ok i wanna put a k&n intake system instead of stock? what is the easyest way to do that?
can i jus take that box out and on the stock intake hose put a k&n air filter on there will that work???

Do you just want to add the K&N filter, or a complete CAI system?

I think he'* just talking about buying a cone.

Unless you use a tube to get to colder air, for a n/a system you will do better to just put the drop in filter in the box you have. There is alot of photos here showing various cold air intakes. Your also going to have to bolt down the PCM. I think the best way around this is to buy a system from ZZP or Intense. It'* an item that design isnt critical for your application, so I would go for the cheapest.

I have one that will work for an N/A car, filter, tube, and a gutted box

There ya go FLA. What you need and a very good price.

Best to use a cold air box. If you just install a cone filter to the intake your sucking in hot engine bay air.
