Kawasaki

Kawasaki makes small engine parts for the landscape and lawn equipment industry - air filters, primer bulbs, and other OEM components that keep commercial mowers, trimmers, and snow blowers running in Montana’s demanding conditions. Professional landscapers trust Kawasaki for one reason above all others: reliability backed by over 65 years of engineering heritage.

Skip the motorcycle division everyone knows about. Kawasaki’s small engine parts division produces precision OEM components for V-twin engines (15-21 HP) and small 2-cycle/4-cycle engines that power professional landscape equipment. Their commitment shows in the details - advanced filtration systems, meticulous manufacturing processes, and a philosophy that prioritizes quality over cost.

Air Filters That Handle Montana’s Dust

The Kawasaki Air Filter 300057 delivers the exact specifications contractors need: 7-3/8” x 4-5/16” x 1” dimensions with multi-layer paper filtration media and polyurethane seals. Those polyurethane seals matter when you’re cutting through Montana’s agricultural dust clouds or dealing with construction site grit.

This filter fits Kawasaki’s V-twin engine lineup from the FH318V through the FR730V - the 15 HP, 18 HP, and 21 HP workhorses that power zero-turn mowers, riding mowers, and commercial-grade tillers across the state. The precision-engineered seals prevent unfiltered air bypass, while the high-efficiency polyurethane media meets OEM dust-holding standards.

Here’s what sets these filters apart from aftermarket alternatives:

Specification	Kawasaki 300057
Dimensions	7.38” x 4.31” x 1.00”
Weight	0.2-0.3 lb
Material	Multi-layer paper with polyurethane housing/seals
Installation	Snap-in design, no tools required
Compatibility	V-twin engines 15-21 HP

Some models come pre-oiled in Twin Air BIO foam variants for enhanced filtration. The snap-in installation means field replacement takes seconds - critical when you’re billing by the hour.

Cold-Start Solutions for Montana Winters

The Kawasaki Primer Bulb 55-118 solves cold-start problems with precise engineering: 0.75” outer diameter, 0.33” inner diameter, built from fuel-resistant materials that handle Montana’s temperature swings. Compatible with both 2-cycle and 4-cycle engines, these primer bulbs work on string trimmers, blowers, snow blowers, and brushcutters - essentially any small engine requiring Kawasaki part 49043-2065.

The UV and fuel-resistant construction prevents the cracking and hardening that kills cheap primer bulbs after one Montana winter. At approximately 1 oz weight, these bulbs deliver durability without adding bulk to handheld equipment.

Component	Specification
Outer Diameter	0.75” (17-19mm)
Inner Diameter	0.33” (8.5mm)
Height	0.75” (19mm)
Material	Fuel-resistant rubber/plastic
Color	Black (OEM replacement)

The Bottom Line on Kawasaki Parts

Kawasaki’s reputation among professional landscapers comes down to one thing: they don’t take shortcuts. Their meticulous design, durable materials, and commitment to quality over cost means these parts last longer than the competition. That matters when downtime costs money and warranty calls eat into profits.

These parts show up in Western Building Center’s Small Engine Parts department under the Lawn & Garden / Farm category - both the air filters and primer bulbs carry the Oregon brand but are designed as direct Kawasaki replacements. The Oregon connection means consistent availability through WBC’s distribution network.

While Kawasaki Heavy Industries spans everything from ships to aerospace, their small engine components represent focused engineering for a specific market: professionals who need equipment that starts reliably and runs all day. In Montana’s landscape industry, where the season is short and the work is demanding, that reliability translates directly to profitability.
