Anybody familiar with this old school technology? I have one on my car and I'm trying to determine if I should leave it as is (seems to be working just fine) or get rid of it if its causing more harm than good.

For those not familiar, this kit came with an electric module that replaces the stock high speed relay and is designed to switch the fan on immediately after start up. Once the car reaches a traveling speed of approximately 30 - 40 mph, the fan will shut off via the "airflow pressure switch" mounted behind the grill. Basically, fan operation is revised to cool the engine to a minimum of 160* whereby preventing detonation and subsequent ignition retardation (according to the product literature).

Should I leave it alone or replace it?
