    yeah it is a 1.4. I just got some fresh 8mm Maginore leads but im still using the normal ngk r's, im sure just by changing the spark leads u wont see any difference. I been told by Maginore to get the best out of them I should use some "uprated spark plugs" like the platinum or iridium items, is this true or was the guy over the phone pulling my leglmao

    he was having a laugh unless you are running over a bar boost...if you can get a decent price from local autofactors go for the ngk gold palladium for around 16 quid the set as they are good. if not just stick with the ngkr's cos they do the job and at a tenner a set you can replace them every 6 months, which is far better.

    "ngk gold palladium"

    so the platinum or iridium plugs are only for turbo applications, what do the N/A high revving jap cars use?

    whatever the high priced jap dealerships sell them
    whats yours rev to (really) as i have a 7950/8000 on the astra and the bcp6ev cope fine
    you dont need to spend more than 15 or so quid, just make sure they are regularly changed/cleaned

    ah rite, cool. Although, 50k miles they last. SO I dont think im gonna need to change them while I've still got the car

    Might be a good idea to hop over to www.noswizards.com onto the forums though. People ALWAYS wanting the better sparkplugs.

    AFAIK platinums are specced for longer life rather than any increase in performance of the plug, that said by the very nature of their longevity after 10k miles theyll be performing better than the equivalent standard plug.

    DaveB, id be surprised if you got that sorta life from em in your application, they might last like that in a standard zetec or similar but in a higher CR engine like you have and with gas too its unlikely, that said still better than the standard item.

    B8 GHY, if you wanna make sure that your plugs are up to it as said regular cleaning is one of the keys to it. Regular changes if standard plug type, not so with platinums. Maybe try DENSO plugs, some applications have the U groove type ground electrode, sposed to improve spark diameter or summat, swear by em in me valver although twin prong golf plugs go well in there too.

    which is what, nova gsi power? why on earth do you imagine the peak power to be up near 7.5k and why on earth do you think it could give a cav gsi a run for its money or it needs 50 quid spark plugs
    is it a goodun then?

    yeah dave, its not 50k its 10k like standard service item, less with nos maybe
