Some guys are willing to spend whatever money they can on the absolute best parts they can buy. We know those type of guys: They are the ones with the cooler toys than yours or mine. And the stuff on their toys are always the best of the best parts. Recently we saw an "endless dollar" Polaris RZR out in the desert, and it had this bright red round housing with billet caps on either end, and it was just about the nicest air intake we'd ever seen.
We had to have one. The rest of our RZR would be beaten and scratched, but at least we would have the sweetest air intake on our block.
And besides: air-intake upgrades are necessary on first-generation Polaris RZRs like ours. The intake boots are known to have a problem coming off of the throttle bodies of the RZR engines due to the twist of the factory air-filter housings. When we went to replace our air filter with this new BTI air intake, our intake boot was completely off our throttle body as well. Luckily, we think we caught it in time because our engine still seems to be running all right.
For more reasons than one, we were stoked to be sticking on BTI's Cyclone Ultra Filter.

BTI uses a high-quality Donaldson paper air filtering element. It has much more surface area than the stock filter, and some racers believe in the factory-style paper elements for the ultimate in dirt filtration. The billet end caps and billet nut scream high-quality craftsmanship and will be resistant to the wear and tear of off-roading.

When we went to remove our factory air intake, we found that our intake boot had already pulled off of the throttle body. We had oviously sucked up some dirt, gunk, and sand, but our engine still seemed to be running all right (thankfully!). This is a known problem for first-generation RZRs (Polaris addressed and fixed the problem on later models) and something that can lead to complete engine failure if not caught in time.

BTI gives a new billet cradle bracket for the RZR, instead of slinging it from rubber grommets on the frame (factory-style). The twist in the factory housing is what leads to the intake boot falling off the throttle body.....

.....By hard-mounting the intake housing to the engine as BTI does, the twist is eliminated and therefore the intake boot stays on.

The factory intake boot is reused with the BTI system, retaining the Bosch sensor.

The Cyclone Ultra Filter System fits directly under the bed (we removed the bed plastics for ease of install - we suggest you do the same) and under the factory intake hood. BTI also includes a billet snorkel attachment in case you are hardcore enough to attach a high-mount intake snorkel to the BTI Cyclone system. We're not that hardcore.
