Much like the sharpened blade that it takes its name from, Polaris's RZR is a purpose-built tool designed specifically for making precise cuts through the rugged wilderness. The 925cc torquey twin paired with forced induction, knobby tires, and long-travel suspension, all placed neatly in a fun-sized chassis makes this side-by-side the ideal specialty tool for off-the-grid excursions. Much like an actual razor, though, this machine needs constant honing to retain its sharp performance, and in this case, our whetstone is the intercooler.
The OEM intercooler is one aspect of this rugged rig that can dull the performance of your turbocharged RZR. Of course, it's not necessarily in terms of cooling power. Still, the high demand for this vehicle across treacherous terrain knocks this intercooler around enough, which can lead to cracks and leaks in the charged air or, worse, the coolant running through the core.
