The Twin Air Powerflow Throttle Body & Airbox Kit is a premier intake performance upgrade engineered to replace restrictive OEM air filter cages, fragile backfire screens, and narrow intake boots with an unrestricted, maximum-airflow induction system. Modern four-stroke dirt bikes feature a restrictive wire mesh backfire screen built into the stock plastic filter cage to prevent intake flame backfires from igniting the filter. However, this dense wire screen creates severe airflow drag, reducing air velocity and choking throttle response.
The Twin Air Powerflow Kit solves this restriction by replacing the stock plastic cage and screen with a rigid, CNC-machined 6061-T6 billet aluminum cage and an oversized backfire-resistant dual-stage air filter. The filter features a specialized inner layer of flame-retardant foam that safely dissipates backfire sparks without requiring a restrictive metal screen. The precision-machined aluminum cage eliminates plastic flex, ensuring a perfectly flat, leak-proof seal against the airbox flange. The kit includes a rigid aluminum mounting bracket and an oversized aluminum mounting pin that locks the filter securely in place, delivering up to a 10-15% increase in intake air volume and crisp throttle snap off idle.
- Cage Material: CNC-machined 6061-T6 billet aluminum with hard-anodized finish
- Filter Foam: Custom dual-stage foam with laminated flame-retardant inner barrier
- Airflow Gain: Up to 10-15% increase in intake air velocity and volume
- Mounting Pin: Oversized threaded billet aluminum filter holding pin
- Sealing Flange: Rigid aluminum rim eliminates cage deformation and bypass leaks
### Step-by-Step Installation & Safety Protocols Installation requires removing the seat and factory air filter. Unbolt the stock filter cage and remove the OEM wire backfire screen if separate. Clean the airbox intake boot thoroughly of any dust using a lint-free towel. Install the Twin Air billet aluminum sealing flange (if model requires it) and secure the aluminum mounting hardware. Oil the supplied flame-resistant Powerflow dual-stage filter with quality foam filter oil, mount the filter onto the rigid aluminum Powerflow cage, and insert the assembly into the airbox. Thread the aluminum retaining pin and tighten snugly, verifying that the thick foam base forms a continuous airtight seal around the entire airbox perimeter.
### Maintenance & Filter Servicing Maintenance involves servicing the flame-resistant filter with dedicated foam filter cleaner and re-oiling with foam filter oil before every moto.
Frequently Asked Questions
Q: Is it safe to eliminate the metal backfire screen?
A: Yes, because the Twin Air Powerflow kit includes a specially formulated dual-stage filter with an integrated flame-retardant inner foam layer that prevents backfire sparks from igniting the filter without needing a restrictive wire mesh.
Q: What performance improvement will I feel with the Powerflow Kit?
A: Riders experience noticeably sharper throttle response, faster engine revving through the mid-range, and improved top-end airflow that allows the engine to pull harder down long straights.
Q: Can I use standard Twin Air replacement filters with the Powerflow cage?
A: No. You must use Twin Air Powerflow replacement filters specifically designed with the oversized profile and flame-retardant foam to fit the Powerflow aluminum cage.
Q: Does eliminating the screen require ECU re-mapping?
A: Most modern EFI motorcycles adapt automatically to the increased airflow, though custom dyno mapping optimizes the full power potential of the kit.
