Are there any members here who use K&N air filter products in their car, either Favorit or Felicia?

I have a K&N replacement air filter in my Favorit. Throttle response and performance have noticably increased.

Too bad those K&N 57i Performance Kits don't exist to fit any of the older Skoda models like the Felly and the Favorit. I'm wondering, though, since the Golf is such a popular car - and I'm pretty sure these kits are made for various Golf models - isn't the throttle body/air intake on the Favorit/Felicia the same as certain VW models that K&N does make 57i kits for? :rubchin:

I got the impression the plastic air filter cover on the Favorit was used on some other VW cars, can't be certain though. With a bit of creativity and big hose clips I'm sure it wouldn't be too difficult to make something fit though.
