Show original supplier description
The J's Racing 65Φ SPL BIG THROTTLE is a performance upgrade designed to enhance airflow for the Honda Integra DC2 DB8 models equipped with the B18C engine. By increasing the butterfly caliber from the stock 62.5mm to 65mm, this throttle body expands the inflow air area by approximately 8.2%, contributing to noticeable increases in both power and torque across the entire RPM range. Constructed from FRP (Fiber Reinforced Polymer), this throttle body is built for durability and performance. The larger 65mm butterfly caliber and 70mm intake caliber allow for greater air volume, directly translating to improved engine response and overall performance, suitable for both street driving and track use. Installation requires the trade-in of the normal throttle body, as the unit will be processed in-kind. Customers must send their existing throttle to J's Racing for modification.
