A4 bolt on iR3

[Andre]

do anyone know if it will be possible to run a A4 bolt/speed bolt in my iR3. i know it will fit, but will i see drop off or lower efficency since its got larger air passages, thats what i`m wondering about?

Thanks...

No you shouldn't have a problem. If anything you'll be able to lower your minireg pressure a bit. Same idea as when switching from the stock bolt to any of the aftermarket ones (Cobra, R-11, New designz, etc..). The single inlet on the bolt is more efficent than the open design of the stock one.
