The Honda Civic Si was given Top Safety Pick by the Insurance Institute for Highway Safety. The practical sport compact sedan has a responsive and quiet ride, but can transform into powerhouse when necessary.
K&N Engineering has designed a high flow air intake system (69-1014TS) in powder coated silver for 2006 through 2011 Honda Civic Si models with the 2.0 liter engine.

Power Gain Chart for Honda Civic Si 2.0L with K&N Air Intake
K&N dynamometer testing shows an estimated gain of 7 horsepower for 2007, 2008, 2009, 2010 and 2011 Honda Civic Si with the 2.0 liter engine @ 6700 RPM. The air intake tube has a CNC precision machined billet mass air adaptor and a radiused filter adaptor which smoothes the air flow entering the tube.
The heat shield isolates the K&N air filter (RU-5147) from the engine compartment. The engine bay layout of this vehicle places the air box in the back, up against the firewall. Here, it would be subject to lots of heat and little, if any, outside air. To counter this, Honda uses a flex hose that leads from the front of the vehicle to the factory air box to allow for a steady supply of outside air. The K&N cold air intake system takes advantage of this system by reusing the fresh air hose and connecting it to the base of our heat shield thereby supplying the K&N conical filter with cooler outside air the same way the factory system fed the stock air box when it was in place.
