T-20 or T-10 that is the ?
 

This issue probably isn't worth mentioning, however, in view of the recent threads concerning MAF sensor problems, I thought that this might be helpful to some who are attempting to fix theirs . About a month or so ago, I was experiencing what appeared to be the onset of MAF failure . So, after reading virtually every DIY article regarding MAF sensor replacement, I noticed that every one of them unequivocally called for a T-20 tamperproof torx in order to loosen the bolts on the sensor . The funny thing was, at first I thought that I was loosing my mind going back and forth between bits (not to mention two trips to the local parts store), trying to figure why I couldn't get the correct "fit" on the bolts. Out of frustration I decided to try some different sizes, and lo and behold it was in fact a T-10 that fit my sensor . So, the moral of the story is, don't get confused like I did. Your sensor may in fact require a T-10 torx instead . It's a good idea to purchase a set of them. :ah:

Thanks
 

For the heads up! Wonder if the MY matters? I think a new MAF sensor is in my near future, so great find!

Advance has a set of security torxs for about $10.

Along those lines, why are so many folks having MAF issues? My car is nine years old, with an Evo Hi-Flo cone filter (oiled) and I have never had an issue. Clean living, I guess...

My guess is there aren't too many nine year old Boxsters out there with as few miles as yours. How many miles are you up to now?

You make an interesting point. My vehicle also has an Evo intake, and the last time it was in for upgrades, I asked them to check/clean the filter (yeah, I know, I should have done it myself) . In any case, instead of letting the filter dry thoroughly and re-oiling it, they simply blew it out with an air hose and reinstalled it . In hindsight, I believe that this may have led to the demise of my sensor .

all i can say is Harbor freight . That is the place to get cheapo tools . just got an air powered wrench for like 20 bucks. Do any of you guys run the BMC air filter ? do they cause any kind of troubles ?

BMC should be no issues out of the box (lightly oiled). Just use caution to not over-oil after cleaning. Recommend setting on newspaper for a day or two before inserting just in case on both accounts though . . .

Good luck :)

t-anything has the "hole" in the middle. that's the "security" part of it.

another tip for MAF removal/installation...

save yourself the cursing and put a small dab of grease (something with the consistency of petroleum jelly) on the end of the bit. When removing, it keeps the MAF screws from dropping into the black hole never to be seen again, and when installing, serves the same purpose, but also helps align the screws since it's hard to get your hands in there to guide it.

once finished, the grease (or whatever you used) can be wiped away.

I run a BMC - it could be coincidence ( I think it is as the signs were there before) but my MAF appeared to die about a month after installing the BMC. Will really see if it is the problem after I install a new MAF tonight!

i never did care for any oiled type air filter. seems like every time i used one on my previous cars there would be issues. they let **************** into the motor .

any good high flow filters for the boxster that are not the oiled type. i ran a foam type one on my evo and it worked good with no issues.
