I have traded in my SUV and bought myself a 2008 A4 2.0T.
I have been an auto Enthusiast for many years with everything from lowered speed machines to lifted rock crawler/mudders.

I am very excited about my A4, it has brought the fun back into driving!

A few questions.

1: what is the best oil and oil weight to use for best performance and mpg?
I am used to Castrol GTX synthetic but should I go royal purple???

2: There seems to be some hesitation of the line, could this be from the air filter?
(which obviously needs to be changed)
If so KN&N?

3: What are some cool mods out there that are ether Do it your self or in expensive?

I am something of a 12volt expert. I have done everything from building light systems for fire trucks and police cars to Alarms and now GPS vehicle tracking.
If there are any electrical questions I can help with please ask!

Nice to be here

Mike
