If your 2007-2009 Acura MDX with the 3.7L V6 is leaking power steering fluid or making whining noises, this pressure hose assembly is exactly what you need. It directly replaces the OEM part numbers 53713-STX-A01 and 3401214, so you know it's going to fit perfectly without any modifications. The construction is seriously heavy-duty - multi-layer reinforced rubber that can handle temperatures from -40 to 310°C and pressures up to 1,500 PSI (with a crazy 8,700 PSI burst rating!). The steel fittings have anti-corrosion coating to prevent rust, and the whole thing is designed to last. Installation is pretty straightforward if you're handy - just remove the old leaking hose and bolt this one right in place. Fair warning though - we recommend professional installation if you're not comfortable working on power steering systems, and we don't include instructions. Make sure your vehicle matches exactly - 2007-2009 Acura MDX with the 3.7L V6 engine. This isn't some cheap aftermarket part that'll fail in six months - it's built to handle the demands of your SUV's power steering system for the long haul.
