CAI installation question

[sierra055]

Hi guys,
couple of questions... I'm looking to install a BMC CDA air intake.
The model that i'm looking at says it's specifically for cars that have a MAF part number of PBT-GF30. I checked mine and it says PBT-GF on the top, but nothing else?? Does anyone know if there were multiple versions?

Also, given that I plan on removing the factory airbox, I notice it has a sensor of some description on the side. What's this for? Does it need to be retained?

Cheers guys!!

Let me know if you get one, because I believe they are out of stock at the moment

[sierra055]

Yeah, I was told that too...
I've found a source in Europe that have 2 models. One is the generic fit CDA85-150 with a 70mm joiner. The other is the CDA SP-05 which specifically states the 1.8T 150/180 and is designed to mount directly to the MAF.
Cost was just over $400au landed.

Anyone????

The thing with 2 plugs on it in the side of the air box lid is an ignition amplifier I believe.

Can't answer your question on the MAF, I do know that the 150 and 180HP engine have a 2.5 inch housing and the 210-225 hp models run a 3 inch. I wonder if that's the numbers you are looking for?

as ive had a few tonight I cant answer your question fully,but the amplifier that is bolted on the side is a temp sensor.leave it hanging away from anything that will make it hot.pm dub20v as he has a CAI setup and should be able to answer most of your questions.
if I think of anything more ,ill post here when I sober up tomorrow!

Will the generic one fit on the Bora V6 ? 400 $ landed is dirt cheap ... maybe a group buy....

[sierra055]

I'm not sure... The BMC website states that it is for cars over 1600cc, so I guess it fits that criteria...

Here is a link to the generic one

And the specific model for the Bosch PBT-GF30

Here is a list of all MK4 Golf/Bora models

Interesting they specify the 150hp ans 180hp models differently? Do our cars need/have a crank case filter?

What do you think of the Carbonio ? There is quite a selection out there. I guess you have to go with whatever is marketed best

[sierra055]

Can't say i've really looked into the Carbonio too heavily, as I want something that doesn't sit in the front footwell. I've heard (not experienced, not backed up however) about hydro-locking etc, so would like something enclosed.
I like the BMC too as although it has the carbon case, it doesn't look too blingy and aftermarket.

I'm going ahead and ordering 2 of these in (the CDA85-150), so if anyone is interested in the second one feel free to PM me. Cost will be $420 landed, which is pretty good as I was quoted around $650 locally + installation. I believe the only other part required will be a silicone adapter to go from the 85mm BMC to the 70mm MAF intake. These can be picked up from virtually anywhere.

Has anyone gone from the modified air box to the CAI? I can't see that the difference would justify that price to me. Yes - the CAI looks so much cooler but I doubt the gains would be all that great. The modified airbox work purfect for a turbo as it has plenty of insulation from engine heat and the filter would have just as much surface area as a pod. Master mechanics - give us the low down.....

I reckon I would be interested in the other BMC. What is needed to make it work with the V6 Bora, anyone know ?

I am still waiting for pics on how to do the modified airbox mod

I'll go and take some snaps tonight but its as easy as Geelong winning the grand final!

All you need to do is remove the airbox (2 or 3 screws), get some 3" flexi tube from your local car-mart, cut some of the plastic away from behind your headlight, feed the tube through and shove the other end into your air box where youve plucked out the crapy plastic thing that currently feeds it.

Piece of punjabi!

Thanks ! Will give it a go when I change Gear oil to MT-90

[sierra055]

I read a really interesting thread from the Polo guys with some very scientific and measured results between the factory intake and a Seat one. Also interesting to note was that the factory filter was actually quite good as it didn't restrict flow too much.
Not sure if there's a similar airbox we could use?

I guess for me i'm after a 2 fold result.
1. Increase in power and throttle response
2. That great induction noise you get
