Introducing the ASM ITB Kit, the ultimate upgrade for NSX enthusiasts seeking optimal airflow and performance with street-friendly usability. This kit is meticulously designed to provide superior flow and air-fuel ratio (AFR) across all RPM ranges, ensuring smooth operation whether you're cruising or pushing your NSX to its limits.
Unlike many other ITB kits, which suffer from inefficient injector placement that disrupts airflow and reduces fuel mixture efficiency (injecting "carburetor style" against the runner wall), the ASM ITB Kit features proper injector positioning. This design ensures more efficient fuel atomization and superior mixture control, especially at high airspeeds and RPMs, leading to better performance and smoother operation across all driving conditions.
Key Features:
- Optimized Flow & AFR: Designed for consistent airflow and AFR tuning in all conditions and RPM ranges.
- OEM Injector Compatibility: Utilizes OEM Honda injector placement and rails for hassle-free installation and compatibility.
- Optional High-Mount VTEC Injectors: Perfect for high-RPM performance, improving fuel delivery and mixture quality at peak power.
- Improved Low-RPM Fuel Trims: Designed to provide smooth idle characteristics and precise fuel trims, making the NSX more street-friendly, much like a BMW M car.
- Progressive throttle opening, the only NSX ITB kit that has a progressive opening ramp for the throttle inspired by the throttle opening sweep of the single cam C-Series engine, this aims to greatly improve tip-in and drive away easy (so the first inch of pedal travel opens the throttles significantly slower)
- Vacuum plenum, 8 port central plenum receives vacuum form all cylinders equally and has two outputs (FPR & MAP) and one feed port (IACV), 1 brake booster port is blank we recommend electric brake booster pumps
