BMW E30 318iS Heat Shield Only


Use this BMW E30 318iS heat shield as a starting point for your custom intake. This item does not include the air filter element nor intake adapter. Mounting fasteners and 2 gaskets for the AFM are included. This heat shield is the same heat shield from our complete E30 318iS (M42 engine) cold air intake kit . The heat shield fits with the stock M42 radiator, but does not fit with the larger M20 radiator.

A blank version (pictured) is available with no intake hole to accommodate custom placement of your intake hole(s). Rubber stripping is provided for the blank version for those who choose to cut a circular hole and pass a cylindrical intake pipe through. The rubber stripping can be placed on the inside of the hole to protect the intake passing through and to provide a neat appearance.

The heat shield geometry retains a clear view of the stock M42 coolant expansion tank, so the level is easy to read. A rubber bulb seal helps to seal out hot engine compartment air.

We use 0.040 inch thick aluminum in our heat shield for light weight, but utilize part geometry to maintain strength. Borrowing from our engineering experience in aerospace, solid mil-spec aircraft rivets hold everything together.

Engineered and handcrafted in Austin, Texas.
