    Well, you're wrong there then..

    The question of vehicle ignition types is a side issue. However, I will point out, for others who question your motives, that the ubiquitous Nissan Micra (K11) has a distributor-based ignition system....

    Nissan Micra K11

    Literally millions of those cars were sold new, right up until 5 years ago. Many of the Micra K11s with their "jewel like" 16v chain-driven engines are still on the road.

    As such, that popular little Nissan model needs to have its ignition timing set with a strobe gun, to ensure efficient engine running. Incorrectly set ignition timing can cause an emission failure in the MOT test.

    A Micra K11 distributor (circa 2003).
    Note the slider, for adjusting the ignition timing with the use of a strobe gun.

    Typical ignition timing gun, or "strobe gun" (cost around £10-£15)
    I'd hate to see anyone buy cheap and buy twice
    Yawn.. This is laughable logic loaded with smear and hearsay.

    You've offered us no proof that the high cost "genuine" components last any longer than their "cheapie" counterparts. In fact, it is good practice to change lambda sensors on a routine basis, whether they have failed or not. Sensors tend not to function so well as they get older, so it's invariably a false economy to keep old, worn but exceedingly expensive, "genuine" sensors, to try and save money.

    Let's take the lambda sensor as the example..

    A "genuine" Ford sensor can cost £60 or more. Since this is "", please show us proof that those "genuine" sensors do last at least six times as long as the £10 equivalent, thereby saving us money.

    Furthermore, provide us with proof that the £60 sensor retained for six years, continues to operate to the same efficiency throughout its lifetime as the £10 sensor, replaced routinely once a year....
