2006 Honda Civic Sedan - Install

Pop open your trunk and remove the carpet so that you can access the rear shock towers. Loosen the 14mm nut on top.

There's a 14mm nut attached to the bottom of the shock, too. Loosen this, slide the shock up and be amazed as you easily remove it.

You can now pry the rear spring out. Take the upper and lower hats and put `em on the new HFP spring and maneuver the new spring back into place. You'll notice three nubs on the bottom spring perch. Line these up with the holes in the base. These nubs won't go into the holes at first, but they will fall into place as you go about reassembling the suspension.

Now go and reinstall the rear shock. You'll need an allen wrench to keep the top 14mm bolt in place as you tighten it. The bottom 14mm bolt can be tightened normally. Now go and repeat all these steps for the right side, put your cowl and rear trunk carpeting back in place and sit back and enjoy your lower, better-handling Civic.

Fujita recommends disconnecting and removing the battery first. We didn't `cause we're gangster like that. From there, loosen the clamps on the intake tube, disconnect the hoses and unplug the harness from the mass airflow sensor. You'll now be able to remove the intake tube from the car.

Get underneath the car to wrestle the air inlet tube out of the car. Or you could follow Fujita's instructions and remove the battery. Apparently this tube is pretty easy to remove if the battery is out of the way.

Remove the coolant and crankcase plenum. Replace with the Fujita-supplied 8mm heater hose. Then go and add this vibration mount onto the bracket.

Now you're ready to remove the MAF sensor from the intake tube and screw it on to the Fujita pipe. Do it. Do it now!

Use the t-bolt clamps to install the 2.75-in hose onto the throttle body. Attach the filter to the Fujita intake pipe and slide this unit into the hose. Gently, now.

Make sure everything is aligned and then tighten it all down. Attach the factory vacuum hose to the intake pipe and use the 15.9mm vacuum hose to connect the intake pipe and valve cover.

Plug the harness onto the MAF sensor. Reconnect your battery if you did this install the right way. Voila! You're done! This is what everything should look like after all is said and done. Now enjoy the "whoosh" sound your car makes every time you step on the throttle.
