Increased Performance with e-dialog: BAR-TEK® Boosts Revenue by 44 Percent
German Engine Tuning Webshop Leverages Digital Campaigns by e-dialog
The leading online shop for engine tuning parts in the German-speaking region, BAR-TEK®, significantly increased its performance in the past fiscal year: In fiscal year 2025, the company generated 44 percent more revenue than in the previous year. The driving force behind this success is the data-driven campaigns by the digital agency e-dialog: These achieved a Return on Ad Spend (ROAS) of 619% with Meta and Google Ads over a period of twelve months.
Content from the CEO Personally
“Power is created where precision meets passion. Together with e-dialog, we have put our growth into high gear,” explains Bartek Bartoszewicz, founder of BAR-TEK®. The engine technician with ten years of Formula 1 experience not only acts as CEO but also appears in front of the camera himself. On his own YouTube channel and an Instagram account with over 42,000 followers, he personally inspires motorsport fans for products, some of which he developed himself.
Full Performance on Google and Meta
On the same channels, e-dialog’s campaigns target the motorsport audience. The informative video content is complemented by dynamic ads on Meta, which are linked to BAR-TEK®’s product catalog. In addition, effective campaign formats on Google Ads such as DemandGen and Performance Max are utilized. A robust tracking concept ensures the campaign’s success is measurable at all times.

Our goal was to get the maximum performance out of the available budget. This requires a well-thought-out strategy, a smart mix of channels and formats, and continuous optimization. And, of course, a close, trusting collaboration with the client.”
BAR-TEK® and e-dialog will continue their collaboration in the coming fiscal year and are preparing for another revenue peak around Black Friday.
