Hello! I have a question.Get now in the next time (1-2 weeks) my 1.4 16 V 75 HP Lupo, built in 1998. I wanted to ask you what you can do engine technology to increase the performance? It shouldn’t cost too much as I don’t want to put all too much money into the Lupo. Does a K&N sports air filter/performance kit with intake bridge bring something or can I save the costs? Is there anything else you could do? Thanks already in advance!
