K&N Launches New High-Flow Air Filter for Triumph 400 Models

Triumph’s modern 400 platform has quickly become one of the most talked-about additions to the motorcycle market, combining classic styling, lightweight handling, and everyday usability. Now, riders looking to unlock even more performance from their machine have a new upgrade option, thanks to the launch of the K&N TB-4024 High-Flow Replacement Air Filter.

Designed specifically for Triumph’s latest 400cc models, the TB-4024 offers improved airflow, enhanced engine protection, and the long-term reliability that K&N performance filters are known for worldwide.

Designed to Improve Performance

K&N has built its reputation on producing high-performance air filtration systems that deliver increased airflow without compromising filtration quality. The new TB-4024 continues that tradition by replacing the restrictive OEM paper filter with K&N’s signature high-flow cotton gauze design.

The increased airflow can help support:

• Improved throttle response
• Increased horsepower and torque
• Better engine breathing
• Enhanced riding performance across the rev range

Whether you use your Triumph 400 for daily commuting, weekend rides, or light adventure riding, upgrading the intake system is one of the simplest ways to improve overall ride feel.

Compatible Triumph Models

The K&N TB-4024 has been engineered specifically for the latest Triumph 400 platform, ensuring precise fitment and reliable sealing within the factory airbox.

Vehicle Compatibility

Because the filter installs directly into the OEM airbox, there are no permanent modifications required, making it an easy performance upgrade for riders wanting improved airflow without complex installation work.

Washable, Reusable & Built to Last

One of the biggest advantages of a K&N air filter is its reusable construction. Unlike disposable paper filters that require regular replacement, the TB-4024 can be cleaned, re-oiled, and reused for the life of the motorcycle.

The filter features:

• Multiple layers of woven cotton gauze filtration media
• Pleated construction for increased filtration area
• Long service intervals
• Pre-oiled design ready for installation
• Lifetime Limited Warranty

This not only reduces long-term maintenance costs but also makes the filter a more environmentally friendly alternative to disposable filters.

Performance Without Compromising Protection

Performance upgrades only matter if engine protection remains uncompromised. K&N’s layered cotton gauze media is designed to capture contaminants while still maintaining high airflow levels.

For riders using their Triumph Scrambler models on mixed terrain or dusty roads, maintaining effective filtration is essential. The TB-4024 aims to provide the ideal balance between airflow performance and dependable engine protection for both road and adventure use.

Manufactured with Proven K&N Heritage

K&N has been manufacturing performance filtration products in the USA for over 40 years, and the TB-4024 continues that long-standing heritage.

Backed by decades of engineering and global motorsport experience, the TB-4024 offers Triumph riders a trusted aftermarket upgrade from one of the world’s most recognised performance filtration brands.
