Improved Performance

Built as a direct replacement for the stock air filter, the TB-8025 is designed to improve airflow while still delivering the engine protection K&N filters are known for. More airflow means your bike can breathe easier, helping unlock improved horsepower and torque without needing to dive into major modifications.

Like the rest of K&N’s motorcycle range, the new filter uses multiple layers of woven cotton gauze media for strong filtration performance. The pleated design also increases the filtration surface area, which helps extend service intervals and keeps maintenance straightforward.

OEM Fitment

Another nice touch is the application-specific sealing bead and base seal, designed specifically for the Triumph Trident 800 and Tiger Sport 800. Installation stays simple, and fitment is exactly as you’d expect from an OEM-style replacement.

Reusable

And because it’s a K&N filter, it’s fully washable and reusable too. The filter comes pre-oiled and ready to ride straight out of the box, so there’s no extra prep work needed before fitting it to your bike.

Limited Lifetime Warranty

The TB-8025 has an RRP of £62.49 + VAT (correct at time of publishing) and is manufactured in the USA, backed by K&N’s No-Hassle Lifetime Limited Warranty.

With the new generation of Triumph proving massively popular, this feels like one of the easiest upgrades riders can make. Its carefully designed to add a little extra performance while keeping servicing costs down over time.

The new TB-8025 filter is available to order now for the 2026 Triumph’ Trident 800 and 2025 Triumph Tiger Sport.
