Don't laugh.. full pop retail from Porsche is .....
$284.00
I'm very lucky that I'm exposed to a LOT of Porsche cars/parts. It takes a VERY long time to learn this stuff.

First drive
so I finally got to drive my car again, first impression of the 987 air box is a plus. Makes good sounds too. I will have a final install pic in a new post with all my engine mods to date soon. Need to break in the engine first, but I can tell already that it rips!

Congrats!
Are you able to say whether the DME properly adapted to larger MAF housing diameter?

Not yet, it was a short drive of about 2.5 miles. Had to unplug the maf, seems to have failed since it was siting in the garage.

Ordered a MAF off ebay, I should know better, wrong part and its used. Drove it on the highway first time anyway, pulls real well. Still waiting to have the proper MAF installed, then I will follow up again. Snow this week.....

I offered him $100, he said no and countered with $200. No sale....YET.
BTW I posted the pictures in hopes you could better show us where to make the cuts.

Any thoughts in putting the rest of the Cayman intake in right up to the diverter tee? How could one run the diverter flap? I suppose a Cayman tune would be needed...

THolyoak used this airbox on my M97 3.8 986 swap back in '09. He said at the time that no modifications were required to get it to fit in the chassis.
Would I gain anything by bypassing the referenced "muffler," or does that just alter the sound?
I am running the 3.6X51 DME map (as it is the largest engine size that was available on a "stock" Porsche 7.8 DME tune/map). Always wondered what I am leaving on the table by not getting it professionally tuned.
I also have a 3.8 IPD kicking around that I never tried. Any ideas if these two mods would give significant gains? He thinks/thought "no" at the time I picked the car up back then.

Nice looking installation! How much did that set you back? If the muffler fits in your bay I would worry about it....I had thought it would only go in a 987 or was there a special 550 spyder edition box that you put in?
I was specifically referring to the Cayman diverter tee and how to make it work on a 3.2 M96.
Where did you get the hose on the tb ....looks like a good fit

I think we are still working out MAF housing issues. Still trying to put my hands a reasonably price air box and MAF housing from there I will be able to see what can be done
It looks like hell to get the old box out and the 987 in!

Perhaps it is my imagination!

Brad,
What does the end treatment of 987 airbox look like and can it fit up to a smaller bosh (3" dia) MAF housing?....well without it looking like a boch job and introducing losses. It may be a good set up for those not running a custom tune (3.4)

Standard 987S airbox, and generic 3.5" silicone TB hose both from ebay IIRC.

Not sure the 986 or 987 3.2 or 2.7 will benefit from the 82mm tb of the 997 carrera 3.8/gt3 . There was a guy that tried it over in australia and he thought it actually lost power. Fitting the 74mm unit with a silicone intake and cone filter is probably the best solution for a 986 , as removing the air box is much easier than on a 987. The 986 definitely has a stunted performance from the smaller air box and media area , hence the 986 550 anniversary gained power from simply fitting the 987airbox and filter but keeping the 68mm tb. The later 987. 3.2 and early 2.7 987 both used the 68mm tb from the 986. The later 987 M97 engine 3.4 and 2.7 used the larger 74mm throttle body. There is a thread running on planet-9.com relating to a cold air silicone hose and cone filter upgrade for the cayman that suggests significant gain over the 987 air box. This may be worth considering as an alternative to the hassle of buying and fitting the 987 air box to a 986. There may be issues with the maf housing diameter as the 987 uses a larger size and a different type of sensor I believe.

Yes well put...welcome to my world! I am wrestling with this right now. I have the 74 tb and plenum in place but I am trying to determine the real merits of the 987 box over making my own intake, sealed to the scoop of course. Making your own is much, much less hassle. I was suprised to see the Caymans making more power with the cone. Perhaps it is down to the filter element itself.
The main advantages of the 987 box are the huge intake area of the snorkels shaped to the scoop and box volume. There must be some hard to see restrictions inside the box. Actually this huge snorkel may be of use in making my own intake....running to the drawing board now!!
