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
