Best AC for M8
Hi
which is the "best" AC for our M8 engine ?
I know it is a stupid question... but I'm new in the HD world and I'm still collecting info on AC.
I live in Italy (not so great experience on M8) so I prefer to start from the US and then check if feasible in Italy (also in term of $$$, the prices are very very high).
Thanks a lot for ur support.

There you go. The stock one will flow all the air you need and then some. Been that way for years. I admit to changing a few but never for air flow reason.

It was a habit to change them did it just because I could until the 103 high out put and the M8 I no longer see a need to change them.
Even for a stage 1 exhaust the stock Ac flow is just fine.

Having done slip ons, AC, then tuner all separately I can say without a doubt the AC made the most improvement on my bike. Numerous dyno videos of the M8 on YouTube showing the AC as the best bang for the buck upgrade. It may be true that the stock AC is adequate but the dyno doesn't lie when it shows the most gains by adding a high flow AC on a stage one bike. Air flow aside, just the ridiculous size of the stock filter worried me, looks like a weed eater filter so not confident on how much dirt/dust that thing is catching after a few thousand miles. Agree or disagree but that is why I changed mine.
