sensor seal.
