70mm Throttle Body New Fit K-Series K20 K24 RBC/RRC/PRB/PRC Dual bolt pattern

70mm Throttle Body for K-Series K20 K24

This 70mm throttle body is a bolt-on intake component intended for K-Series K20 and K24 engine builds, featuring a dual bolt pattern that fits RBC, RRC, PRB, and PRC intake manifolds.

Overview

This 70mm throttle body is made for K-Series K20 and K24 engine setups where a larger throttle bore is needed over the factory unit. The dual bolt pattern lets it mount to RBC, RRC, PRB, and PRC style intake manifolds without an adapter. It suits engine swap builders and tuners assembling or refreshing a K-series intake system.

Built For Performance

• 70mm throttle bore for increased airflow over the stock throttle body
• Dual bolt pattern fits RBC, RRC, PRB, and PRC manifolds
• Aluminum body construction
• Throttle plate and shaft assembled for direct cable or linkage hookup
• Mounting flange machined for a clean gasket seal

Fits These Machines

• for Honda K20 engines
• for Honda K24 engines
• Manifolds: RBC, RRC, PRB, PRC

On-The-Job Use

• K-series swap builds needing a larger throttle bore
• Naturally aspirated builds chasing better top-end airflow
• Replacing a worn or damaged factory throttle body
• Intake manifold changes using RBC, RRC, PRB, or PRC flanges

Good To Know

Q: Will this bolt directly to my stock manifold? A: It fits manifolds with the RBC, RRC, PRB, or PRC bolt pattern, so check your manifold flange before ordering. Some setups may need a matching gasket and a tune afterward.

Q: Do I need a reflash after installing it? A: A larger throttle body changes airflow, so a tune or reflash is commonly recommended to keep fueling correct. Confirm your ECU and intake setup are compatible with the change.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
