Nice n Toasty

Firestorm heater works very well and install went better than I thought it would. The 3 speed fan is powerful and it is nice to have the different speeds to pick from. I would definitely recommend this heater.

Let there be heat

2018 RZR 900: Install takes some time but is straightforward as was already mentioned. The kit was complete with the exception of one drill bit. No big deal. I do wish they would have mentioned the bleed screw above the exhaust manifold, because I needed it despite their priming technique. I found the screw from a forum. Watch your temp closely after your first start. The install looks clean and professional. The thing definitely makes some heat once the machine is at full temp. You will need the bypass on warm days. Two complaints, the fan speed doesn't change a lot. 1 sounds nearly the same as 3. The fan will run without the key on. (It's tied to the 12v port) Everything for these machines is expensive, so I'll let you decide if it is "worth it". It looks great, and heats well.

Comfort heat

Install was pretty straightforward, it took me about 8 hours but I did take my time to make sure it was a clean process. I would suggest picking up some spare rubber to protect the new rubber hose you will be routing the length of the rzr. There are several dangerous locations under the rzr for a rubber hose but you don't really have any other options. Just make sure it's well protected and tied down to avoid movement. Instructions provided good detail on how to prime the new heater core. I was able to accomplish it on my first try. (make sure you have about 4 sets of vice grips or clamps to close off the 5/8" hose)
The heater runs smooth, I really like the defrost capability. It got up to temp fairly quick in the driveway at an idle. I can't wait to take it for a rip and see how hot this thing will get. I'll update this after my first real ride.
