Most Honda Civics have a very restrictive intake manifold from the factory. This Weapon R intake manifold flows up to 40% more air than your OEM one and will significantly decrease airflow restrictions. For turbocharged Honda Civic owners, this intake manifold is just about the best add-on you can get!
This intake manifold features CNC velocity stacks, CNC machined flanges, and is made in-house to ensure top quality. In addition, the manifold is made from AL6061 aluminum and is very lightweight. It is also tested for leaks and pinholes to ensure all customers get optimal power gains. Best of all, it comes with ports for all OEM sensors and is a bolt-on installation.
