09/28/1999 - 1.9 "Fogged" Airbox Modification - By: Shawn Fogg
Increases the air intake hose into the 1.9 airbox to a 4" diameter hose. That is about a 700% increase in surface area for air to flow through easier.

BabyZ wanted to get her exhaust modified for two basic reasons. One for increased performance and two, so she would sound like the high performance sports car she is.

09/26/1997 - K&N Air Filter for the 1.9 - By: Carter Lee
The K&N Air Filter claims to improve performance by allowing more air to pass through the filter

Also known as the K&N FilerCharger, this new fangled air filter has more marketing hype going for it then it actually delivers.

02/07/1997 - Remus Exhaust - By: Robert Leidy
The tinny, rattly, metallic sound of the stock exhaust was just too irritating. I placed an order with Bavarian autosport for the Remus Exhaust System and once it got broke in was worth every penny.

05/05/2000 - The Fogg/Fong'ed 2.8 Cold Air Intake - By: Nathan Fong
Increased performance, low cost, keeps stock air filter. Can't ignore that combination. With the previous work Shawn Fogg did, Nathan Fong adapted the idea and made a custom air intake for his model year 2000 2.8 Z3.

04/28/1999 - 2.8 SuperSprint Exhaust - By: Bryan Powell
In the never ending quest to find more power and otherwise tinker with my car, I decided to put a new Supersprint catalyst-back (cat-back) exhaust on my beloved BMW Z3. I have a '97 model with the M52 2.8 liter engine.

07/26/1998 - Dinan Cold Air Intake - By: Kevin Keniston
After installing the Dinan Cold Air Intake, I decided to write up some better instructions to eliminate some confusion I experienced, to input some tips that will eliminate the need for a second set of hands, and provide the much needed information left out of the Dinan documentation.

• 06/05/2001 - Cleaning the Conforti Air Intake System - By: Robert Leidy
  I'm a big fan of the Conforti Air Intake System, since installation the unit has not given me any trouble and has offered great performance (plus it sounds good). But the time had come to clean the filter. Thankfully cleaning this air intake is nowhere near as involved as cleaning the dinan air intake.

  The ///M engine can benefit from additional air (mass) intake, however the dinan design concerns me.

• 07/06/2000 - Conforti/Shark Air Intake System - By: Leroy Cubicciotti
  Jim C has obviously gone to a lot of trouble to design a system which maintains a factory appearance under the hood. The black plastic intake pipe attaches to the mass air sensor with factory-like spring clamps and the black shield, with its seal, looks very much like the electronics bay next to the firewall on the right side of the engine compartment. The hose clamp which secures the ITG filter to the intake pipe appears to be identical to the BMW clamp which secures the rubber air duct to the back of the mass air sensor, and the ITG filter itself has a really businesslike look with black foam filter and aluminum trumpet. Very attractive!

  I was curious to see how the M air intake box worked. It looks similar to the 2.8 air intake box, but has some additional performance enhancing additions to it.

• 04/26/1999 - SuperSprint M roadster Exhaust - By: Alan Riley
  The M roadster has a fairly impressive stock exhaust--quad polished tips exit from dual mufflers and emit a mellow note. However, like anything in life, even something good can be improved.

• 01/06/1999 - Remus Exhaust - By: Robert Leidy
  The stock exhaust on the M roadster is pretty good, however I was always wanting a little more rumble and sound. Previously I owned a 1.9 Z3 and had upgraded its exhaust using the Remus brand. I was very pleased with the results and when the itch to upgrade the M roadster exhaust hit me I decided to try the Remus M exhaust.

• 03/05/2000 - Conforti OBDII Reprogram - By: Leroy Cubicciotti
  There may be little that the participants in the web's BMW bulletin boards agree on, but one product which seems to receive almost unanimous approval is Jim Conforti's line of Landshark chips and OBDII programs, so I decided to give Jim's reprogram a try on my M Roadster.
