You are in the Mazda Protege
What is this discussion about?
Mazda Protege, Sedan
Mar 09, 2004 (7:07 am)
my first post on the subject (1997) was only to suggest the use of factory wires which work. They happen to be the same as the ones you now have (ngk). so you should be all set. MY suggestion that aftermarket cap and rotors can create problems for mazda ignition systems was a general observation and not directed toward vehicles without distributors.
As for what was corrected with the internals of the coil pack- I am not sure. Did you happen to need a warm-up converter shortly after replacing the coil? 9 out of 10 proteges with the bad coils had damaged converters as a result. Usually code p0421 would appear soon after.

They just replaced my coil and I kept on driving. Then again, as I said, I never had the coil go south on me -- so maybe Mazda did the recall pre-emptively.
By the way, you've just reached my car-detail knowledge limit. What the heck is a warmup converter?

Dang - you got the exact OEM NGK wires labelled 'Mazda", from another source! Good find You prolly did even better than my 20% off Mazda price!
Ray, the starts were smoother, and cold idle was quieter. This last part may be a placebo effect - but it seemed to rev quicker and smoother. Not having a tach made it harder to tell for sure
Mileage improved noticeably (1-2) and did not correspond to (was indep. of) weather or gas formulation changes. I did also change plugs at the same time, used OEM only.

... since my plug change, and I haven't replaced the wires yet (will do this afternoon) ...
You 5-speed 3rd-gen owners should be aware of the "quirk" where the Protege hesitates slightly when taking off in first sometimes? Well, upon this latest plug change, it seems to have disappeared or, at least, greatly diminished. Wondering if Mazda's using different plugs or a different gap now? I dunno. Maybe just the new plugs with their associated clean spark are diminishing this, but I've noticed in the last few days that the car is much smoother taking off in first.
Can't wait to see what the wires do ... and wow Ashu, looks like I've made the find, huh? I know the wires are NGK ZX52s, with an NGK stock number of 8198. As for the blue color, the following link DOES NOT show the exact wires, but shows a set of NGKs that illustrate the color:

just because I'd think I'm supposed to notice.
#2043 of 3742 warm-up converter
Mar 09, 2004 (8:19 am)
mazda has many names for it's parts-pre-converter, warm-up converter, three way warm up converter....basically I am referring to the pre cat. This is the one directly following the exhaust manifold. There is another converter mounted horizontally below the car.

are what mazda uses as oem replacement.........saving $30 on a set is definitely a plus.
#2046 of 3742 Well, to play devil's advocate ...
Mar 09, 2004 (8:40 am)
Anyone can color their wires blue. Are we certain that these are the EXACT wires as OEM? Is there an NGK model or stock number on Mazda's wires?
If I'm reading you correctly, Mazda uses a DIFFERENT wire than what was installed at the factory as a replacement, right? (My stock wires are black.) If they're using a different wire, I wonder why?
Beating this subject to death,
#2047 of 3742 One more thing ...

I'm doing all this pre-emptive maintenance this week because I'm leaving town Friday on a 5-hour trip to Charlotte, NC, and my return trip won't be the same route as I've got a stop to make in southwest Virginia near Mount Rogers. So I'll be traveling somewhere around 700 miles on the new plugs, wires, oil and coolant, and rotated tires, on everything from smooth interstates in the lower elevations to back roads (even a gravel road) in some of the highest elevations in Virginia (up to about 5,500 feet). I'll have a full report -- including gas mileage numbers, which ought to interest EVERYONE who's read the news lately -- upon my return next Tuesday.
