    Stage 3 is kind of a joke imho. I feel stage 3 should be stage 1.5. It is not the same as different stages on other cars. The last car I was working on, the stage 3 was a complete upgrade with exhaust manifold, turbo, wastegate, steel braided lines, etc.

    Fixing imperfections in the manufacturers design shouldnt be considered stages but maybe one or 1.5 stages. (FMIC, intake, exhaust, etc)

    This isn't a thread about your opinions on the stages.

    Are you a FiST owner? If so, start buyin' or continue cryin'...you don't think Ford was gonna build you a razecar, did you? The last time that happened, Ford built 200 road legal versions of a Group B rally car to comply with FIA homologation regulations...now give me RS200 plz!

    You're right. I was indicating that the logic behind changing plugs for the small increase in power you are getting with a marginal(none?) increase in boost is quite hilarious. Why in gods name would you need to change plugs for the most basic of upgrades? If you used the search button you would see the only people talking about changing plugs were the ones going to a "colder" plug which in itself is comical but I guess personal preference.
    I assumed you meant stage 3 "tune" which is literally a tune of stock parts with other parts that their only function is increasing airflow into and out of the motor. More air means different plugs? Maybe if it was more boost....
    Besides increasing flow into and out of the motor with a tune that utilizes the stock parts I dont see any mods out that would require different plugs except for the upgraded turbo.

    I guess my assumption is that smart people learn what the function of parts are before giving away their money to waste on new ones and that some people would actually research things before posting questions that the answer is easily found for.

    I WAS asking for a colder plug. And if its fo the most basic upgrades, then how do you explain the ford racing kit for the focus st? Just a tuner and colder plugs. Instant +90 torque. They wouldn't add the colder plugs for fun

    My mistake, I thought you were inquiring about a fiesta. Carry on.

    But, a quick search on google you would find a thread on a different forum that shows viable options for a colder plug. Just saying. I guess I just am used to people doing research before posting questions. Residual left over from another forum.

    Different engine, different requirements.

    Those have been proven to not fit and are causing issues. There is no colder plug available for the FiST.

    Elaborate please...I wasn't aware the NGK spark plugs I bought, as a direct replacement for the oem plugs, don't fit and cause problems...that's weird

    Well, I wonder why Amazon sells these as direct replacements...looks like I'll be returning these plugs

    Fwiw, Amazon is not an auto parts store.
