cylindrical vibration mount for airbox
2 Attachment(s)
old cylindrical mounts for the airbox standoffs seem to be
a common problem on 928's.the result is airbox not aligning up with the maf causing vacuum leaks etc. a recent post discussed where to purchase new ones.they werent exact size needing washers.not that thats a bad thing. found a company(no affiliation) that offers exact metric size cylindrical mounts that porsche used. http://www.vibrationmounts.com advanced antivibration components: METRIC Cylindrical Mounts part number is: V12Z02MFF303010 30mm 1.18 inch (length)* 30mm 1.18 width m8 thread price: $2.55 each |

Whoever posted that the factory part is the wrong size didn't try hard enough. The part number is 931 110 191 00 and unless it is mis-bagged by Porsche (and that can happen) it is the correct size and doesn't need washers. Now, if all this pertains to pre-87 then I have no comment.:icon501: |
Real men move the motor to make the airbox fit.
Well thats wot it feels like. Apolgies to WK for the blatant plagiarism. |

If there is an intake leak between the airbox and the mass-air sensor, it is for more-likely due to the rubber gasket on the bottom of the airbox than the bonded-rubber standoffs. from the manifold inorder to align the bolts in place.rubber gasket obviously can be a problem too. |

(Oh, and BTW, since they are "all over the place" at a Porsche shop, when one breaks the mechanic will grab one out of a pile, not check it and just throw it in. Guess what happens on an early '87 with its fuel rails mounted by bonded rubber buffers to the intake if the wrong sized buffers are used?) my mounts were so warped along with probably others that it actually lifted the maf from the manifold inorder to align the bolts in place.rubber gasket obviously can be a problem too. The S4s work exactly the opposite of the S3s. With S3s, the expectation is that the mass-air sensor and air box are removed as a single unit. Correspondingly the S3 has a different mechanism for sealing the mass-air sensor to the (metal) air guide (i.e. a big-assed o-ring that doesn't care if the MAS is straight or not.)
