50K Maintenance?
 

I am at 45k maintenance without an owners manual.

I was wondering what people would recommend doing to the car at this point.

I have a feeling I need a new set of plugs, and based on the reading I should get 4 NKG plugs for 20 bucks a pop.

I thought I remember the dealership telling me about plugs+wires etc. but I dont want to throw my money any more than I have to (I already give them 35$ to change my oil, just cuse I am too lazy)

What are everyones thoughts?

new air filter? Tranny fluid change?

I am sure their is a sticky somewhere about the different maintenance mazda does at X amount of miles. It sounds like you are spot on though on what you need to do.

Here are some things to consider that come to mind plugs, coils, tranny & diff change, air filter, pollen filter.

Here's the recommended maintenance schedule from Mazda. It's in the back of the owners manual.
