... is this seriously what I think this is about!?!?!

hyper.....Take another look at Post #2, then the pictures. The dark round plug in the top of the air intake flex line replaces a kidney-shaped resonator which blocks access to the air filter and transmission dipstick. I coined the tongue-in-cheek "butt plug" moniker a year or so ago during the process of installing the 2" rubber pipe cap in the resonator hole.

Ah... There's no kidney shaped resonator on the 00-05 Deville. The trans dipstick is easily accessible. So removing said resonator, gives Seville owners the vacuum intake sound? Just trying to understand this better. I still want to try to interpret the intake flex-pipe re-routing and see how that could be adapted in the DHS.

Would there be a resonator/silencer equivalent and a benefit to removing that?

Removing that kidney-shaped resonator and dropping in a WIX panel filter results in a half to full throttle sound very close to one of the cute "top hat" filter/pipe hot air intakes. Opening up the airbox and/or running a larger duct from the airbox down to the lower grille area makes things louder.......You WILL hear it in the car, but it's quiet for normal and highway driving. I'd guess you can do some similar work on the Deville and, if you're careful, it will look bone stock to the casual observer.

Wix 46302? How is it higher flow than the OEM or whatever replacement? They look the same (paper element)

EDIT: found your posts.... they have more pleats, thereby more surface area.

I am still looking for how to modify the stock CAI on a 00-05 Deville... it's like a needle in a haystack!

I guess this answers the ductwork question. I'm going to still disassemble the multiple black boxes behind the driver side headlamp to see what's there.

Cheers.

Well good... Cause I have a hard enough time trying to hide my identity when I ... browse... those kinds of stores... Don't wanna have to take my car up there and see if I can find one that fits as well.... LMAO

That's OK, because the transparent red/gold flake models cost a bunch of horsepower in the mid stroke.

OMG

You can buy a nice CAI from Volant Cold Air Intakes for the 01+ DeVilles and looks OEM stock. Very nice stuff, used it before on trucks and been quite happy. Wish they would make a Seville unit...

Here's the link:

The stock air intake is already CAI. With a little work you can increase the outside intake size.

Why pay $350 for hype and no gain when you can do the whole job for $25 in an afternoon ? Sure, a cone filter is cutesy, but so what ???

A fully functional air intake modification is easier on the Seville, and you don't have to go aftermarket, either. Go out the side of the existing airbox to the existing hole into the inner fender sheet metal. There's nice, static cool air in there. Cut the appropriate hole in the side of the airbox before the filter and make a flat foam gasket to seal the airbox to the fender sheet metal. Looks stock.

Regardless of whose "CAI" you run, the intake temperatures run about 6 - 15 degrees above ambient on the highway. In town or traffic, with low airflow both in the duct and through the engine room, intake temps will hit 80 - 90 degrees over ambient. Leave town and the duct temp comes back down to the first figures in a couple of miles at 55. Using a ScanGauge (www.scangauge.com) watch your air temp for a couple of weeks before you start the mod work and then after. You may be surprised at how little you really accomplished. Just because it looks trick does not mean it is trick - you need before and after comparison or it's all hype. More noise is not more power......

Well Sub, I was just saying if someone really wants one and wants a first class looking unit on their Deville, the Volant is available. Whether you will gain much from it? No, idea as only a dyno or 1/4 mile run will tell. I'm sure someone here on the board owns one.

Anyway Sub, as far as the Seville goes. Do you have any pics of the fenderwell air mod? I've done a search on your postings for the lower silencer tube mods and have come up with nothing either. I swear I saw it complete with pics at one time...but the fender to airbox mod I haven't heard of until now.

Thanks for the info.

submariner409 · #29 (**permalink**) 07-25-09, 02:06 PM

Agreed - Time slips before and after is the only way to tell if something is good or bad in the tuning department.......and that ain't cheap, either in the time or $$$ columns.

Compared to the intake manifold, plenum, and throttlebody the air intake rubber ducting is huge, so none of that presents any restriction whatsoever, and installing larger throttlebody bores and/or MAF modification generally set air and mixture codes.

There's really no pic of the side hole intake work - I never took any - the only difference you can see in my car is a piece of what looks like gray foam between the airbox and fender sheet metal.

If you remove the intake piping, filter cover, and PCM and unbolt the airbox the procedure becomes intuitive - there's only so much material you can remove to mate the box with the sheet metal hole, and once you go through the trouble to pull it all apart a half hour of Dremel Tool work does the trick. The thermoplastic is tough stuff. That simple hole nearly doubles the cold air side of the intake cross section, and the earlier work on the lower spigot and hole increases the area even more (the Seville lower airbox mod of 2 1/2 years ago.).

I haven't looked way back, and I tend to delete older pics due to storage limits on-site, but I think Iametarq and a couple of other Seville owners also posted pictures. This was all back in late 06 - 07.
