Porsche Boxster » Porsche Boxster Upgrades

Here is a list of the modifications I’ve performed to my Boxster to make it a little more personalized and user friendly.

• Rolling top up/down relay modification
• Clear side markers
  
• OBC (onboard computer) modification to display outside temp, fuel economy, etc.
• European drivers side wide angle aspheric mirror
• Silver crest valve stem covers – $12 from Porsche
  
• Bumper Plugs for the front plate location to match bumper
• Audio system
• B&M Short throw shifter – Buy
• Foot well lighting
• Removed Airbag Stickers on visors using denatured alcohol
• Removed Intake Snorkel to change induction sounds and perhaps slightly increase horsepower
• Ultimate Cup Holder installed on drivers side – out of the way and works well!
  
• Clear (2003-style) front head lights w/ Amber diffuser filter removed, Philips Silver Vision PY21W (1156) turn signal Bulbs installed
  (before / after picture of internal amber diffuser filter removal)
• Clear (2003-style) rear tail lights
  • Philips Silver Vision PY21W (1156) turn signal Bulbs – silver bulbs that illuminate in amber to replace standard amber bulbs in the front and rear light assemblies. I purchased from AMBulbs.com. (The bluish Sylvania Osram PY21W Diadem bulbs are a second choice.) You may have to break off one of the tabs at the base of the bulb to insert it into the socket.
• Wheel spacers: 15mm front and rear. (Wish I’d gotten 17mm rear, in case ever I decided to install wider 911 rims.) I’d considered 7mm for the front spacers, but that would have been too little of a difference vs. stock.

Upgrades that I’d like to do but will never probably get around to actually doing:

• Replacement soft top with glass rear window – Link
• Zeintop Cayman-style hardtop – Link
• Flashing side markers with turn signals
• Variable intermittent wipers
• 3.4L or 3.6L 911 engine upgrade – PDF Instructions for Porsche Boxster 3.4L Engine Swap
• Painted center wheel caps

Track Accessories:

Magnetic Numbers for doors: 8″ tall, Black on white rounded rectangle background, Gill Sans font. I purchased these from FireBallGraphix. (The number on my car: 808.)

Head Protection: I purchased these from Summit Racing.

• G-Force Pro Force One full face helmet: black, Snell SA2005 rating. I like the reasonable pricing of G-force helmets, their lighter weight due to a composite shell, and the fact that they have HANS (head and neck support) attachments, which was rare at the time of purchase.
• HANS device. Yes it’s less comfortable, but it offers critical protection in unfortunate situations.
• G-Force helmet bag in black.
