noticed ..on stock air box
 

I noticed on the stock air filter box that there was..N326...now I know that corresponds usually to the ECU..is it there for fast reference,actual part number ,or is it just coincidence.. head scratcher for the day..too cold for fixin stuff..

N326 N327 etc. appears on nmany Mazda parts

eg. Spigot (pilot) bearing (man. box)'74 on mazda N326-11-D03K-99

Mazda Rx7 86-88 N326 Fuel Pump

1986-88 Mazda RX7 RX-7 N327 Boost Sensor

I never noticed that before, Ive got one sitting next to me that i have up for auction. And I had to go see for my self. Sure thing n326. was yours from a TII as well?

Maybe if we can get someone with a N/A we can figure it out. I would assume that the air-boxes are the same. Hmmm

its just a part number, part of the mazda product code. :)

The N326/N327/N332/N318 etc are engineline numbers corresponding to the emissions and engine assembly that is used.

But it is not uncommon to have a N332 engine assembly use a N326 P/N air cleaner.
