Introducing the long-awaited R9K 1AR / 2AR Billet Intake Manifold, a true game-changer for the AR platform!
After extensive dyno testing and valuable input from multiple test owners, this intake manifold takes everything that made stock setups limited and transforms it, delivering sharper throttle response, optimized high-RPM flow, and proven gains of up to 15 WHP, making it track-ready while still reliable for daily driving.
Key Features
✅️ Redesigned plenum geometry for improved mid-to-high RPM flow while maintaining strong low-end torque.
✅️ Integrated o-ring seals between the runners and plenum for a perfect, leak-free fit, no messy sealant or paper gaskets.
✅️ Optimized runner taper and length tuned for both naturally aspirated and forced induction builds.
✅️ Vacuum and PCV ports relocated for a cleaner engine bay and easier installation.
✅️ Optional throttle body adapter supports OEM electronic throttles and large-bore upgrades up to 82mm.
✅️ Machined from aerospace-grade 6061 aluminum, hard anodized black for maximum durability and heat resistance.
✅️ Dyno-proven gains of up to +15 WHP with only minor supporting modifications; exhaust and tune recommended.
All the innovation, precision, and reliability you expect, now available for the 2AR-FE.
