HOUSING







The lightweight design of the IHKS housing provides a strong, compact, integral structure for the IHKS components. The Z3 and 318ti system housings are identical in function but have differences in the following areas.

- The Z3 has a dual squirrel cage blower wheel versus the single blower wheel of the 318ti.
- The Z3 housing has a slightly shorter profile.
- The Z3's IHKS control module is mounted on the driver's side of the housing versus the passenger's side of the 318ti.
- The Z3 does not utilize an air inlet microfilter like the 318ti.
- The mounted angle of the heater core in the Z3 system is "flatter" in the housing compared with the 318ti.
