Review on Premium Guard PA6312 Filter Acura by David Alvarez

Strip normal airflow from the engine and get lousy performance. RDX is Turbo; It is very important to meet the airflow requirements. After replacing the turbo, the check engine light was on all the time. Read the Acura enthusiasts forum and the post says that changing the air filter solved the problem for them. Unfortunately that was the last thing on my radar. New filter + correct airflow = no check engine light and 3+ mpg more fuel. This is victory. Four stars for order fulfillment only. It took a few days to actually ship. This item wasn't on the main nave - and that's fine. If I was in a hurry, they were available at a local store for a slightly higher price.
