1524 1994-2004 Land Rover Defender 90 Discovery water pumpIf you own a Land Rover with a 3. 9L, 4. 0L, 4. 2L or 4. 6L engine then you have probably have heard all of the reasons they overheat. Some blame the steel liners shifting within the aluminum block. Some blame combustion gases in the the coolant and or the crankcase system. Others point to micro cracks in the block, porosity in the block and a myriad of other reasons. One customer called us to say that he noticed the temperature rising at a low idle

If you own a Land Rover with a 3.9L, 4.0L, 4.2L or 4.6L engine then you have probably have heard all of the reasons they overheat. Some blame the steel liners shifting within the aluminum block.  Some blame combustion gases in the the coolant and/or the crankcase system.  Others point to micro-cracks in the block, porosity in the block and a myriad of other reasons.  One customer called us to say that he noticed the temperature rising at a low idle and he discovered our pumps as a possible solution.  Unfortunately we did not have an impeller for this pump but he has convinced us to develop a hi flow impeller to increase the coolant flow rates to help mitigate the temperatures. 

Flowkooler High Flow pump impeller are CNC machined billet aluminum designed with an increased vane count and a reduced plate-to-impeller clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

Slow speed rock crawling means lower fluid flow and limited air flow.  A good radiator and a hi flow pump will keep your engine temperature down whether you're crawling in the hills near Birmingham or in the desert near Moab.

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Great Upgrade to your Cabin Filter. Fits 2018 Subaru Outback
Size: 9.7" x 9.3" x 1.8"
This is a great filter upgrade to your cabin filter. This is better than the Subi standard part. Fits my Subaru outback. NOTE: Subi marks their filter with an 'up' arrow; however, this filter is marked with a 'airflow' direction. Direction of air flow is toward the blower motor so it will point downward when you install it.

Air flow direction
Size: 9.7" x 9.3" x 1.8"
Good product. Fits fine. This is not a Toyota part so Air Flow Arrows on filter should face down in a 2015 Toyota Rav4.
