Hello, I just purchased a 2012 Mazda5 and was going to do some basic maintenance to keep things fresh and know the dates parts were changed. I took out the spark plugs and noticed the ones I ordered (that said fit my vehicle) had more thread than the ones already in the car.
The ones in the car are azfs32fe. The ones I purchased are ltr5ahx (I know). AutoZone shows the azfs32fe as an alternative fit and the ltr5ahx as an exact fit (did the guy just buy the cheapest spark plugs at the time?). I got confused so I started looking for an engine code and found this...
It says L510573266. Do I have an L5 engine? Rockauto says I should have an L4. They're both 2.5L, yes? What spark plugs do I need?
