where did you get them from?

 

The plugs and coils were from http://www.finishlineperformance.com/ and the rear O2 sensor was from Mazsport on Ebay.

 

nice, thats the cheapest dealership i have seen

 

+1 Thanks for the pic's - i was just looking into finding a thread that had pic's of coil replacements -

 

the problem that i get into when i tried checking my coils, is that large wire that is by or below the nuts that hold on the coils, that and the throttle body

 

Joe (R.P.M.) used a 1/4" drive set with an extension (4") and pushed the wire just out of the way.

Joe pulled off the intake rubber piece and then we pulled the air box out of the way.

It's a good idea to pull the plug wire before unbolting the coil.

 

cool, and the nuts are 10 mm right?

 

ya they are 10 mm nuts. just use a long extension and kinda push the harness out of the way, its only in the way of the 1 coil the rest are eay. i just checked mine and looks like i will be needing new coils too .

 

im gonna try checking mine tomorrow

 

I got 6 OEM plugs from online site for about 10 bux each, Yep OEM, Brand new, with Mazda name on it.

2 Hotter 6 plug, 4 OEM 7 stock range plug

Too bad they dont have trailing plugs for sale

Im gonna replace mine as soon as the weather gets around 60 degrees, for your reference is 28 degrees this morning, and now its 38 @ 10pm
