Hi everyone,

I'm new here so I'll introduce myself I'm a belgian boy from 20 and I've a Seicento 1.1 (pictures will follow).

I was planning to get a K&N open airfilter, but I've done some research and this plan is banned . So I was looking for an airbox and I found this: CorsaForum (Link will follow after my 5 posts)

Here do you find a de-restricted box on a Corsa-forum. After reading this, I'll trying to do this with my seicento. My question to you guys is, have someone experience with this?
Thank you!
(Sorry for my english)

I think it'll probably just make more noise. For better performance (and more noise) look at the GSR induction kits.

Yes, there is more noice, but i've read on many treads that the performance will increase with minimum 3hp (with k&n filter or green filter).

you get more than 3hp increase from a GSR kit

AppleSei, I know that you get more HP with that kit. You get also 10HP more with a k&n kit, but I was just wondering if somebody had some experience with this. Because this is just a temporary solution for me. In the future I'll buy a K&N-kit with an airbox, but the price is now to expensive for me (250€ - 300€). And first a will install a CAT and a remus...

Nobody?

Maybe some people didn't take you serious after your wild claim about the K&N?

Had a K&N fited before - as discussed elsewhere a K&N on top of the bay takes in really hot air & is not really an efficient replacement for the standard box

Ok, thanks for the respons guys!
I'll do the de-restricted airbox thing, but first i'll search for a backup box (if it failes...). So i'll make a guide for the people who are interested.
Thanks!

K&N or any other open filter will draw in hot air from the engine bay - no doubt. But I'm still convinced that it's better to have an unrestricted amount of hot air than a limited amount of cool air.
Best thing is of course unlimited flow of cool air.

Also, I've found from experience that the open K&N lets the engine breathe a helluva lot easier in the end of the RPM-scale. This is especially noticable because I have yet to fit a hotter cam.

But... 10HP from a filter alone? No, no and no. The gain will be anything between 0-5HP over the 54HP indicated by Fiat. On the other hand, very few of the centos only deliver 54HP. My Seicento had 62HP with everything stock.

The cheapest alternative is to glue a good, replacement panel filter in the original box. It produces a more brutal note than any other alternative.
Either that or drill a bunch of holes in the front part of your air box and fit a good panel filter later on.

Either way there will be a difference, although in the hard-to-notice end.


If I were you, I'd start with a full service and start saving money for a hot cam.

I'm aware it may sound a bit strange to start out with the cam, but investing in an exhaust system and filter won't really bring much more than noise - a cam will work fine with both standard filter and exhaust, but the engine will be transformed.

After having gone for a drive in a ~90HP Sei with a C&B 280º cam vs my own that's pushing 68HP with a standard cam (chip remapped, novitec air box, better flowing exhaust)... 54HP or 68HP doesn't really make that much of a difference when the cam is still very mild and boooring.

And while you're at it, have the head skimmed + head gasket, cam belt and thermostat changed. These things will most likely need changing before long anyway.
Yes, it's the expensive way 'round. But trust me, you'll love it.
