PeakActivity helped K&N Filtration recover from a 50% drop in sales caused by a flawed site redesign and restore long-term growth.

K&N Filtration is a global manufacturer of performance air filters and automotive products with a catalog of over 12,000 parts.

The Challenge

Following a website redesign, the direct-to-consumer business saw an immediate 50% decline in sales.

Customers were unable to complete purchases due to issues in the user experience. The path to purchase had become unclear, and critical functionality no longer supported how customers navigated the site.

What had been a high-performing channel quickly became a source of risk for the business.

The Solution

PeakActivity moved quickly to identify the exact points where the experience was breaking down.

The focus was on simplifying the path to purchase and restoring stability to the platform. This meant removing friction, clarifying navigation, and ensuring that customers could easily find and complete what they came to do.

The team prioritized speed without sacrificing quality, relaunching the experience in under four months.

The Impact

The buying experience became clear and predictable again.

Customers could move through the site without confusion, and the barriers that had been blocking conversion were removed.

The business regained confidence in its digital channel as performance stabilized and then began to improve.

What This Enabled

K&N Filtration now operates a high-performing DTC channel that supports long-term growth.

The business replaced a failing experience with a stable, scalable foundation that continues to drive results.
