    single platinum or laser iridium?

    Replacing all the coil packs. Been having some issues with at least 3 of them and found a full set on ebay for $180.00. So what the heck, I'll just do em all.

    But now what should I get for plugs? Do I spend $5.00 ea or $10.00? Not sure if spending the extra cash would be worth it.

    Your opinions please.

    Car has 95k on the clock btw.

    I'd spend a couple of bucks more for a spark plug of titanium coated with osmium. It is a pity that the marketers are not smart enough ..

    Is that an attempt at humor?

    If you look your coils are probably OEM as I have OEM coils in a CQ box
