Description
Eliminate the factory airflow restriction in your Yamaha FX-SHO FZR FZS VXR or VXS with the R&D Power Core Intake Manifold Sleeve. This billet venturi sleeve replaces the restrictive ribbon section in the stock manifold freeing up ~40 CFM of airflow for sharper low-end stronger mid-range and higher top-end RPM.
Core Performance Advantages
- Removes 40 CFM intake restriction with smooth venturi design
- Improves throttle response and acceleration right from idle
- Billet construction for maximum durability and precision
- Bolt-in sleeve – pairs perfectly with R&D intercooler spacer
Stock FX-SHO/FZR intake manifolds have a known bottleneck at the ribbon – this sleeve deletes it completely. Riders report 100+ RPM gains at top speed and much quicker hole shots making it a must-have before adding bigger supercharger wheels or turbos.
Quality & Real-World Gains
CNC-machined from aircraft-grade billet this sleeve is built to handle boost heat and vibration without flex or failure. It is the starting point for serious power builds on Gen3 Yamaha platforms.
- Unlocks true horsepower potential by relieving intake choke
- Noticeable power increase throughout the RPM band
- Essential before compressor upgrades or ECU tunes
- Complements R&D intercooler spacer for full CFM kit
More air = more power – this sleeve proves it. No other mod delivers such consistent measurable gains with zero downside.
Install & Build Advice
Remove stock ribbon press in R&D sleeve and reassemble. Professional install recommended for first-timers. Combine with intercooler spacer (612-18000 full kit) for 70-75 CFM total relief.
Start your FX-SHO/FZR power build right with the R&D Power Core Intake Sleeve.
