Took about 5-10 minutes to fit in all, and no insurance implications either.
I didn't notice any different induction noise but the car now runs smooter, and slightly more responsive.
When i compared the mazda OEM filter and this you can see how much more restricted the original filter is.
Maybe not essential but an improvement on the standard equipment.
