What modifications are involved and are they expensive or complicated?
The modifications necessary to adapt this technology to most any given engine, old or new, is relatively easy. In most cases it involved simply fitting the device in the crankcase emission vent tube. The unit is light weight and compact enabling it to easily be connected, usually in line, enabling the crankcase emission to pass through the device and into the engines air ingestion system before the combustion chamber. Being light weight and compact, it does not interfere with any of the engines accessories or operating systems.
