Hi Taffmog,

A few concerns about that particular design for our M3W.

Morgan does not offer an ECU remap for their stage one which includes the higher flow exhausts and an S&S Stealth air filter like the one I have so they apparently feel the existing stock ECU can properly adapt to the new airflow into the engine using these designs. And in fact the engine runs fine with the Morgan Aero Racing stage one without an ECU remap, I can attest to that. If the double air filter allows much more air in and the ECU can't adapt properly then the air/fuel mixture will be leaner raising your cylinder temperature. So the double design is alittle bit of an unknown for the M3W unless someone you know has experience with it on a M3W. Obviously someone installed one so you can ask them about their experience with it.

Also the bottom air filter looks like it could be obstructing the airflow over the right cylinder asymmetrically raising the right cylinder temp.

The double design does look nice though.

When I installed my Morgan Aero Racing stage one I purchased the exhausts separately from the air filter but kept the air filter design the same as offered by Morgan because of the concerns above.
