JDMSPEED Billet 72mm Throttle Body For K-Series K20 K24 PRB/PRC/RBC/RRC

72mm Billet Throttle Body for K-Series

This 72mm billet throttle body is a direct-fit performance upgrade for Honda K-Series engines and is commonly cross-referenced against PRB, PRC, RBC, and RRC intake manifold applications.

Overview

The JDMSPEED 72mm billet throttle body is designed for K-Series K20 and K24 engine builds that need more airflow than a factory unit can deliver. It replaces the stock throttle body on PRB, PRC, RBC, and RRC intake manifolds, making it a practical choice for naturally aspirated and forced induction setups. Enthusiasts building a K20 or K24 swap will find this throttle body sized to support higher horsepower goals.

Built For Performance

• 72mm bore size increases airflow compared to the factory throttle body
• Billet aluminum construction for strength and consistent bore geometry
• Compatible with PRB, PRC, RBC, and RRC intake manifold bolt patterns
• Designed for K-Series K20 and K24 engine platforms
• Direct replacement fit for the factory throttle body location

Fits These Machines

• for Honda K20 engines with PRB intake manifolds
• for Honda K20 engines with PRC intake manifolds
• for Honda K24 engines with RBC intake manifolds
• for Honda K24 engines with RRC intake manifolds

On-The-Job Use

• Naturally aspirated K-Series builds seeking more top-end airflow
• Turbocharged and supercharged K20 or K24 projects
• Engine swaps where the factory throttle body is undersized
• Intake manifold upgrades that require a larger throttle body opening

Specs At A Glance

Good To Know

Q: Will this throttle body fit my K20 or K24 swap? A: It is built for PRB, PRC, RBC, and RRC intake manifolds, so check your manifold type before ordering. Confirm the bolt pattern and sensor provisions match your specific setup.

Q: Do I need a tune after installing a 72mm throttle body? A: A larger throttle body changes airflow, so a retune is typically recommended to keep fueling and idle correct. Consult your tuner for the right calibration.

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