The J's Racing BSA-S1 is a 65Φ SPL Big Throttle body, constructed from FRP, designed to enhance the performance of the HONDA S2000 AP1 equipped with the F20C engine. This upgrade increases the butterfly caliber from the standard 62.5φ to 65φ, resulting in an approximate 8% increase in the inflow air area. This big throttle body is suitable for a wide range of applications, from lightly tuned vehicles requiring inspection compliance to more aggressively modified track cars. The product is compatible with all specifications, and users can expect to experience increased power and torque even with a stock muffler. The intake caliber measures 70Φ. This is an original modification item. Customers must send their genuine throttle body to J's Racing for processing. It is specifically designed for AP1-100, 110, 120, 130, and 135 models, as well as AP1-200. It cannot be installed on AP2 models, which utilize a drive-by-wire system.
