Hello,
I want to change the spark plugs soon and I was thinking of ditching the OEM Bosch for a set od NGK or Denso (both irridium). Is it worth it or does it provide any at least noticable increase in power or reponse over OEM? Please share your experiences
While I´m at it, despide the ugly roads we have here in CZ, I was thinking of getting the Eibach spring kit and drop it 30 / 30 or (15/15) I have the ///m suspension. Anyone have any pictures of a lowered Zetti? 
Thanks a lot
