More Details
This Big Bore Throttle Body Upgrade Kit is the easiest way to upgrade the throttle body on your Honda or Acura engine. The throttle body in this kit is a brand new OEM Honda DBW (Drive by Wire) Throttle Body, and the outside inlet diameter is a huge 80mm (3-1/8") that tapers down to 70mm at the throttle plate. The best part of all? This throttle body contains all the DBW components and is an easy bolt-on install. It also features high quality bolts and fittings, so the entire installation is just a simple "plug and play" bolt-on process.

Tuning Info: Since this throttle body allows more airflow than your stock throttle body, ADJUSTING THE ECU CALIBRATION AFTER INSTALLING THIS PART IS REQUIRED. Otherwise, your car may not drive correctly or get full power. WE INCLUDE A FREE CALIBRATION GUIDE FOR THE HONDATA FLASHPRO WITH EACH BIG BORE KIT.

Intake Fitment: Depending on the intake you use with this Big Bore Throttle Body, you may need to purchase a specialty silicone coupler that connects this throttle body to your intake. Please contact us for recommendations.

IMPORTANT INTAKE MANIFOLD FITMENT INFO: If using this product with a K20Z3 Skunk2 Pro Series or similar intake manifold, some clearancing near the manifold coolant port might be required. Applications labelled to work with RBC intake manifolds will work best if you are using a RBC, RRC, K20Z3 Skunk2 Pro Series (with clearancing near the manifold coolant port), or similar intake manifold. Skunk2 Ultra Series intake manifolds are not compatible with this product, nor is it compatible with 8th Gen Civic Si CT Engineering Supercharger Kits.
