Moose Offroad P-BETA Precision Pre-Oiled Air Filter — 2015-2018 Beta RR RS 4T 2T

Moose Offroad — Precision Machine Oiling, Flame-Resistant Protection, and Maximum Horsepower

Take the mess and guesswork out of your maintenance routine with the Moose Offroad P-BETA Precision Pre-Oiled Air Filter. Designed specifically for the 2015-2018 Beta model range, this filter utilizes high-technology machine oiling to saturate the foam to perfection. By ensuring every pore is covered with zero excess oil, the P-BETA prevents "oil pooling" that can rob your engine of horsepower, while eliminating dangerous dry spots that allow engine-killing silt to pass through.

This professional-grade filter is pre-treated with high-tack, bio-friendly, and flame-resistant Super Seal Filter Oil. The flame-resistant properties are a critical safety feature for high-performance 4-stroke Beta models like the 350, 390, and 430 RR EFI, protecting against airbox fires caused by engine backfire. Delivered in a heavy-duty resealable bag, this filter stays fresh, tacky, and ready for an immediate swap—making it the essential spare for your race day gear bag or dual-sport adventure kit.

• Precision Machine Oiled: Guaranteed consistent oil saturation for optimal airflow and superior engine protection.
• High-Tack Flame Resistant Oil: Bio-friendly oil traps microscopic dust while providing an extra layer of backfire safety.
• Horsepower Optimized: Eliminates excess oil weight and restriction, allowing your Beta to breathe at maximum capacity.
• Resealable Storage Bag: Keeps the filter clean and ready for instant installation in the pits or on the trail.
• Made in the USA: Manufactured with high-quality foam and construction for long-term off-road durability.

Moto-House MX Pro Tip:

The 2015-2018 Beta airbox requires a precise fit to prevent dust bypass. When installing the P-BETA pre-oiled filter, wipe the airbox mounting surface completely clean of any old residue. Because this filter is machine-oiled to professional standards, you don't need to apply heavy rim grease, which can often drop into the intake. Simply seat the filter square on the cage and secure it. Always keep a spare P-BETA in its resealable bag—it's the fastest way to get back into the race when conditions turn dusty or wet.
