Katech Ported Stock 87mm Throttle Body. I bought this used from a member here and it also has 12k miles on it. Worked perfect, required no tuning to function when I initially installed it.

This TB with standard RF intake, Kooks 2" headers and E85 (65% E blend) made 637RWHP/645RWTQ with a BRC tune. I went to a Kong X port, 103mm TB and Big Gulp.

TB - $225 shipped to CONUS
