Hey everyone,

I finally saved up some money to change my intake on my car and I am wondering which one to purchase. I am undecided whether to buy a cold air and then modify it to convert to wai in the winter or just stick with wai. And should I get a K&N filter or just the generic one for now and then replace it later? I know lots of questions but I want to do it right if Im gonna do it.

Here are the choices:

These ones use half of the stock intake so I was kinda iffy on them

These ones replace the entire thing and go directly to the manifold and use the stock MAF sensor:

Also with the cai. would I just take out the curve to the bottom, add another short piece of pipe and then put the filter on it to convert to wai (meaning no modifying of intake bought?)

Thanks guys.
