What are doing to adjust the MAF housing diameter or are you doing a tune?

It's tricky to find one of these as a 987 take off as the correct size housing is required to have the car run properly.

...I need one as well

I used a 2000 540i bmw housing. Cheap from ebay. Mine works great. I by no means have stock piping but It is working for my application with out a hitch.

Will the BMW tube connect to the 987 airbox?

I would like to avoid cuting off the end of the 987 airbox. I plan to flash my DME with the 996 flash & tune from there as needed. It would be easy to cutoff my 986 MAF tube & plumb it in but I want to keep it as oem looking as possible for CA smog checks.

I know there are 100's of disgarded 987 MAF tubes laying around 987 owners garages.

Okay hopefully the 987 housing diameter matches up the the 996 tune requirements...it is around 3.25" as I recall. Let us know how the tune works and there is problem running it on a 3.2L and all the ramifications

I wonder what they do to replace them with and why?? I need one but I plan to sleeve it down to match the 986 3.2 DME

not alot available for aftermarket intakes for the cayman/987 (already is a very good cold air intake) so not many used mafs on the market. the place to ask is via a wanted ad at planet 9.

ps, if you are gonna push a new base tune on your car, try the 996 x51 tune - raises redline by 200 rpm.
