BLOX Racing BXIM-00202-SI-V2 70mm Throttle Body V2 Silver Honda B/D/F/H-Series

Vehicle Fitment

• Honda B-Series engines: B16A, B16A2, B16A3, B17A1, B18A1, B18B1, B18C, B18C1, B18C5, B20B, B20Z - found in Honda Civic, CRX, Del Sol, Integra, and B-Series engine swap applications
• Honda D-Series engines: D15B, D16Y, D16Z, D16A - found in Honda Civic, CRX, Del Sol, and D-Series applications
• Honda H-Series engines: H22A, H22A1, H22A4, H23A1 - found in Honda Prelude, Accord, and H-Series swap applications
• Honda F-Series engines: F20B, F22A, F22B - certain F-Series Accord engines only; verify compatibility with your specific intake manifold before ordering

Fitment Notes

• Cable throttle (drive-by-cable) only - not compatible with drive-by-wire (electronic throttle) systems
• Cross-platform fitment covers Honda B, D, H, and certain F-Series Accord engines sharing the same throttle body bolt pattern and cable actuator style
• Not compatible with Honda K-Series engines - a separate BLOX Racing throttle body is available for K-Series applications
• Not CARB legal - not for sale or use in California; intended for off-road/track or non-emissions-controlled use only
• This listing is specific to the 70mm bore size, Silver anodized finish; 72mm, 74mm, and 76mm bore sizes are available separately
• IAC port included - reuses OEM idle air control hardware; no additional adapter required
• TPS sensor included - no need to source a separate throttle position sensor for installation

Features

• Precision CNC machined from AL6061 billet aluminum for superior dimensional accuracy, strength, and a clean machined finish compared to cast OEM units
• 70mm enlarged bore diameter increases incoming airflow volume over the OEM throttle body, delivering a sharper throttle response and supporting additional horsepower and torque gains when paired with a matched intake manifold and camshaft setup
• Silver anodized finish provides a durable, corrosion-resistant surface with a clean, show-quality appearance
• Laser-etched BLOX Racing logo and bore size on the throttle plate for product identification and authenticity verification
• Brass throttle plate for smoother operation, improved sealing at idle, and better long-term durability versus OEM plastic or aluminum plates
• Sealed bearings on the throttle shaft deliver a precise, consistent pedal feel with reduced friction and play over the service life of the part
• Stiffer throttle return springs provide crisper pedal actuation and a more direct, responsive throttle feel
• IAC port included for reuse of the factory idle air control valve - maintains proper idle characteristics without modification
• Provisions for adjusting idle air and throttle plate stop position - allows fine-tuning of idle and base throttle settings during installation

Product Description

The BLOX Racing BXIM-00202-SI-V2 is the V2 iteration of BLOX Racing's widely used billet throttle body for Honda B, D, H, and select F-Series cable throttle engines. Precision CNC machined from AL6061 billet aluminum, this 70mm throttle body is engineered to replace the factory unit directly while delivering a meaningful increase in airflow capacity. The enlarged 70mm bore diameter over the stock throttle body allows greater air volume to enter the intake manifold under both part-throttle and wide-open-throttle conditions, producing a noticeably sharper throttle response and supporting horsepower and torque gains when combined with a compatible intake manifold and performance camshaft profile. The silver anodized finish is durable and corrosion resistant, and the laser-etched BLOX Racing logo with bore size marking on the throttle plate adds both authenticity and a clean aesthetic.

The V2 design retains the core strengths of the original while refining key mechanical details. Sealed bearings on the throttle shaft eliminate the slop and inconsistency that develops in worn OEM units, while the brass throttle plate provides a tighter, more consistent seal at idle and improved longevity over stock. Stiffer throttle return springs contribute to the crisper, more direct pedal feel that defines this throttle body's reputation among Honda engine builders. The IAC port is preserved for seamless integration with the OEM idle air control system, and provisions for adjusting both the idle air bypass and throttle plate stop position allow tuners to set a proper base idle during installation. A TPS sensor is included, and all necessary mounting hardware ships with the unit - making this a complete, bolt-on upgrade for any B, D, H, or compatible F-Series cable throttle application.
