Hello.

Sorry if my english isn't that good, but im not from england.

I have a quistion.

I have a ford fiesta mk4 1.3 endura.

If i put a open airfilter on it.

Is it than just plug and play or should i make some fuel adjustments.

Cause im afraid that if i put one on it, the engine need's more fuel cause its getting more air.

And a nother thing, if i put one on it will it perform better.

Or whil it just make a nice sound?.

Thanks for your help and sorry for my poor english.

Gerard.
