This instructable is to show how to install a K&N Typhoon intake system in a Honda Civic Si (06 - 11)


Normal factory filter:                            320 km to a full tank and normal HP   (7.11 km per liter)
K&N typhoon intake and air filter:     375 km to a full tank and +7 HP gain   (8.33 km per liter)
Gain: 7 HP more and less fuel consumption



Step 1:

As you can see before there was a common K&N filter with no intake system with a home made adaptation for the oxygen sensor
<p>These things a so worth it on any car, more HP, better sound and more mpgs.</p><p>★★ Signature: &trade; <a href="http://www.007plate.com/" rel="nofollow">Car/Bike_007_License_Plate_Hide_Gadget</a> &trade;★★</p><p>.</p>
yes indeed... not sure about HP, because I did not Dyno test, K&amp;N certifies above 5HP gain, but the mpg were considerably increased in about 20% or mote
