Acura 2014-2016 RLX V6 Gets K&N Replacement Air Filter and Performance Boost

Keeping Acura's flagship 2014, 2015, 2016 RLX luxury sedan on course for longevity and reliability is the K&N 33-5011 Replacement Air Filter, which fits precisely into the stock air filter box

The Acura RLX is the latest luxury sedan flagship of the Acura line that, when launched in 2013, was praised for its direct-injected, 310-hp V6 engine and an array of new technology as standard equipment. It beat a U.S. domestic sedan in early automotive media comparison drives, and for 2016 has received 19-inch rims, chassis & suspension upgrades for improved ride quality, and even more safety features.

In laboratory testing, following the ISO5011 air filtration protocol developed by the Society of Automotive Engineers, this filter in the RLX was rated with an air filtration efficiency of 98.25%

During development of the RLX in the post-2009 recession days, Honda executives said their thoughts had turned more toward producing premium vehicles incorporating advanced environmental technologies rather than cars with glamorous add-ons. This thought process produced a comfortable vehicle with more value than standout looks, but, combined with Acura's reputation for offering a lively ride, the RLX is leaving a noticeable wake for others to follow.

The course to enhancing the RLX's performance, value and longevity is to reduce air intake tract restriction without sacrificing engine protection with a K&N 33-5011 Replacement Air Filter. The K&N 33-5011 replacement air filter for the Acura RLX provides an enhanced blend of high airflow, filtration efficiency, and dust capacity to protect and keep the 3.5L V6 breathing effortlessly.

In laboratory testing, following the ISO5011 air filtration protocol developed by the Society of Automotive Engineers, this filter in the RLX was rated with an air filtration efficiency of 98.25% overall. As more air that flows through the filter, the more particulate matter it collects, and the air filtration efficiency improves. K&N air filters use an oiled cotton gauze filtration media. The airflow of a cotton air filter is superior to synthetic media and paper, but the use of oil means that filtration efficiency isn’t sacrificed.

K&N replacement air filters can be cleaned every 50,000 miles, or sooner depending on driving conditions, with a K&N Air Filter Cleaning Kit. Installing the 2014-2016 RLX V6 replacement K&N air filter, number 33-5011, is easy to do, reduces some of the costs of maintaining a luxury vehicle and gives owners an opportunity to do some of their own maintenance.
