Hi Guys! Sorry if i talk to you in english but i don't know the german language!
I want make some self made modification.
I want ask you some things about my Golf IV 1.6 16v 08/2002! 77 Kw
What is the best gear oil in your opinion for better shift ? The VW wants G052726A2 gear ioil but what type of oil is it? Is it a sinthetic? What is its grade? Is it a GL-5? Can sosbstitute it with another sinthetic oil like a 75W90?
Can i eliminate the central muffler exhaust and put a straight tube instead of it. Do some gain in sound and performance or i must put also a terminal sport muffler?
If i put an K&N direct ait intake filter (not panel) must i modify the ecu?
Can i eliminate the EGR valve? do it some gain in performances?
Do you know some other simple engine modifications for this model?
Thanks in advance
I know that you are very good Guys in VW techinc!
