Lonsda Air Filter Kit for Yamaha Grizzly, Kodiak & Wolverine 2004–2014 — Sponge Filter with Guide & End Cap

Lonsda's Air Filter & Guide & End Cap Kit replaces OEM 5UH-E4458/00/00, 5UH-E4468/00/00 and 5UH-E4451-10-00 for select Yamaha ATVs, restoring clean airflow and protecting your engine.

If you own a Yamaha Grizzly, Kodiak, Bruin or Wolverine from the covered years, this three-piece kit gives you a direct-fit aftermarket replacement designed to match the original form and function. The set includes the sponge-style air filter, a molded inner guide to keep the filter shape, and the matching end cap for a complete seal. Materials focus on durability and multi-layer filtration to reduce inlet contamination while supporting consistent combustion.

What’s included in the package and which OEM parts does it replace?

The kit is sold as a matched set to simplify replacement and avoid mixing old and new components. It replaces the key OEM items so installation follows the original fitment and sealing points.

• 1 x sponge-style air filter element
• 1 x molded inner air filter guide to prevent collapse
• 1 x end cap to secure and seal the filter assembly
• Replaces OEM codes: 5UH-E4458-00-00, 5UH-E4468-00-00, 5UH-E4451-10-00

How does this kit handle filtration and durability?

The Lonsda filter uses multi-layer sponge media backed by a rigid inner guide and a durable end cap. That combination filters particulates while maintaining shape and airflow under operating conditions.

• Multi-layer sponge traps dust and debris effectively
• Metal/plastic guide supports the filter against deformation
• Sturdy end cap ensures a secure seal and long service life

How easy is installation and what should I check before buying?

Installation follows the same steps as the OEM replacement — remove the old filter, insert the guide, fit the sponge element, and secure the end cap. Basic hand tools are typically all that’s required.

• Confirm exact Yamaha model and year before ordering
• Inspect airbox mating surfaces for wear or damage during replacement
• Hand-tighten fasteners to OEM torque specs; no special tools needed

Who is this for? This Lonsda kit is aimed at Yamaha ATV owners who prefer a reliable, complete replacement set instead of sourcing parts individually. Riders who maintain their machines for utility, farm work or trail use will appreciate the matched components that restore proper filtration and airflow. If you need a direct-fit alternative to the specified OEM part numbers for the listed Grizzly, Kodiak, Bruin or Wolverine models, this kit provides an affordable, durable option. Always verify your model and year to make sure the kit matches your vehicle’s original airbox configuration.
