Great fit for a 2005 Honda Element
These fit my 2005 Honda Element perfectly. Solved a small leak issue. I’ve had these installed for about one season so far (winter into summer) and they are still holding up.
The install is simple if you’re confident working on your power steering system.
Overall happy. No complaints

Buy OEM Honda for $2 - Suction side o-ring does not fit right
No good. Suction side o-ring doesn't fit right and immediately sucked air. Spend the $2 at a Honda dealer and get the original orange 91345-RDA-A01 o-ring. Fits much better and instantly quiet power steering pump.
