i need to buy new plugs and wires what do you guys suggest?


pinfield

 

I would use NGK plugs.As for wires I have used NGK's as well they are a good affordable wire.Magnacores are good but are more exspensive than the NGK's.

 

I was told to only put NGK plugs on that type of car by a "good" mazda mechanics

 

what is NGK an abrieviation for? and where would i get them from?

thanx

Not sure what NGK actually stands for (obviously Japanese), but they are readily available from Schucks or Napa.

 

I have part of an NGK box sitting in front of me. The katakana is; su pa ku pu ra gu (sparkplug) gu ri n (green). I really don't know what "green" is supposed to mean though. Nor do I even know what NGK means. Maybe Nippon (Nihon)? G? Kyokai?

 

I too don't know what it stands for.That is all I have ever heard that brand called though.I get my plugs at Advance Auto Parts.I got the NGK wires I had from Rotary Performance.

 

For the spark plugs, what core are you guys using? Copper, platium or iridium?
Also, what difference does hot, warm and cold rating plugs make?

Thanks

 

Well, it goes a bit like this: the hotter the plug, the better it'll work in low RPM and worse in high RPM, the colder the plug...you get the picture. "Hotter" plugs are for street/city/highway use, "colder" plugs are for spirited driving, and "cold" plugs are for racing, where the engine is constantly in high RPMs anyway....
As far as NGK plugs are concerned, BUR9EQ all around for TII is a good move. If you are heavily modified and plan on racing, then 11 (colder) is the "lowest" you should go. 11,5 and 13 are way too "cold" (will not work properly in low RPM, and will deteriorate rapidly).
Copper is the best conductive material of the three (has the lowest specific resistance), but lasts the least. Platinum is a bit sturdier, but way too expensive. Same goes for Iridium, although you might see some improvement with those...dunno
