Prelude filter mod for DASC

[DustenT]

After a lengthy discussion on 318ti.net, I bought a Honda Prelude filter for my DASC to replace the K&N. Everyone knows the K&Ns don't filter very well, paper filters are much better for filtration.

It's a Napa Gold filter, with Napa part number: 6277.

I needed to drill a hole for the intake temp sensor (1/2" diameter). Pics here: http://180customs.net/v-web/gallery/Paperfilter

Good idea. What is the inside diameter of the prelude filter's tube?

Almost the same diameter as the outside of the MAF. I used one strip of electrical tape around the outside of the MAF to make it super tight, then used a hose clamp to snug it down.

Also i think you can use the stock filter box with a K&N replacement filter for the TI

looks cool.. what made you decide to go for that particular filter? do you have anything connected to that front inlet that the box normally connects to? does your filter rest/mount on something or is it pretty stable just sitting there?

Someone on the Yahoo list suggested this filter. The K&N filters have been getting really poor reviews compared to OEM paper filter, and this filter will flow more than enough for this application. I don't have the factory filter box, I don't think it fits with the supercharger (although it could with some modification I'm sure). The filter is very light, so it doesn't need any additional support.

nice. did you cover up the front inlet connection that the stock box connects to? i'm wondering if other people with aftermarket/non-box intake setups run anything to this hole, leave it open and uncovered, or place a cap or something on it? did you fog your box before installing the dasc?

You don't need to cover that hole. Yes, I had the airbox fogged for about 2 weeks, then decided I needed a supercharger.

I remember reading some very negative information about going with an aftermarket intake as opposed to just running the stock box/fogging it - the filter possibly sucking in hot engine air?.. I've had no problems with my non-box filter for about 2 years now

You realize that I have a supercharger right? Sucking in cold air is less of an issue of supercharged cars because the blower produces so much heat anyways. The gains are minimal, and I like being able to SEE my filter all the time.

On a N/A engine, the stock airbox and filter is fine. If you need to modify it, fogg it.

Could you take some measurements of the filter? Length, dia, tube dia? I have an M42 so I have the AFM, and I don't know how that size compares to your MAF.

Thanks!

Is there any update to this? Will this work with the M42 for the 95ti? Thanks! Eric

Another good filter is FRAM for a 1999 FORD ESCORT...same filter but its orange.

What kind of update are you looking for? If you have the Downing Atlanta Supercharger, I'm sure this will work on the m42. If it doesn't, you're only out $15. Give it a try and post your results.

Will do, I don't have the DASC yet but was looking at getting one. So I was trying to find the best intake and exhaust to go along with it. I just checked my compression and it was about 155 psi on all 4 cylinders (+/- 1 psi), so that got me excited.

BTW I used to have the 91 prelude, and that filter does look familiar. I was shocked when I changed the filter to find that it came with the large circular filter stock.
