Description

The SiriMoto Big Bore Throttle Body Upgrade Kit offers a significant airflow improvement for performance-oriented vehicles. This kit centers around a brand new OEM Honda Drive-by-Wire (DBW) throttle body, featuring an impressive 80mm inlet diameter that tapers for optimized air velocity. By increasing the throttle body size, this upgrade aims to enhance engine breathing and potentially improve throttle response and overall performance. The kit includes the throttle body and any necessary adapters or hardware to facilitate a direct fitment where applicable. The product is noted to fit for factory intake manifolds. This upgrade kit is specifically designed for a range of Honda and Acura models, including various generations of the Honda Civic (8th, 9th, and 2012-2015 models specifically mentioned, including Si variants) and Acura TSX (1st Gen). It also supports the Honda S2000.
