Induction kits.
« on: 06 May 2007, 23:30:07 »
 :-/As previously posted i've fitted a pipercross duccie kit to my mig. This seems to have provoked varied responses. I'm by no means a young man, this is my first ever kit & first ever mig(excluding work vehicles). I'd like to hear WHY any members think it's a good or bad idea.
     I regularly oil change, fuel filter etc & only boot it occasionally. After a full cambelt kit i do'nt want to knacker it so will take any advice on board. Mileage is 97k & i have kept original airbox in garage should i need it.
        No change in running or mpg but if pushing it just alittle livelier mid range & sounds nice, standard exhaust. Most of you will know better than me so i will take notice. Cheers. :-/

Only thing it can hurt is the MAF.  Cone filters tend to be very oily and that coats the MAF.  Can be cleaned, but after a certain point the MAF dies.  Otherwise, if you like the noise then why not!

Agreed, noise is nice. I had an ITG cone fitted for a short time.
As theo says, oil on the MAF would be a problem...

Biggest downsides though would be getting a proper cold air feed, the filter is probably more restrictive than standard (lower surface area) and the noise is irritating as hell on long motorway drives!

I remain unconvinced that they ever improve performance, and in many cases decrease it.  I suspect the noise makes it 'feel' quicker...

They do make a small difference in many cases, but I wouldn't go running out to get one.  Mainly it is just about the noise.

They make a difference on cars when the original is under spec'd.  The Omega has a pretty big filter as standard, plus its fed with nice cold air, unlike most induction kits.

I run a viper induction kit, a bit expensive but better than a cone, has a heat shield to protect it
from engine temp, it's also connected to a 100mm cold air feed pipe which is feed from the front of the car, not everyone likes the chrome intake but i'm getting used to it.  Slight improvement on performance, but only when you get the rev's up, sound's good & not loud on moterway driving :)

I fitted a cone filter (with a cold air feed) to my last car hoping to improve the performance and make a nicer noise. However, there was no noticable increase in performance and the noise was more of a rasp rather than the growl I was after.  I you want more of a low end growling noise then I guess the only way is an exhaust change?

If you are after a little more performance then you might be better off with a non-standard filter in the original box for less restrictive air flow. A K&N panel filter to fit the miggy's box would mean you can keep the box in place and use the existing cold air feed.

Also if you fit and induction kit then ideallyyou need to tell your insurance company that you have modified your vehicle. If the worst does happen and you have to claim then it's possible they'll use it as an excuse to not have to pay out. I told mine I had a 'non-standard air filter' and they said that was fine and didn't charge me more, but at least I was safe in the knowledge they knew and they couldn't use it as a 'wriggling out clause'. (Technical insuance jargon ;))

Hope this helps and feel free to correct anything peeps!  ;D

The thing is, the standard filter is not restrictive due to its size...

In most cases I would heartily agree.  However, on my miggy the folds are really dense and I'm just not sure.  :-/

Nah, that gives more surface area to filter.  They are not so tight to restrict...

 :)Thanks all. Sorry but what is a MAF? I agree with ins. declarations(got 9 hgv points which i do declare)  Maybe a panel filter is a better route, iget no annoying noise @ motorway speeds, only if i boot it. I also want a performance exhaust which are always noisy & need declaring to ins. Car will be @ Lakes meet, ill try & make it too!!! Work tomorrow, bedtime etc... Thanks for giving me your help. Take care. :y

If you gain anything (questionable) by fitting an induction kit you'll lose it again if it's not taking 100% of its' air feed from in front of the rad.

Induction air temperature makes a significant difference to the power output of an engine. A panel filter doesn't cause a problem, of course, because the original cold air pipe is still used but a cone filter in the engine bay will be sucking hot air from under the bonnet, even if you try to duct air towards it. Underbonnet air can get very hot when the vehicle is running at low speeds.

Anyway, I've ebayed myself an AP22 performance meter for very reasonable money so if anyone wants to do a before and after test, and has a suitable private test track  ;) it can be arranged, and might be an interesting exercise.

MAF is a sensor that mesures the amount of air being used by the engine...
