GM LS EFI Thottle Body 95mm w/Tapered Bore

The Holley GM LS EFI Throttle Body 95mm with Tapered Bore is a precision fuel injection component engineered for LS-series engine builds requiring direct OEM fuel injection integration. This billet aluminum throttle body features a 95mm bore with tapered design geometry, delivering smooth throttle transition and optimized airflow control for factory LS engine management systems. The 4-bolt stock flange interface ensures seamless bolt-on compatibility with OEM LS manifolds and aftermarket LS intake manifold platforms without adapter requirements.

The tapered bore geometry reduces air turbulence at low throttle angles while accommodating peak airflow at wide-open throttle, a critical advantage for engine tuning precision. The 105mm single-blade design minimizes throttle lag and provides responsive fuel mapping feedback to the engine control unit. Black anodized finish protects the aluminum construction from corrosion and oxidation during extended engine operation, essential in high-heat engine bay environments. Weighing 3.51 lbs, this throttle body integrates with existing LS fuel rail and injector systems without supplementary harness modifications.

This component serves engine builders and tuners installing LS engines in custom automotive platforms, from truck swaps to full restorations. Users requiring direct fuel injection throttle control without carbureted adaptation will benefit from this direct OEM bolt-on approach. The 95mm bore size balances mid-range responsiveness with full-throttle capability, suited to street performance and street-strip applications where factory fuel management is desired. Buyers should verify intake manifold flange compatibility before purchase to confirm 4-bolt alignment with their specific LS platform.
