Does it look like it will fit without any modifications, or can you tell? I would love to see pictures of the installation, and some idea of whether it's more difficult to install than a stock AOS!

not sure if it will fit easily... hoping so. I've heard it bolts right up to the engine but issues with clearance for emissions stuff like the air pump, i know a cayman S guy who ponied up for 10 hours labor to reroute all the secondary stuff but have been told that shouldn't be an issue on the older boxsters...we'll see. I'll know more tomorrow. Here is a picture of it next to a soda can for reference, its quite a bit larger than the stock one.

Just following up to see how the motorsports AOS install went. Easy, drop in replacement, some modifications needed or a complete no go?

If installed, can you tell any difference driving with it? Please post pictures of the results when you get a chance

hey, thanks for the reminder... turns out to be a no-go. my mechanic had the car for two days of head scratching and just no reasonable way to make it fit. might be doable on the '05s or newer but no go on my 98. the mounts are completely different and would require some serious modifications. so i'm back to square one. anyone tried putting some washers inside the vent tubes to limit the oil from blowing by?

Unhappy



If it wouldn't work on your '98, I don't think it will work on my '01. When the time comes to replace, it looks like I'll have to use the stock AOS. Oh well...

Thanks for the update

Where in California are you.

Have you seen the 4 page bulletin Porsche put out in 2004 on how to install the motorsport separator. Additional parts are necessary.

TP - don't just leave us hanging like this! Not fair!

Just as an additional, related note - I've got a Greddy air/oil separator that was an aftermarket bit I had installed on a previously owned Subaru WRX. I spent a couple hours seeing if I could install that in my '00 Boxster S in-line after the OEM AOS. The idea would be to have a redundant system in case the OEM unit fails the Greddy unit would pick up the oil and has a visible sight glass to let you see if it's filling up with oil.

Well bottom line is that the Boxster engine bay is EXTREMELY tight. There's just no room for extras like this. My best option was to mount it in the rear trunk next to the coolant tank and run hoses through the firewall. I've got other projects to work on for now, so I put this on hold for the moment, but I'll see about picking it up again later. Not a priority though as I don't really see a redundant system here as necessary. I'm just playing with parts that I already have.

the mantis guys routed the AOS to a catch can rather than into the throttle body. i believe it somehow runs back into the crank case.

Cool... do you know where they mounted the catch can? This sounds similar to what I had planned with the Greddy catch can I have. Basically disconnect the line from the AOS to the intake plenum and attach the catch can in between. You could maybe blow it off to atmosphere (illegal in Cali where I live though) and let the catch can drain in the crankcase, or you could just route the outlet hose back into the intake.

i saw their test rig at road atlanta two years ago; it was some ghetto milk jug setup. their car is a cayman racer; the milk jug was mounted in the stripped out trunk area. not sure what their final setup looks like. you can email stan carmichael or ernie jacobowski at mantissport.ca; maybe they'll give some details. they may even sell their setup.

As I write this RUF is installing a Motorsports Oil Separator 996-107-926-00 in my 2003.

Last weekend I had a problem with smoke at turn 11 of Eagles Canyon. See the photos caygirl posted here -- same track, same turn, same smoke, different car. It's a tight 180-degree left and all was good if I backed off, but heavy on the throttle in second gear and *boof* smoke everywhere.

I'm anxious to see how this monster of a oil separator looks in the engine bay.
