Q: Reverse manifold TSUNAMISTI 26 days ago
I previously asked a question about using your ams manifold in the reverse position, I know the ams reverse manifold doesn't have an upward angle to clear my alternator but the other model appears to have an upward angle that I need to clear the alternator. Any thoughts on fitment? Thank you

A: The reverse rotation intake manifold requires an alternator relocation and A/C delete, it is not a direct bolt in and requires modifications. Trying to modify the standard intake manifold in to a reverse mount would also require modification. We have not done any fitment testing.

Q: Reverse manifold fitment TSUNAMISTI 2 months ago
I currently run the stock subaru sti manifold reversed with the alternator in its lowest location and with a 19mm spacer under the manifold. The stock manifold throttle body is angled upwards allowing it to clear the alternator. Does your reverse manifold throttle body inlet have a similar upward angle? 2013 subaru wrx sti. Thank you
