Intake Manifold and 70mm Throttle Body for Honda

This D-Series intake manifold with 70mm throttle body is a direct-fit air delivery assembly for Honda Civic, CRX, and Del Sol models running D15 and D16 engines.

Overview

This D-Series intake manifold and 70mm throttle body combination replaces the restrictive factory air path on single-cam Honda engines. It routes intake air evenly to each cylinder while the larger 70mm throttle body feeds more volume at wide-open throttle. It suits Civic, CRX, and Del Sol owners running D15 or D16 engines who want a bolt-on intake upgrade for street or track use.

  • Cast aluminum intake manifold with smooth internal runners for consistent airflow
  • 70mm throttle body bore sized for improved throttle response over stock
  • Direct-fit flange pattern for D-series cylinder heads

  • for Honda Del Sol with D15 or D16 engine

On-The-Job Use

  • Del Sol builds refreshed during engine maintenance
  • Track and autocross cars running naturally aspirated D-series setups
  • Garage installs replacing a cracked or leaking factory manifold

Good To Know

Q: Will this bolt to my stock D-series head? A: It is designed to match the D15 and D16 intake flange pattern, so it mounts using the factory bolt locations on these heads. Verify your specific engine code before ordering.

Q: Do I need a tune after installing? A: An intake manifold and throttle body change can alter airflow, so a tune or engine management adjustment is advised for best results and safe fueling.

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