First, a few pictures of the rust and the pinstripes. : )







Now, on to the air box. : )

I have been questioned as to, What IS the factory Air Box, where is the factory airbox, what is the y-pipe, and where do I find the MAFs. Heres a little pictoral rendition about the factory airbox.

Here we have my engine

Now that we have that squared away, here is the beginning of the intake track of the KA24E.



The three components that everyone asks about are ther Air Box, the MAFs, and the Y-Pipe. As seen above, they're all handily located right next to each other.

Disassembly to change your own filter element is easy. It can all be done in two simple steps. First, locate the four little clips around the edge of the airbox, as seen here.



There are four, unclip them. Next, you need to remove this hose. I suggest slightly loosening the screw, although you can just pull it off.



Voila, now your airbox is open, now you can get out your filter element.



Yay for the filter element, heres the inside of the airbox without the element. The elemnt seals between each half of the box, the bottom half is the uncleaned air, while the top half is the filtered air that is about to be metered by the MAFs, as is partially shown there.

In the top half of the airbox is located the MAFS. If yours looks like mine, you don't need to worry about cleaning it. : ) Although, if you are having idling problems you may wish to check the grounding wire that leads into the little black box attached to it. Two views of the MAFs.

From the inside

From the outside

To remove the factory airbox there are three screws, the Y-pipe has 1 screw. The Y pipe also "plugs in" to the airbox, its not connected and don't worry about breaking anything, just pull it out of its socket to remove it. Here are the screw locations.



Once the Y-Pipe has been unscrewed, it can be removed without removing the Factory airbox.







And then it all goes right back together. : )



Thats all. Any questions?

No, people just buy a bigger one capable of reading more air. If you bore it out and it can't read all the air that goes by, you still have a problem. ; )

These are the same steps I take when changing out my intake system right?

Also, before I use that GOO GONE to remove the glue, what can I use to remove the nasty a** gold pin stripes?

heh, nix the goo gone, Jesse says it takes off clear coat and paint too. I guess I"ll just scrub it with soap. : )

I used my hands, I have a heat gun, and I used it, but for some reason it didn't do anything to the pinstripes. So I painstakingly removed them by hand, there were 35, yeah, thats right, 35 pin stripes. 7 sections of 5. Oh my god does it suck.

Did they come off that easily or did you have to use some kind of tool? If so, what?

You know, I just cleaned my engine with degreaser and it came out spotless. I got $2 degreaser from an auto parts store, sprayed it out, let it sit for 15 minutes, and power washed it. It's gorgeous now.

Nice pick up freak. No one who spends so much tme on these boards and with his "toys" has any time to tend a lawn. Shag carpet it is.

Yeah, I gotta try that degreaser also. Thx.
