Review: Yes, the Mann C31002 fits 987.1 Boxster S - desertcart Garage says that the Mann C31002 engine air filter does not fit my 2005 Boxster S, a first generation 987 model. desertcart is WRONG! This filter is an exact replacement for the factory filter. It even has the plastic boot that fits over one end. To replace your filter is ‘difficult’, if you’ve never accessed your engine before. Several YouTube videos teach the process. If you already know how to get into the engine compartment, it is an easy job. The filter is in a black plastic housing on the driver’s side (on American driver’s side.) Remove two Phillips screws holding the housing cover, then lift cover straight up. Old filter is held by one more Phillips screw located towards front. Remove this screw. Study the filter, so you will remember how it sits in the housing. Now slide old filter towards front of car, to disengage it from the air intake. Notice that the throat of the filter fits over top of the mating air intake on the car - not inside it. Wiggle old filter out. Clean interior of housing with damp cloth. Put a tiny bit of liquid dish soap on INNER surface of the throat of the new filter to lubricate it. Guys, don’t use WD40 - it’s a solvent. Wiggle new filter into the plastic housing, with the black boot facing front of car and air intake throat facing rear. This, by the way, is a pain - just keep wiggling and it will eventually go in. Now slide the soapy lubricated throat over top the air intake flange. This can be fiddly too, just be patient. When properly seated, the screw hole on the black boot should mate up with the mounting tab. Now reinstall the Phillips screw on the mounting tab. Clean and dry your housing cover, slip it back in place (big tab goes into the mating slot), then replace the last two Phillips screws. Record your filter change in your maintenance log and crack open a cold beer. :-)
Review: fits fine on the 09 Boxster... just be patient - takes time to get everything aligned to get it back in place when you get the old one out. but it is pretty durable, so even when you scrape it against some of the hard plastic and thin metal while trying to get it in place, it stays intact. I'll probably order another one of these when it is time to do it again.

### ⭐⭐⭐⭐⭐ Great Filter!
*by A***. on August 13, 2024*

Although Amazon says this filter doesn't fit a 2004 Porsche Boxster, it actually does. However, you'll need to check the type of air filter your Boxster uses first. The standard 986 Boxster may require the older panel style of air filters. Mine is a 2004 Porsche Boxster S Limited Edition, which has several upgraded parts used in the newer 987 model. This filter is the correct one for my Boxster. The installation is straightforward, but it takes some time to put the car into maintenance mode before you can access the filter. Overall, the quality of the filter is excellent, and I would highly recommend this OEM-quality brand to German car owners.
