Deilenberger - As I remember it, 2011-12 Cayennes didn't have a Turbo "S" option, rather a Turbo with the E81 Powerkit listed on the build sheets ($20k+ for 40 horsepower). I did a lot of research on this subject, and never once found an actual 958 E81 intake & Y-pipe being sold separately, only the 957 E81 which I can no longer find online.

I actually have the E81 intake and Y-pipe sitting in the garage. As soon as I can free up some time from work and woodworking, I will get it installed along with the other 100 parts waiting to go on the truck.

While the intake is off, I plan on replacing the plugs & coilpacks, then cleaning the valves since direct injection engines always seem to have higher than average carbon buildup (Renaissance Man's thread on this is the best one IMO).

Do a search for an AllDataDIY discount code - most people pay less than $20. I'm sure Google will turn one up.

Just bought this CTT last month from Colorado, first thing I needed to grab was the usual maintenance items + replace the brand new Scorpion Winters (If anybody wants great condition Turbo II's & brand new Pirelli Scorpion Winters with 3k miles on them, message me!)

Currently in the garage waiting to be installed:
Whole new wheel/tire combo to replace the Turbo II/Scorpion Winters (I live in Austin TX, I needed summer tires!)
Ravenol T-case fluids
All new front & rear Pagid pads, wear sensors
All new coils and plugs
E81 Intake & Y pipe
Full 2.76" Milltek exhaust including bypass pipes
Black painted Fabspeed tips
Gloss black 993 "turbo" emblem to replace all chrome emblems
Gloss black hatch trim piece

I plan on doing these upgrades, then getting a tune that I can flash while on a dyno so I can get before/after numbers. All the tuning companies usually show a cartoon dyno chart, or a dyno from a stock vehicle. I would like to know what the numbers are after doing all the complimentary upgrades.
I had a Fabspeed tune on my last CTT and it was totaled. Right now I'm still researching my tuning options, but I'll make a decision pretty soon!

I just did a lot of what you did - also did the cabin filter and engine air filter (BMC - have two K&Ns leftover).
Make sure you get new bolts and springs for the calipers. Couldn't hurt to do the brake fluid either - 2 points per caliper.
Would love to see pics of the back once its done - I'm trying to get some glossy black akropovic tips off ebay.

If anybody's interested in a brand new E81 intake and Y-pipe, I am selling mine in the Parts Marketplace. Wedding planning & work are taking up all my time, and I just don't have the gumption to mess with the Cayenne any more than I already have.

I'll throw in 8 brand new Bosch iridium plugs for free!
