Hey guys,
A few months back I asked what the part number is and then bought through the oakville mazda.
I never responded back but I thought I would in case someone else needs the part number.
This is for a 2006 mazda 3, but it's an aftermarket intake kit from 'mazdaspeed' not to be confused with mazdaspeed3.
The replacement filter part number is:
grms-8m-l10
With our special discount (what was it 20% or 25% on mazdaspeed parts?) it came to be 47.01$ after tax.
Hopefully this helps someone else didn't know where else to post it.
