K&N High Flow Air Filter for Suzuki GSX 1300 BK B-KING - SU-1348

K&N High-Flow Air Filter | Suzuki GSX1300BK B-King (SU-1348)

Unleash the full potential of your hyper-naked with the SU-1348. Since the B-King shares its monstrous 1340cc heart with the Gen 2 Hayabusa, it requires a massive amount of air to produce its legendary torque. This filter is designed to replace the restrictive factory paper element, allowing the engine to breathe without compromise.

Key Features

• Massive Airflow for Hyper-Nakeds: Engineered to provide up to 50% more airflow than standard paper filters, ensuring the 1340cc inline-four stays responsive across the entire powerband.

   

• Exceptional Engine Protection: Built with K&N’s multi-layered oiled cotton gauze media, capturing up to 99% of harmful contaminants—critical for maintaining a high-performance engine.

• Washable & Reusable: This is a "Lifetime" filter. Instead of buying a new one every service, you simply wash, re-oil, and reinstall, making it the last air filter you'll ever buy for the B-King.

• Precision Fit: Specifically molded for the B-King’s unique airbox (which differs slightly from the Hayabusa setup) to ensure a perfect, airtight seal.

• Enhanced Performance Feel: Riders often report a more immediate throttle response and a deeper, more aggressive intake growl that matches the bike's "muscle" aesthetic.

Why Upgrade Your B-King?

The B-King is all about presence and raw power. The stock airbox is designed for extreme noise suppression, which can slightly dull the engine's "bite." The SU-1348 removes that bottleneck. It’s a favorite modification among B-King owners because it improves the bike's efficiency and sound without requiring expensive ECU tuning or mechanical changes.
