do any of you know the diameter of the 05 mazda6s throttle body size? is it 100 mm or no?

 

Inner diameter is 65 mm, outer is 70 mm.

 

thank you very much, I think it will be a wise investment to purchase a bigger throttle body than. that will be a great step towards obtaining plenty of air flow to the engine.

 

I would think that the volume of air has been restricted by that point. If you're using a stock intake, the air volume that comes in will simply be a constant, and the only thing that might increase it would be a more open airflow into the throttle body, WITH a larger throttle body capable of increased airflow.

Correct me if I'm wrong, but your intake is only a diameter of x.xx cm, which would only be able to support xx.xx cfm of air being pushed through it volume wise, especially when you have an airflow meter to tell the ECU what your vehicle is doing. This is assuming a naturally aspirated engine (turbos compress the air...).

 

i'm getting a MAFci cold air intake.... but i'm trying to get as much out of my ride as i can right now with that intake. next step will be headers followed by a custom exhaust once i find one that is suitable for me. not a big ricey-sound kind of guy.... right now making the engine sound beefy will suffice me for now.
