NASHVILLE, Tenn., April 16, 2026 (GLOBE NEWSWIRE) — Cataclean®, the trusted brand in fuel and exhaust system cleaning solutions, in the Holley Performance Brands (NYSE: HLLY) portfolio, today announced the launch of Cataclean® Diesel Exhaust System & DPF Cleaner, a new diesel-specific emissions system treatment that expands the Cataclean line into a new vehicle segment, bringing the brand to diesel truck owners, commercial vehicle operators and other diesel drivers seeking solutions to help restore emissions system performance and efficiency, while also supporting Holley’s American Performance chemicals expansion strategy.
Cataclean Diesel Exhaust System & DPF Cleaner is designed to benefit diesel engines and reflects an important customer insight: diesel vehicle owners often prefer diesel-specific formulations over multi-fuel additives when addressing emissions-related issues. The product is engineered to help clean critical diesel exhaust and fuel system components, including the diesel particulate filter (DPF), catalytic converter, turbocharger, oxygen sensors, injectors and cylinder heads, helping support system regeneration, fuel economy and overall performance.
“Cataclean is one of the strongest and most recognized brands in our chemicals portfolio, and this launch extends that brand into an attractive new market,” said Nick Hite, SVP American Performance, Holley Performance Brands. “Cataclean Diesel Exhaust System & DPF Cleaner gives diesel customers a solution designed specifically for their vehicles, while supporting our broader American Performance chemicals expansion strategy with a product that fits naturally into a large category with recurring maintenance demand and strong retail relevance.”
Cataclean Diesel Exhaust System & DPF Cleaner is a lab-tested formula engineered for today’s emissions-challenged diesel vehicles. In controlled testing conditions, the product demonstrated up to 25% improvement in DPF performance and up to 50% reduction in hydrocarbons. Results may vary by vehicle condition, mileage and emissions system health.
The launch builds on Holley’s broader expansion of its automotive chemicals portfolio, which includes which includes NOS Octane Booster, Holley Carburetor Cleaner and Baer Spray Brake Cleaner.
