DC Sports Cold Air Intake (17-20 Honda Civic Si) Read reviews

Built around the Si-specific MAF diameter, this aluminum tubing intake ditches the factory airbox bottleneck so you get sharper throttle response, quicker turbo spool, and a deeper induction sound every time you roll into boost. You’ll feel it right away, especially in the midrange where the stock setup falls on its face.

Why You’ll Want This on Your Si

•  Cold air OR short-ram in minutes – The two-piece mandrel-bent aluminum intake pipe drops the high-flow intake filter where Civic Si owners want, behind the bumper for true cold air intake gains. Daily a lot of rain or snow? Pop off the lower section and run it as a fender-well short-ram without redoing your whole setup.
•  Si-calibrated airflow – A CNC-machined MAF housing matches the factory sensor curve, so you avoid the lean spikes and weird trims you see with “one-size-fits-all” intakes. Your ECU stays happy, and you get an intake upgrade that doesn’t demand a tune right away.
•  Washable performance air filter – The oversized, oiled cotton Civic Si performance air filter flows up to 40% better than stock. It’s fully washable and reusable, so you’re not buying throwaway filters for the life of your car.
•  Clean, no-BS engine bay look – TIG-welded brackets, and stainless hardware give your bay a simple, purposeful look that doesn’t scream “cheap eBay kit.”
•  Incredible Sound - The intake amplifies the turbo induction noise and "blow-off" valve sound so many enthusiasts have come to expect from turbo cars.
