Auxiliary Fan Kits

Auxiliary Fan Kits: Extra Cooling Where the Airflow Runs Out

An auxiliary fan pulls air through the radiator or heat exchanger when road speed and the factory fan can't do it alone - low-speed crawling, heavy loads, hot ambient temps, or an engine bay that's been packed tighter than stock. The auxiliary fan kits here are electric units, so they run independent of engine RPM and keep moving air at idle when a belt-driven fan is barely working. Fit one to hold coolant temps down in stop-and-go use, after a power upgrade, or to add cooling capacity your original setup was never built for.

What We Stock

This category currently shows 6 products from 2 brands, priced from $113 to $267 - that's the live range for what's in stock right now, not a fixed price. Mishimoto makes up five of the six, with DEI supplying the remaining kit.

Mishimoto's Race Line high-flow electric fans come in different diameters - the 10 inch Race Line fan (MMFAN-10HD) at $175.58 and the larger 12 inch Race Line fan (MMFAN-12HD) at $202.58. At the top of the range sits the DEI Auxiliary Fan Kit with Manual Control (902481) at $266.96, a purpose-built kit for the 2015-2024 Honda Pioneer 1000-3, 1000-5 and 1000-6.

How To Choose

The split here is between a bare high-flow fan and a complete kit. A Mishimoto Race Line fan is the flexible route - you pick the diameter that fits your radiator or shroud, then supply your own mounting, wiring and switching. Bigger diameter moves more air but needs the physical room and the shroud clearance to justify it, so measure before you commit.

  • Standalone fans (Mishimoto 10" or 12") suit builders integrating a fan into an existing cooling setup and wiring their own control.
  • Complete kit with control (DEI 902481) is the vehicle-specific choice for the Honda Pioneer 1000 series - manual control is included, so it's the plug-and-run option if you own that machine.

What Else You Need

A fan is only one part of the cooling loop. If the core itself is marginal, look at Radiators before you add airflow. Wiring an electric fan pulls current, so confirm your charging and power side with Batteries. For plumbing and mounting hardware around a cooling upgrade, check Fittings and Adapters. All of these sit under the wider Engine Components section alongside Oil Filters and Fuel Pumps.

Fitment Help And Ordering

Only one of these products carries explicit vehicle fitment data - the DEI kit for the Honda Pioneer 1000-3, 1000-5 and 1000-6, 2015-2024. The Mishimoto fans are sold by diameter, so match them to your own core and clearance. If you're unsure what fits, call our fitment help line at 813-535-5801 or reach us through Contact Us. Every order ships free, and Affirm and Katapult financing is available through our financing options.
