Weapon R Honda / Acura K20 Race Sheetmetal Intake Manifold - 501-122-112

What Owners Say

Owners and enthusiasts running the Weapon R intake manifold on high-performance builds consistently praise its flow improvements over restrictive OEM designs, with the plenum design eliminating factory hurdles that choke airflow. The manifold has proven itself on serious builds pushing 355+ whp, with users noting noticeable performance gains when paired with supporting modifications. However, experienced builders caution against using it as a budget option for extreme power goals like 800hp setups—the consensus is clear: if you're building for serious numbers, buy quality components the first time rather than skimping to save a few dollars. The Weapon R intake manifold has earned respect in the Evo community as a legitimate performance upgrade for street and track applications.
