Skunk2 Pro Series 74mm Billet Throttle Body – Honda/Acura D / B / H / F Series | Race Only

Maximize airflow on your Honda or Acura B, D, H, or F series build with the Skunk2 Pro Series 74mm Throttle Body. CNC-machined from forged 6061-T6 billet aluminum and hard anodized in Skunk2's signature finish, the Pro Series TB delivers significant horsepower gains throughout the powerband on heavily modified naturally aspirated applications and even greater gains on forced induction builds. Compatible with Skunk2 Pro Series intake manifolds as well as OEM and other aftermarket manifolds — making it one of the most versatile large-bore throttle body options for the Honda platform.

Race Only — not emissions compliant for street use.

Key Features

• 74mm Bore: Large 74mm bore maximizes airflow for modified B, D, H, and F series engines with high airflow demands on both NA and forced induction applications
• Forged 6061-T6 Billet Aluminum: CNC-machined from forged billet aluminum using CAE (Computer Aided Engineering) design tools for superior flow and durability
• Relocated MAP Sensor: Unique design relocates the MAP sensor underneath the throttle body for cooler sensor operation and a cleaner engine bay appearance
• OEM Water Passages Eliminated: Factory water passages removed for cooler throttle body operation and a cleaner, more purposeful underhood look
