I can only tell you that you've got the NGK standard and NGK standard extended correct.
Dunno on the others.

I was told by Mazda parts and service that I can only use nkg spark plugs in my car ...a Mazda protege LX 2003 2.0L.

Is that true, what if I buy the bosh?

And is it ok to use the $5.99 bosh plugs (with the 4 prongs that suppossedly do not have to be gapped).

Discount Auto said I could use the bosh in my car and that the $5.99 are the better than the cheaper bosh plugs and that I don't have to gap them. Is it true the 4 prongs by bosh do not have to be gapped?

Which is the way to go?

I tried BOSH , SPLITIFIRE , and NGK IRDIUM over the years I had my car and NGK V-groove is still the best.

BOSH, SPLITIFIRE very bad gas mileage, weird idle and easily carbon -up.

Our cars seem to only like stock like sparkplugs.

I am now experimenting with extended tip.

Ive used BOSCHE in my car its a 92 DX but i would think that it would be the same for most other proteges, ive never heard of only being able to use one type of spark plug before... :- \ wierd..

It's not true you can only use NGK spark plugs in your car. However, many Forum members, myself included, feel you can't beat the OEM copper plugs. The correct OEM plugs for your car are NGK BKR5E-11. Don't waste your money buying the Bosch and you don't need iridium plugs. If you buy the NGK's from your dealer or from www.sparkplugs.com, they will come correctly gapped: 1.0 -1.1 mm (.040" - 043").

goldstar is correct, don't waste your money on platinum or iridium plugs, they do nothing and can cause more harm than good. Stick to the NGK copper.
