Ummm..yes! 4 of them
The Mazda 5 does not have glow plugs. Maybe you meant spark plugs?
There arent any. There arent any. There arent any.
the factory plugs gap is 0.028" - 0.032".
spark plugs for vehicles with electronic ignition come pre gapped when purchased .044
Change the spark plugs and wires... Change the spark plugs and wires...
if you cant find the spark plugs then you probably shouldn't be working on your car if you cant answer the question maybe you shouldnt leave answers like these
this could be valve stem seals or oil control ring,s
they should ALL be on top
I have had the best luck using NGK. Obtain proper plug number and gap from owners manual.
.044
Might want to check the secondary ignition system. That is everything from the coil(s) to the spark plugs.
