Thanks Steve,
Just incase anyone comes down the same path as myself. I spoke with someone from RAM AIR and got this response to explain why its difficult to find any aftermarket intakes for the A4 CRTC Engine 3.0TDI.
Hi Will,
Thanks for messaging us,
I'm afraid I dont have any good news for you either. We currently do not have a vehicle specific induction kit for your A4.
I believe the MAF sensor is integrated in the standard airbox, which means this would need to be relocated away from the airbox, which is more complex than it sounds.
Best Regards,
