- Cone K&N intake (part RU-2520) ($35)
- 12" of 1/4ID fuel hose ($2)
- spare bolts
- 10mm Socket wrench or 10mm Open ended wrench
- Phillips Screwdriver
This is probably the simplest and easiest way to install a costume K&N intake. K&N intakes should give you better fuel economy, and more power.
First you need to remove the factory air box by removing four (green) screws. Then separate intake from rest of box by removing (blue) screws. Be careful not to shake or damage Mass AirFlow Sensor (red), it is very expensive little thing.
Once you remove the factory air box, inside of top part, there should be a gold plate. You need to get this gold piece out. Simply try to knock the corners lose by sticking a screw driver into the four gold holes in the picture above and getting them lose. However, there are two small nubs that keep the gold piece attached to the box. Take the flat head screw driver and keep prying the two corners evenly. It's ok if you bend the gold piece a little bit, but you don't want to bend it all that much. Keep prying and it will eventually come off. It takes a bit of prying so do not be concerned if you cannot get it off.
Now that that gold plate and place 1/4ID fuel hose around it. Make sure you cut it just right. DO NOT cut it to short, it will leak air in. So take time and sure it just right. Place K&N filter over it and secure it well.
Just make sure there are no vacuum leaks in the intake system. It's a good idea to duct tape the entire perimeter of the cone's connection.
Now the system is done. You should reset the ECU.
