im new to this so try to be patient with me while i learn this site, i have a 1996 z28 A4 and it has slp shorties on it, did they come from the factory with them already on there or was it a special order? and my intake tube says gigliotti on it, which from what ive read, offers no HP increase at all.

 

No, it did not come from the factory with headers. A Cold Air Intake (CAI) (like your Gigliotti) should help with a little HP.

 

The G2 CAI (L.G. Motorsports) was simply a tube that kept the stock airbox behind the headlights, and a new cover for the airbox. Did not include a new filter panel.

It generally got bad reviews, but I never tried one. I have the original G2 literature from the mid 90's, and it was $240.

The SLP headers were strictly aftermarket, not factory or dealer installed.

 

I didn't realize the G2 thing was so minimal as compared to other CAIs. I would doubt it having much effect.
