The Twin Air Pre-Oiled Air Filter is designed to provide reliable engine protection and consistent airflow for select Triumph motocross and off-road motorcycles. Part number 158383X features a dual-layer foam construction that helps capture airborne dirt, grime, and sand before they reach the engine. The filter arrives pre-oiled with Twin Air biodegradable foam filter oil, developed exclusively for Twin Air by Chevron Texaco.
Fitment: This Twin Air filter fits the 2024, 2025, and 2026 Triumph TF250X; the 2025 and 2026 Triumph TF450X; and the 2025 and 2026 Triumph TF450RC. It also fits the 2026 Triumph TF250C. Verify the motorcycle model and year before installation.
The coarse open-pore outer foam captures larger contaminants, while the fine open-pore inner foam traps smaller particles without restricting necessary air passage. Its durable adhesive is designed to withstand repeated cleaning, helping support long-term use and dependable maintenance intervals. The filter is manufactured slightly smaller than the stock-style filter to increase air space and circulation around the element.
Manufactured by Twin Air and supplied under vendor part number 158383X, this pre-oiled replacement air filter is a practical choice for riders who need dependable filtration in dusty, sandy, and demanding riding conditions. Follow the motorcycle manufacturer's installation and air-filter maintenance procedures for best results.
