Weapon R Intake Manifold Description
This is the revised version of the R18 intake manifold, with longer runners to provide more torque!
The 2006-2011 Civic DX/LX/EX (R18 motor) has a very restrictive intake manifold from the factory. This new Weapon R intake manifold intake is 40% larger than your OEM one and will significantly increase airflow. For turbocharged R18 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.
Please note that Weapon R is no longer including the "Fuel ECU" device because they have found it is not needed for this product to work correctly.
Key Features:
About a 10-12 whp gain, depending on modifications. Turbocharged R18 Civics will see even larger gains.
40% larger than stock!
Made from billet AL6061 aluminum to provide a great combination of strength and weight savings.
Bolt-on installation and works with all OEM sensors.
Comes with installation hardware and instructions.
