    The speakers are definitely the weak link in the system. I replaced my entire system, including the head unit, amp and speakers. I used Focal Poly Glass speakers. Unfortunately, I don't know if they will work properly with the factory Bose amps.

    All the turbo Cayennes have air suspension as far as I know. I have it in my S, and it has been reliable. It's actually an option that I will buy on my next Cayenne.

    I run 18" with my winter tires and 20" with my summer tires. The 18" wheels do offer a slightly softer ride, but I still prefer the look of the 20" wheels. It's really a matter of personal preference.

    Everyone hates the Eagles football team. The Eagles band, on the other hand, is awesome!

    I've got the same mirror in my 996. It's a great mod.

    It's the same for the Bose option.

    The brakes on our 996 and our Cayenne squeal. You can use a product like "Brake Quiet" grease on the back of the pads to help with this if it really bothers you. It lubricates the back of the pads and helps with the noise to a certain extent.

    FWIW, I bought a set of the same wheels from my Porsche dealer that were "as new" take-offs from a new Cayenne. The buyer upgraded and these wheels were removed. They were perfect. I paid $500 for the set, without center caps or tires. My dealer actually had two sets at that price when I bought them.

    It's a number that PCNA doesn't release to the public. I've heard a number of less than 5% for IMSB failure, but I don't know the actual number. I have no idea on the cracked head/intermix issue. I know it's more common on the 3.4L 996 engines, but I have no idea on the number. I suspect it's a very small percentage.

    Unfortunately it's hard to tell which engines will fail and which will not. I've heard many theories about things that lead to head cracks, including overheating due to a failed water pump and others. My feeling is that a well maintained car is less likely to have issues, but it's no guarantee. FWIW - a new engine will cost you more than $10k - it's closer to $17k. Internet forums can really make you paranoid. The vast majority of 996 owners know nothing about the potential issues and they simply enjoy their cars. Sometimes ignorance is bliss...

    Your best bet is to get a pre-purchase inspection from a qualified Porsche mechanic. This will cost you roughly $300, but it will be money that is well-spent. Remember that the mechanic who performs the PPI works for you, not for the current owner. Personally, I prefer an independent mechanic for a PPI, but some dealerships are fine too. The list of potential things to repair on this car can be quite long (just like any 13 year-old car). Make sure your mechanic looks for leaks (for RMS leaks, in particular), checks the condition of brake pads and tires, looks for any strange rattles or noises from the exhaust system or engine, etc. Many PPIs include a compression leak down test on the engine. Check the computer for excessive over-revs of the engine, especially "Type 2" over-revs. An excessive number of Type 2 over-revs could indicate that the car has been tracked excessively or abused. It doesn't absolutely mean that, but again - it's one indicator of how the car has been treated by the previous owner(s). Make sure everything works properly, like the remotes on the keys and other features in the car. I would also insist on a Car Fax, and I would insisit on maintenance records. Personally, I prefer using the Porsche recommended "N-spec" tires on these cars. A set of cheap tires, even if they are new, could indicate that the prior owner was willing to skimp on maintenance. All these things should paint a pretty good picture of how the car has been maintained.

    You should also check the headlight bracket(s). They frequently become loose over time. It has two 10mm bolts that need to be tightened every now and then to secure the bracket. Once they are tight, seat the headlight assembly as mentioned above and you should be okay. I had some connectivity issues in the past, especially when it rained. I treated my contacts with some di-electric grease and that took care of the problem.

    If you browse through the TSB section, you can see the latest list of oils approved by Porsche for the 996. Mobil 1 isn't the only approved oil. FWIW, I use an oil that isn't on the approved list. I use Shaeffer Supreme 9000 05W40. There is lots of debate about oils...
  14. Dennis C
    I live in a cooler mountain climate now, so I run 05W40. I ran 0W40 when I lived in Texas.

    I use Michelin Pilot Sport PS2s on my 996 C4S. They are fantastic. Michelin just released a new tire called the Pilot Super Sport. They are getting good reviews, but they aren't available in the proper sizes for the 996 C4S. You might check them and see if they are available in the sizes you need.

    I'll have to go and check which fuse I used... I used a volt meter to make sure I had a switched fuse. I'll see if I can take a look this weekend.

    I think it's silly for the mechanic to say that the IMSB will fail. That's like saying all engines will eventually fail. The majority of 996s on the road are on their original IMSB and it will probably never fail if the car is properly maintained. There have been some publicized reports on the internet of failures and I'm not saying they never fail, but many people estimate that it's fewer than 5% of cars. I think an upgrade to one of the new ceramic bearings is a good idea (all bearings wear, so it's great to upgrade it if you can), but I wouldn't let it be a deal breaker for you if you like and want the car. You can always do the upgrade later. I wouldn't worry about the transmission being removed to replace the crankshaft oil seal. It sounds like a leaking RMS, which isn't uncommon. The latest design for the RMS is quite good. I had my RMS replaced at about 74K miles. I'm at 114K now and it's not leaking. FWIW - I'm on my original IMSB.

    I left my USB behind the dash. It's easily accessible by removing the carpeted panel by the gas pedal. That solution works well for me, because my headunit only uses the USB connection for map updates, graphics, etc. Nice work on integrating yours into the dash.

    You have lots of options at a leather shop. I had them add seat heaters to my two front seats while they had them apart. It all came together nicely...
  20. Dennis C
    I had my worn bolsters replaced. The leather shop charged me roughly $250 per panel for the replacement. The seats in your photo look different because your seats are supple leather and the one your are considering as a replacement is the standard seat. It won't look exactly the same as the supple leather seat is an upgrade. Also, unless the new seat has EXACTLY the same options as far as electical connections, then it won't be "plug and play". You may have issues with the electrical connection.

    I do replace my windshield frequently on both of my Porsches, but I think it's due to the fact that I live in the mountains and they use gravel here in winter conditions. There's gravel everywhere. In the spring this year, I had to have a new windshield in the Cayenne, the Carrera and my son's 2012 Subaru that was less than 24 hours after we bought it! When we lived in the midwest, I never had the issue. My original Cayenne windshield lasted for 8 years.

    The IMS issue wasn't eliminated until the newer DFI engine was launched in the 2009 cars. IMSB failure certainly could happen in a 2005 car as mentioned above, but it's pretty uncommon. A properly driven, maintained and documented 2005 997 is probably a pretty low risk purchase. A 996 turbo uses a different engine design and doesn't have an IMSB. If you can't afford the 997 turbo, this would be a great option also.

    How about the Sylvania kit? It looks pretty good.
  24. Dennis C
    You won't regret it!

    I had mine professionally refinished by www.drheadlight.com. The results were good. The lights look much, much better. They aren't perfect, but they are better. I'd recommend their service.
