Default DIY Air Filter Replacement - 987

FYI on an article I just posted on how to replace the air filter for the 987 Boxster: https://rennlist.com/forums/diy-subm...placement.html

Hope this helps others interested in doing this rather simple maintenance on their own.

Thank you for the post. While your in the engine compartment did you also clean the throttle body? Do you know if that can be cleaned in a conventional manner, ie with throttle body cleaner and just moving the flap or is there any hidden intenal sensors that will be fouled up.

Are you familar with the flap delete or snorkle people have mentioned? I have not found any specifics on this related to the 987. I recall a year or two ago some discussion about removing the plastic behind the intake grill, but don't find the benefits to surpass the posibility of drawing debris or water into the engine.

Thanks so much Litium - I am new to my 987, after years in a 993 Carrera, which was just a bit too complex to do much with. and want to do a few bits myself.

Your guide is superb - now - come on - do two more, one for oil change, and one for plugs. Best wishes - Nigel, England.

Yep, I echo the above sentiments - thanks for posting. Your instructions for accessing the engine intself, are better than most others I've seen. I've only had this car a couple of months and was about to dig in there and see what I can find. Your instructions will make it much easier!

I didn't clean the throttle body. Though, once you're in the engine... it's a matter of removing a few screws to get to the TB. I'll probably clean out the TB another time (or install the GT3 TB that I bought a while back).
As for de-snorkel... it was one of the first mods after I got the car. I ended up cutting a small wire screen to keep debris out. Others say they notice intake sound, but I haven't myself. THen again, it may be because I'm using the factory paper filter (vs. the "high flow" filters). I like the factory paper filters. The flow rate is comparably high and at the same time filters out more dust particles... based on some research I've read.

There are some articles out there for the oil change... but I'll take some pictures when I do the change this weekend and post it. Spark plugs will have to wait. I think the change interval is like every 30k miles. So, I'm still a ways off.


BTW, I also wrote an article on removing the front bumper for those of you needing to clean out decaying leaves and debris from the front radiators.

Lithium thanks for the information. In my search for a manual today I came across a thread on renntech that discussed problems of manually moving the flap of the TB given it is electornic. The result would be codes upon startup. It was mentioned to turn the car on accessories and have someone push the throttle down to open it so it could be cleaned with TB cleaner. With that said it may not need to be cleaned without signs of idle issues as it was mentioned that dirt around the parimeter of the body may not allow it to seat properly. Again a 987 manual would shed some light on this matter.

Model years 2005-2012. further 2005-2008 is 987.1 (first version) and 2009 on is 987.2 as they received many updates including new types of engines in 2009 that do not carry the dreaded IMS bearings.
