Fitting matched inlets on a 172 Phase 1

[chris blue]

Looking at doing this when the weather gets a tadge warmer

Understand its not the easiest of jobs with aircon on mine, the lower inlet anyway. Any gains with just fitting the top inlet, or would is mess the airflow and outcome in an uneven throttle?
Is a new lower inlet gasket needed?

Any hints? Or shall I just bail out and take to the local Clio Mech?

I was always under the impression that the lower is the one which will actually make a difference, especially if you dont already have an rs lower

do both or non. on their own they don't make much difference but work well with other mods.
