If you ever get a chance to see the two units side by side there is a differance! I was very impressed by the Billitflow Quality as I am a machinist by trade. I went to Billitflow to purchase the complete pulley set up. I left there with the throttle body and plenum also.
I also was able to overlook the complete design of both unit. I think the accufab is based on the cobra R design. Maybe a bit to much as the linkage is not properly aligned with the factory units tolerances and ports. The Billetflow is also a improvment on the cobra R t/b with the added feature of having proper linkage and port matching. And for the people who say that a t/b and plenum don't make a differance. It will and has proven itself already on the dyno. And who wouldn't want faster throttle response as a added mod?
