Most of you have probably been to a few websites that teach you how to make a custom cold air intake for certain cars.
Basically, mine starts from the MAF sensor and ends at the fender with a nice cone filter from 3A Racing (K&N out of stock at Kragen). It's actually a pretty easy thing to do -- all you gotta buy is about 3 ft. (room for error) 2 inch inside diameter ABS straight piping, 2 90 degree bends, ABS couplers, and if you want, some ABS glue (not really necessary tho). ** The hardest part of the experiment was thinking of something to use for the MAF sensor adapter. I was browsing the internet, and I found a tutorial site that used an object that looked like a pipe with a circular plate attatched to the bottom. I went to Home Depot and found something in the plumbing section called ... get ready ... prepare yourself ... a shower drain. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> All I had to do was drill 4 holes on the drain that matched up with the screw holes on the MAF sensor. So, the adapter was now connected to the MAFS. Next, I used a coupler to join the end of the adapter to a (approximately) 8 inch pipe. That pipe was connected to a 90 degree bend (the straight pipes and the bends connect strongly by themselves -- no glue or couplers needed). This bend was connected to another 8 inch pipe that was directed downward -- through the hole where the resinator used to be, and down into the fender area. Another 90 degree bend was connected to this pipe, so that a hole was facing the front of the car. Finally, I connected my $30 3A Racing Cone Filter to the 90 degree bend using the supplied brace. Long story, eh? Well, not all these steps were taken in this order. I just wrote it this way, so you could get a pretty good picture of what the whole thing looks like. If you still don't get it, I can take pictures with my dad's Polaroid Camera, scan them, and upload them somewhere. But yea, if you were wondering, I haven't gotten a chance to accurately test my "mod" yet because it's been raining, so the floor has been wet. Meaning, that whenever I "punch it," I lose traction. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> I'll post updates tomorrow if it's not raining. Here's my total price list... 1. 5 ft. ABS piping (2 inch inside diameter).....~$2.00 2. 2 90-degree bends.....................................~$1.50 3. 3A Racing Cone Filter...........................$29.99 plus tax (at Kragen) 4. 1 piping coupler (2.5 inside diameter | fits pipesw/ 2''id) ...........~$1.00 5. 1 shower drain................................~$10.00 I think that's about all there is to it. I'll update this if I find any mistakes <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> If anybody plans on trying to do what I just did, or if you have any tips, plz reply. By the way, you can buy most of this stuff at your local hardware store; just make sure they have a plumbing section. However, my local hardware store didnt have any shower drains, so I had to drive to Home Depot and buy one there. As for the air filter, that's pretty much up to you. The only reason I bought a 3A Racing filter is because it was cheap (relatively) and because Kragen didn't sell any K&N Cone Filters that would fit the custom piping (they have a low supply of K&N stuff). I guess I saved myself... what... like a hundred dollars -- something like that. Besides, it's better than stock, and that's what I was trying to accomplish with this project -- something that's better than stock and cheaper than Injen <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> On another note, some guy in a civic cut me off, so I started tail-gating him for a while through neighborhood streets. All I can say about this is that heel-toe'ing it through turns really helps. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> Anyway, we came up to a stop light -- it was red for like 2 seconds -- but he ran it anyways. Either A). I scared him |or| B). He wasn't paying attention. I'm pretty glad he didnt get into an accident - no traffic. |

well, here's my ultimate struggle... i still think that the piping that goes across the radiator does NOT help the cold air at all, so my "intaking from passanger side" is yet to be finished... after i get a sleadge hammer for the battery bracket...
p.s. where's my video! hand it over or die, mrmigs... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> |

Putting the pipe infront of the radiator does provide a lot cooler air. When your engine is running hot, touch the fins of the radiator. You'll find there's no possibility of burning. Plus, when the fan kicks in, it sucks more air through the radiator, and that air is noticeably cooler than what's inside your engine compartment.

Meowth, Erik said that he hasn't had his Video Studio or whatever class yet. He'll be back from senior retreat on tuesday or wednesday, so I'll ask him again later.
