well i would imagine the hose will be the same size, why dont u go and have a look???

And induction kits dont make the tiniest difference anyway.

Depends what induction kit, but a Pipercross one will fit both models.

Depends what you\'re after. They de-restrict the airbox, give you better throttle response, last longer than paper elements, sound better....

The improvements a Induction kit causes:


1)Improved fuel usage, no way round this, more air = adjustment of air fuel ratio so more fuel is injected.

2)the heavy foot syndrome, induction kits sound nice when pushed so you realize you tend to blat about more for cool sound fx

3)Blocked lambda sensor, increased airflow = more micro air particles rushing over lambda sensor, over time this leads to increased junk which blocks the sensor leading to even more increased fuel usage as it cannot correctly tell air flow.

4)Hot air, The induction kit drags air from the engine bay, the engine reingessing hot air doesn\'t help with temp problems in summer months when sat in traffic etc. All of these things create extra strain.

I have an Induction kit fitted... But Ive bought it now so might as well use it.

Next time I think Id just go for a really good panel filter in my air box instead!

I do have a K&N Panel filter that\'s practically brand new if your after one :)

i like em, and think they make the difference, ive had a k+n on my nova 1.2, and corsa SRI. i liked the sound and never really caused me any trouble. i have a \'green stuff\' induction kit on my new engine, and have found that the butterfly valve needs cleaning once a month or so

id say if the induction kit fits on to your 1.2 (which id say it would) theres no problem in using it :thumbs: good luck mate, let us know how you get on

Improved fuel economy - the engine has to do less work to get the same burn. Reset the ECU and let it teach itself the new AF ratio from cold.

And that\'s a bad thing? People are in direct control of how they drive. If their new drive style is detrimental to anything, it\'s something they\'re able to resolve.

What\'s blocking the lambda sensor? Any problems with mixture are resolved in #1.

Engine \"strain\" is negligible. Intake temperature doesn\'t vary that much from having a typical factory airbox to having a cone filter.

You\'ve said all that yet you confess to still using an induction kit? You must be killing your car and your wallet with all that fuel wasted, blocked sensors and strain on the engine.

The whole idea of losing the airbox is that you\'re derestricting the intake system. Even if you drill the airbox, all you\'re doing is losing air pressure so the system works less efficiently.

If it\'s been used then it\'s probably dead and needs cleaning - the service life on them can be worse than the cheap and cheerful paper elements they\'re supposed to replace!
I\'ve seen a leading cotton gauze rival to K&N clog within 5,000 miles. Quite pathetic considering.

Stick to a well oiled foam filter.

Depends how you\'re measuring your differences. If you\'re main goal is power gains, then changing the engine itself will have the most difference.

Excuse me? :shock: If you\'re having to regularly clean any component AFTER the air filter then you seriously need to get rid of that air filter NOW!
Sounds like it\'s not doing it\'s #1 job... FILTERING AIR!

You have still got the receipt haven\'t you?

I would reply to all your comments Joff but there are pretty much your view as mine is mine.

I will comment on your last comment thou

A K&N Panel filter is guaranteed to last for a million miles same an an 57I induction kit, as such with regular cleaning its more than a match for other \"Replacement\" filters.

I bought a Induction kit to see what it was like, now after owning it its silly to sell it and return to stock after my air box was damaged anyway which is why it was replaced. Just trying to pass on what Ive noticed, IE I don\'t think they are worth the extra money :)

Your entitled to your option :)

Well my view is based on experience of working with and results of testing 80% the air filters out on the market...

Yes, so it\'s a lifetime filter - I don\'t doubt that. If it ever did fail, a call to K&N would see you get a replacement in the post.
My argument is that as a cotton gauze filter, it\'s notoriously bad for dirt load. Having a single layer of filtration medium means that compared to paper and multilaminate foam filters, it\'s always going to lose out on the longevity tests. Worse still, as it starts to clog, it flows less air.
Tests we\'ve had carried out by MIRA prove the equivalent Pipercross filter will continue to perform three times longer than a cotton-gauze filter (in this case, it was a K&N).

Ok, so you can clean them. Fair enough, but since the dirt load is so bad, you would certainly hope the filter could be cleaned! Can you just run it under the tap..? Ah no, you need to buy the specialist cleaning fluid and \"recharge\" oil... which is a messy job and over oiling can cause contamination of sensors along your inlet tract (like the air mass meter, etc).
Over oiling is a danger with all reuseable filters, but with foam filters you oil the outer (dirty) layer, with cotton-gauze (single layer only) you\'ve got no margin for error.


In the six years I\'ve owned the Corsa, I\'ve had nearly ten types of filters and without a doubt the induction kit is the one I\'d pay for.

[quote=\".\"]so what induction kit you got then? a viper???[/quote]

Yes, at the moment. Depending on whether I get time or not, I\'ll come up with a VIS kit for the XE in a Corsa... otherwise it\'ll be a custom airbox fed by my bonnet scoop and no induction cone in sight... :wink:

Out of everything on the 1.6 engine, I preferred the BFO cone!
The car drove better and sounded great.

Everyone moans about \"hot air\" and \"flat spots\" - in reality, probably only two people actually experienced anything like this and they were driving in South Africa and had the same problems with the standard airbox anyway. The rest just cut and paste... :roll:
