Several automotive aftermarket exhaust systems provide the aggressive sound driving enthusiasts like as their cars or trucks accelerate from a stop or pull out to pass. Corsa made its name by inventing technology that provides such sound but that eliminates the annoying “drone” that persists after the car is up to speed or simply cruising along the highway.
And now, the nearly 25-year-old Berea, Ohio-based design, engineering and manufacturing firm is applying its airflow and acoustic expertise not only to the exhaust coming out of an engine but to the air entering that engine.
“We manipulate airflow and acoustics to meet performance requirements,” is how Craig Kohrs, vice president and general manager of Corsa Performance, explains the company’s new mission.
Corsa was founded in 1989 to do exhaust systems for boats. In 1998, it was asked to do an exhaust for the Chevrolet Corvette that would pace the Indianapolis 500 race and has been in the automotive aftermarket exhaust business ever since with its patented Reflective Sound Cancellation (RSC) technology.
Kohrs is part of the TMG Performance Products group that now owns Corsa. To enable the company to expand its portfolio and apply its airflow and acoustic expertise to more than exhaust systems, TMG recently purchased another renowned aftermarket supplier, Volant Performance, a Southern California-based producer of cool air intake systems. The deal also provides Corsa with a satellite sales and product-development base on the West Coast.
The first new product from the partnership is a Corsa Performance air intake for the 2009-13 Cadillac Escalade and its 6.2-liter V-8 engine. In early testing, Corsa reports a 20-horsepower increase as well as an improvement by 2 mpg in fuel economy.
Customers may experience a little more noise from their engines, said Corsa marketing manger Brent Noward, but “in a good way,” he said in an email exchange. “By drawing more air in and letting the engine breathe more, you may experience a more noticeable growl from your engine.”
The Corsa air intake includes a filter box designed to cool and maximize air volume, a performance filter using Donaldson PowerCore Filtration technology, and marine-grade silicone connector and an air duct designed to flow the cooled and filtered air into the engine.
The filter system “is the most revolutionary on the market,” Noward continued. “Manufactured by Donaldson to Volant's applications, this filter uses advanced technology for improved efficiency.
This material is a high-quality synthetic, that won't deteriorate as easily as traditional paper element and cotton/gauze filter media, while also providing vastly improved filtration up to 99.97 percent. In addition, it's water resistant and never needs oiling.
“PowerCore Filtration Technology,” he continued, “works by directing air into the front of the filter, where it is channeled into its fluted design. The channels are alternately sealed, allowing air to enter through an open flute and forcing it to exit out an adjacent flute. This allows the air to be filtered in one pass through the filter media with less restriction, allowing clean air to enter your engine for increased airflow and higher filtration efficiency.”
The air-filtration technology, he added, has a 4-year/100,000-mile warranty when used in urban conditions (as opposed to the dusty environment of off-pavement driving). The intake system hardware carries a one-year warranty.
And while it may be known as the Escalade intake, the new Corsa air intake system is designed to fit several trucks, sport utility vehicles and Jeeps. Corsa says installation should take less than 20 minutes.
Prices range from $349-$399.
The Escalade intake is available through Summit Racing Equipment, Jegs and other aftermarket retailers; see www.corsaperformance.com for a list of outlets.
