CAI setups

Hey all,

Has anyone modified their airbox for improved flow?

How did you do it?

Where the results noticeable?

check that link, instructions all inclusive too. thats what ive done and prob the best ive seen

mels black gti has the AEM Intake on it which gives a very throaty sound and you can hear it suck quite loudly too (nice) as well as the dv (even stock) gives a woosh sound through it.. (getting a 2 made up soon so if u want one...)

yeah I did.chopped about a 5 inch round hole where stupid standard pipe connects,then sikaflexed a induction pipe into hole.must better sound and a little more power.

Does anyone know where a "How To" for smoothing the OEM airbx is?
I have a K&N Panel Filter, so will not be going the pod filter route, although I would be keen for futher intake smoothness!

Ideas...

open it up and look at the bottom,there are a few plastic fin parts,ditch them,,use a pliers,they will click off.and then with a sharp stanley style scrapper.its pretty easy and straight forward.

Hmm - I might give the 3 inch hose a go this weekend...

I used a 3" hose from Autobahn/Supercheap and put it down into the front bar - Didn't make a whole lot of difference imo

i noticed a difference on mine from stock definately. maybe chip difference possibly?

noticed a difference with the AEM intake, but not sure if thats from sound/mental change or really did change, they are proven however so who knows!

I'm also interesting in modifying mine. Keep us updated with your results!

Didn't get a chance to do it on the weekend - I might try for this weekend... If I do - there will be a nice little guide with photos. Stay tuned...

i have a pod filter installed on my R32 and it made a lot of difference. The car is much more responsive and the trip comp says that its using almost a litre less fuel. dont forget to get the ECU reset after fitting somrthing like this

Hi guys,
Just finished installing my boost gauge, and was looking to modify the standard airbox.
Is it necessary/worthwhile getting rid of all the ridges across the lid as well, or just the bottom of the airbox?

Cheers!

Oh, and how on earth do you get the pipe down under the headlight?!?!
I've got a pretty thick loom crossing right over the hole and it doesn't seem to want to move

I was scratching my head thinking the same thing!
Anyway...just smoothed the bottom of the box for now!

OK, so after 30 minutes of worry and a quick 15k run, here are some photo's of my interpretation of the airbox mod...

Smoothed box...


Silicone hose running down the side. This stuff was great! Very strong, flexible and above all, smooth inside to stop turbulence.


This took me a fair while to sort out. Basically I used a funnel, cut the end off to allow the silicone hose to pass though for a snug fit. Then, to get everything to fit I removed the horns and made up a new bracket to refit upside down and pushed out of the way.



Here is the vent back in. I dremeled out the covered slats to increase airflow some more. I might give the silver there a quick spray of matt black paint to stop it from standing out too much.


The view from beneath. I decided not to trim the silicone hose down and that the bend in the pipe should hopefully, in the unlikely event of water ingestion, stop it from making it's way all the way up the pipe. Note the remounted horn (I left the second one out...)


Overall, the car DOES seem to have some improved throttle response but I can't say for any power improvement. Mind you this is on a stock car, so it may be too early to tell. Having said that, the intake noise is great

Hoping to have the car dynoed in the next week or so before I make any other changes. Then car will be getting a stage 1 clutch/flywheel setup and chip upgrade. Then re dynoed. Then installing TIP and dynoed again. Hopefully will get some good information anyway.
