I know there are alot of DIYs on the forum regarding intakes. And I have searched, just haven't found one that I was looking for. I know about the Darintake mod, and I know people use a cone filter as well. What I'm looking for is a way to use a cone filter inside the stock airbox this way I could have both the Darintake mod and a cone filter. Any help/pics is appreciated. Thanks guys.

Dont think you will be able to fit a cone filter inside the stock air box. If you want to keep the airbox then try dropping in a high flow panel filter. Check out the blinktek heatshield, most people love it. Using a cone filter without using a heatshield or even using the stock heatshield will cause you to suck in hot air. Sound is really the only thing you will gain.

Ok cool thanks man. I'm probably gonna go with a cone setup with a Blinktek heatshield in that case. How come in some pictures I've seen, some people have a breather filter and some don't. I read somewhere that it has to do with the SAI. Not really too familiar with this. Is it necessary to have this breather filter?

Some b5's have a SAI system. Not sure when the SAI was added/removed in the b5 lifespan, but my 99.5 did not have it. Simply if you have the system, add the breather filter to the open hose. If you do not have the system, you don't have to worry about it.

Great to know. Now with that figured out, I already have my parts picked out. Now all I need is the funds lol. Thanks for all the help dude I appreciate it.

2000 was the first year with SAI.

Thanks for clearing that up man, now I could stop going nuts searching if the '98 has it.

The 2.8 has SAI in 99.5. All 30v's might IDK. Not that it really pertains lol

Lol yea I have a 1.8T anyway so I don't have it
. Another question. I know the b5 1.8 MAF has a 2.75 inch diameter (so I've read). Could i use a 3" mandrel bent u pipe and a 2.75" to 3" coupler to join them to a 3" diameter cone filter? (I'm gonna get a Fujita cone) That shouldn't affect anything right? And as far as the pipe goes, I found a few different lengths, would 6" legs before and after the bend be too short? Thanks.

The MAF is in fact 2.75". When I bought a 2.75" AEM dryflow filter, it fit over the MAF perfectly(no U-bend). So I see no reason why a 3" - 2.75" coupler would not work. Fujita are a very nice brand filter. As far as the length of the U-bend, I am not sure. Maybe try measuring out the amount of room available for your setup?

I dont know what the price is on the Fujita filters are, but I am selling an HKS 70mm one in the classifieds (NIB). So its basically 2.75" if you wanted to keep it all the same size through.

I already ordered my Fujita filter dowsett, thanks for letting me know about your HKS filter though. So before I start this project, I have another question. On the top of the airbox, what is that rubber circle seal with the hose running into the box and how could I go about getting it out? Here's a pic. Its the part under the ICM sensors. TIA

Just pull it. Get your fingernails under the edge of it and it should pull out. Possibly use a screwdriver.

I use a standard screwdriver for the grommet. You just slid it in and under the lip of the grommet and once it starts to pop up, you just pull it up. Once you have it out you will see the wires/connector that clips onto the MAF, unclip it and pull the whole wiring assembly out of the way.
