This part is listed by BMW as BMW part number 13711726205 (13 71 1 726 205) and is described as Genuine BMW Air Flow Meter Intake Boot for E30 325i (including 325is and 325ic) as well as the 325iX all wheel drive model. These were the M20 "i" motor, as offered in model years 1987, 1988, 1989, 1990, and 1991. The 325ic used this into 1992 and 1993, as well.
A crack in this intake boot, which connects the air flow meter to the throttle body, will result in a leak. The accordion like construction of these boots often develops cracks over many years of age and deterioration. Signs of a ripped intake boot may be erratic idle or the engine stalling or not able to idle, as well as a check engine light and poor running conditions. Often the cracked intake boot can't be see from the top of the boot, but underneath.
If you have a ripped, torn, or cracked intake boot on your E30 325i, 325is, 325ix, or 325ic, a brand new original BMW boot is certainly an easy repair.
This is a Genuine BMW intake boot with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
