    i ran my 3.0 with ngk with no problems, are you sure it's not another part of the ignition system causing problems?, i have a brand new set of ngk for 3.0 if you want to try them, pm me your address and i'll send them they are surplus to requirement so just pay postage if you want to try them

    I've always used NGKs in everything that uses spark plugs.
    Like I'd put milk in a milk bottle, NGKs go in the car. No special reason why, though, I suppose.
    (Came across a set of Motorcraft plugs once and tried them, noticed no difference.)

    Lot of replica NGK plugs apparently about, especially the fancy Iridium ones!! Never had a problem with NGK myself, but 40 years ago l built a kit car out of a Bond Equipe convertible and it had everything brand new on it, and it ran like a pig, it was the plugs, but l think they were Champion.

    Can’t honestly understand how a spark plug fails short of falling to bits!
    Always used NGKs in mine, Pinto, Essex, and latterly the RV8..

    In what way are your plugs failing?

    My Laser with a megajolt setup is currently running on Champions... far better than the NGKs that I used to run. Had so many NGK plugs fail I was carrying around not 1 but 2 spare sets as they could not be trusted...the Champions I got at a local factor when they were shifting old stock at £1 a plug... I bought 3 boxes and so far have 26 plugs spare as they're lasting really well. I also run a 1mm gap which is probably what killed the NGKs.

    The ngks I had fail in both my Laser and my 2.8 both were fine when cold, then developed a misfire when warm and the Laser really didn't like it, spitting back etc. With the plugs removed, they measured fine electrically, so put them back in... same thing, fine cold but misfire when hot. The ceramics were fine so it must have been a cracked core on all of them (3 individual plugs).

    Been using NGK in my Laser for years without any problems. Perhaps they've changed in some way.

    I refuse to use NGK plugs.

    All my Capri engines has been V6, albeit the second one had a 2l Pinto which I hated.
    I need the the sound of a V6, Pinto seems lazy, don't like the sound of it.
    Have driven loads of Pinto engined cars, both stock and tuned, and did not like driving any of them.

    Back on NGK's.
    My engines were driven hard, and back in the day, only on 98 octane.
    When you were going flat out you could feel the NGK plugs was missing performance, same as switching from 98 to 95 octane.
    And those who says the octane do not alter performance, have not driven the engine hard enough or do not drive the same car on regular basis on the limit.
    Remember those days I drove 25-36000 miles a year.

    Beside performance, NGK's had lower idle speed, miss firing now and then, less MPG than Motorcraft spark plugs and pulled less compared to Motorcraft ones.
    And Motorcraft seemed to burn much better by the color, which should be a nutshell color.
    Also engines was pulling better with 8.5mm Magnecor spark wires and Lumenition electronic ignition on my Essex engine.

    And like Ford, some Volvo engines does not like NGK plugs, they seems to last way shorter than orginal Volvo spark plugs, mostly noticed by misfire in the whole rev range, both on throttle and coasting.
    People have bought new spark plugs only to find the engine runs crap, and when switched over to genuine ones, the problem goes away.
    These Volvo engines also seems not to like Bosch either, which is strange as Bosch is a quality brand.
    I recently changed my spark plugs on my Volvo engine from NGK to genuine Volvo ones and I could deffo feel the difference.
    And it reported all over forums that the V/S40 engines do not like NGK plugs, especially the turbo ones.
    The engine family of that era also includes 5 and 6 pot engines as in 850, V70 etc.

    So for spark plugs and sensors, I like to run orginal items if I can.
    Have heard the same on US cars of modern age, some will simply not run correct with some of the aftermarket brands, and will even throw up engine check light if such item is fitted if you are unlucky.
