Product Description

The No Toil Super-Flo Air Filter Kit is the ultimate solution for riders looking to unlock hidden horsepower in their modern Yamaha 4-stroke. By eliminating the restrictive stock backfire screen and replacing it with No Toil's proprietary Super-Flo polymer cage, this kit creates a high-velocity intake path that significantly increases air volume for improved throttle response and peak engine output.

Engineered for both performance and peace of mind, every filter in this kit includes a specialized flame-retardant inner lining, ensuring top-tier safety without the flow-choking characteristics of traditional metal screens. Each kit comes complete with a No Toil speed knob for lightning-fast, tool-free filter changes, making your trackside maintenance easier than ever before.

Frequently Asked Questions

Q: Will removing the stock screen make the bike louder?
A: You may notice a slightly deeper, more aggressive intake tone, but the primary benefit is significantly increased throttle response and engine efficiency by removing the airflow restriction.

Q: Does this kit include the filter oil?
A: The filter in this kit arrives pre-oiled and ready to install. For future cleanings, we highly recommend the No Toil biodegradable oil and cleaner system to keep the flame-retardant foam in peak condition.

Expert Pro-Tip: Modern 4-stroke airboxes are sensitive to dirt migration. When installing your No Toil cage, take a second to clean the airbox mounting flange with a light contact cleaner. Ensuring a perfect, grit-free surface for the filter's foam seal is the most important step in protecting your engine from premature wear.
