The n54 is 10 years old now and has an amazing diversity in aftermarket performance parts. There are so many things available that it's quite hard to filter down the noise for a noob like me.
After hours of searching on the internets I have made a list of things I assume I want first:
Bigger intercooler
Charge pipe, blow off valve
*********
Intake
192.168.0.1 routerlogin 192.168.l.l
I wonder about your recommendations for these parts?
There are conflicting reports that the intake does any good. Some claim that the factory default one is better than some "performance parts". Is that true?
If I do these upgrades, do I have to upgrade breaks and suspension too?
I'm a noob so please be gentle.
