Not all engines are the same and you want to make sure your Precleaner fits your engine like Cinderella's slipper, perfect... or should we say your Cylinderella.

We have run the numbers on CFM consumptions across all types of engines. In fact, it is the science we pride ourselves in. Decades of field testing forged the range of different Series 9000 Precleaners and adaptations to perfectly match the environment and CFM requirements of each engine to maximize particle separation. It's the Spin-Science applied across the design of the Dome and rotor that makes The Sy-Klone Series 9000 the market-leading engine Precleaner*! (or PreFilter*..  potato-potato? ;-p  depending on how you want to say it. )


Adapters are either included in the price of the item or can be purchased separately.

Easily added to universal snorkel kits like the Safari, RuggedRidge, AEV, Bravo snorkels. With adaptation, it fits almost all snorkel head inlets.

The snorkel Precleaner is a patented technology that uses the centrifugal force generated by the rotor inside of its dome to separate particles out of the air before going into your snorkel. 

The pre-cleaner uses the airflow from your engine intake to spin a rotor which creates a cyclone style effect inside the dome pushing large particles to the inner wall of the dome where they are ejected. This makes the worries of rain, snow or lots of dusty on a dry day from coming into your snorkel and clogging your filter go away! With this pre-cleaner, you also don’t need to worry about adjusting your snorkel head or dumping out a pre-cleaner that catches debris.

Pre cleaner


You’re missing out!!

For all of you have snorkel what are you waiting for?? This is the best upgrade you can have. I purchased the head mainly because most of the trails in PNW are dusty/heavy dust and this help me a lot i don’t need to worry about cleaning my filter all the time. The snorkel upgrade does the job ejecting all the debris out in the ejection slit just make sure to position it between 7-7:30 o clock. Easy to install and looks bad ass. I also salute Isaac for the best customer service!!!

Easy install, looks and sounds great

Easy install, sounds great when I WOT, looks great, cleaner than my standard snorkel intake, and was shipped fast and packaged well. Nothing to complain about!

Huge difference

So, I’ve loved using my snorkel for the occasional river crossing and frequent desert travels but got to the point where I had to clean my air filter after every off-roading trip with the guys. After installing the pre-cleaner it has significantly cut down on the dust/dirt in my filter. Well worth the money in my opinion.

Works great and looks even better!!!

The snorkel is a must have upgrade for any off road vehicle, but I've always felt uneasy about having a forward facing open face directly into the airflow. This pre-filter is EXACTLY what every snorkel should come with. I've been running it for just over 6 months now and it has been fantastic. It takes a bunch of dust running in a group and takes a beating on narrow trails. The pre-filter also stops people from calling your snorkel a "dorkel"
