The Twin Air PowerFlow Kit, part number 155800C, is designed to improve airbox sealing and filtration performance on select 2-stroke and 4-stroke off-road motorcycles. Manufactured by Twin Air, this complete air filter cage and sealing solution replaces the flimsy plastic stock cage with a rigid, lightweight billet aluminum cage that helps provide a more secure, leak-resistant fit inside the airbox.
For 2-stroke applications, the Twin Air PowerFlow Kit helps eliminate potential air leaks around the filter seal, allowing the air filter to perform as intended. For 4-stroke models, the kit replaces the restrictive stock backfire screen with a PowerFlow cage featuring a special backfire-resistant foam layer laminated to the inside of the filter. This design supports efficient airflow while maintaining added protection against backfire-related heat.
Fitment is model-specific, so verify compatibility with your motorcycle before ordering. The Twin Air PowerFlow Kit is supplied by the manufacturer under part number 155800C and may also be identified by vendor part number 715-5800C. It is a practical upgrade for riders seeking a more dependable airbox seal, durable filter support, and improved intake system performance.
