987 v 986 Air box

[tommy986]

questions for Brad.

1. can the swap to a cayman airbox be done with the engine in the car?

2. where are you sourcing the cayman airbox? Model year and what price?


thanks

In addition to my questions above, I was wondering if the MAF housing was the same diameter as the 986? if not, do you use the 987 MAF sensor in the 986?

Tommy,

you want to use the CaymanS MAF housing. It holds the same MAF your 2000 car runs.

I happened to have one close to my desk. I'll show you the CaymanS MAF holder and boot, then show you the 986 (side by side)

As far as pricing goes, I expect to pay about half of new when buying these parts from places like LAPD/OK Foreign/PartsHeaven

Part number: 987.110.021.00 NEW Price from Porsche is $560.00

You will find it in cars from 2005-2008 ALL 2.7/3.2/3.4 cars.. all of them..

Stock 2.5/2.7/3.2 utilize a 74mm diameter inlet at the MAF sensor.



CaymanS utilizes a 82mm opening!!!!




Just noticed the spider in the BoxsterS MAF tube.. LOL

If you use a larger MAF housing diameter without reprogramming or otherwise changing the signal, the DME won't be calculating air volume correctly. The car will run leaner than the DME thinks it is.

As promised, pics of the 987 intake transplant to 986S:

A view over the 987 / Cayman airbox, cut to fit into the Boxster. Hole was sealed later reusing some plastic cuts and glue, plus thermo isolation tape.
