Frequently Asked Questions (FAQs)

1. What is a breather filter car?

Breather filters are small versions of the induction kits for the main air intake. They are designed to attach to the rocker cover on an engine via a ventilation tube. The airflow through the crankcase removes the gases which are formed as a by-product of the combustion process.

2. What does a breather do in an engine?

To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap. Many breathers had a cup or scoop and were located in the air stream of the engine radiator fan.
