K&N TB-6621 Replacement Air Filter — Triumph Trident & Tiger Sport 660

Check your exact motorcycle. The following model/year combinations are listed for TB-6621. Similar model names, engine sizes or filter shapes do not establish compatibility. Model-year gaps are intentional.

Filter dimensions: 6.688 × 4.406 × 1.313 in. These describe the filter, not the shipping carton.

Compare the original filter, airbox opening and sealing surface before installation. Fit to the original airbox for the listed application; do not force the frame or leave a sealing gap. Follow the motorcycle service procedure and check that the airbox closes correctly.

This filter is supplied oiled. Use care products suitable for oiled cotton-gauze filters when servicing. Do not substitute foam-filter oil or install a filter that is damaged or incorrectly seated.
