    L76 spark plugs

    If you want the longest lasting(no fun to change), best performing spark plugs for a '67 L36 and don't mind paying a little more for them, what do you recommend?

    Re: L76 spark plugs

    The latest generation of iridium/platinum/unobtanium plugs being fitted to today's cars are good for 100,000+ miles. If you can find the crossover number from the stock OEM plugs in a suitable heat range you'll be all set.

    Beware weird aftermarket multi-electrode zoomy-blaster plugs. They do nothing for performance.
