So i bought one of the above mentioned induction kits from Angle tuning. My original airbox screws bust off so i thought i would replace it with a CDA.

It makes a hell of a roar on throttle but the car has lost a load of power and to tell you the truth i am well pi$$ed off.

£190 is a lot to pay for something that does not work. Maybe i have it installed wrong, its not back-to-front, but could be something i did wrong. Any ideas?

Know where i could get the original box and top?

Nige put one in my JTD yesterday, make a little whistle thats all for noise, he fitted it and it has made a nice improvement. Did you make a new cold air feed for it or attach it to one the original airbox attached to?

The filter is better than a standard one, so there is less resistance in the box, however it sounds like you might be taking in hot air from under the bonnet instead of cold air from outside. This was the case in my mates Primera when he installed a K&N cone filter, he had more power when the car was first started and still cold, once it got up to temperature power dropped off.

slim, did u attach the intake hose going into the CDA or did u leave it off. when i tested the stock airbox without an intake snorkel, i lost power below 3500 rpms. try it with the hose on.

The CDA is very tricky to work with. This is why I wouldn't be surprised with any outcome fitting a CDA.

It isn't the CDA that isn't working. Actually, the way it is fitted makes the difference. Unfortunately people don't listen when flow dynamic specialists try to tell them.

Anyway if you need some help, feel free to pm me. Eurostyling the importer has asked for help before too.

Well i spoke to Angel tuning and the CDA is fitted correct. The problem i have has to do with the amount of oil on the new CDA filter. I was told today that when you fix the new CDA to your motor you have to run the car with the CDA connected but leaving out the MAF. This will draw all the oil through the filter and to the motor with out damaging the MAF. After a few minutes of running connect the whole assembly with the MAF and off you go.

That really f&%ks me off, the instruction sheet says none of this. Now the car needs a new MAF.

Thats not strictly true. When you called I said it "might" be that this has caused the issue as without seeing how you have fitted it, run a diagnostic its impossible to tell over a mobile phone call! I also never said that the CDA is correctly installed for the same reason.

We fit between 3-5 CDA's per week on Alfa's (I did 3 this weekend alone!) and have done so for the past 3-4 years and have never had an issue like you have described.

You should always run a new oiled filter of any description with the MAF out to start with if you are unsure, especially if you have just cleaned it and re-oiled it yourself, its common sense!

We offer telephone support with any CDA bought from us, some people call, some don't and we have never had an issue with them.

It may be that your MAF was on the way out anyway as the biggest cause of MAF failure on Alfa 156's is broken airbox lids - and as you have just said.... your airbox lid was knackered so you have had dirty unfiltered and oily air going straight onto it for some time. Now the air is going through faster and colder, it may not be reading correctly. I am NOT saying this IS the cause, its just a strong possibility!

My concern is that you have this "hell of a roar" - as you shouldnt have if fitted correctly. You certainly shouldnt hear it above the normal engine sound.

First, just to clear things up, i am not putting Angel tuning down or anything. I am stoked that you could offer some help in the first place.

Second, Common sense not to run a new filter with oil. :mad: I did what the instructions said. When i did my 2.0 K&N filter i just put it in and drove, two years back, no common sense.

As for the roar, induction noise is really, really bad. The highway run was so loud i could not hear my radio on my normal volume settings.

Once more, read my post to see how much i respect your work.

Its fitted incorrectly, or you have a pipe loose as it shouldnt roar at all. Check all your fixings, especialy the black corrugated intake pipe and where you have that routed to.

When you removed the old original airbox, did you remove the intake pipe as well and where have you routed the corrugated pipe too out of interest as its quite tight to get a direct feed on these.

Just a thought.... have you fitted the CDA inside the original airbox......???
Removed the old airbox completly. I did not know i could place the MAF higher up in the induction pipe so i have it just above the new CDA. From the throttle side everything is as it was to the MAF, then the rubber you guys sent me, then the CDA. The black alloy
pipe that came with the kit loops from the bottom of the CDA to where the original feed was. Well close. It does not look too good. I am going to place the MAF higher up just after the bend from the throttle then the CDA and then the black induction pipe. Try loose the original induction pipe with the resonators.
