Spark rattle ...

Post by coolen »

I recently put a set of iridiums in my car, v6, 1992. Now I'm pretty sure I'm hearing spark rattle. I tried bumping up a octane level and no change. Should I try supreme gas?

Thanks

Actually the v6 engines are designed to run on premium for optimum detonation. Otherwise I hope your not talking about bosch iridiums, I tried those once and it ran like garbage, ever since Ive stuck with NGK platinums.

If it's stock K8 then just stick with what factory recommends. No need to waste money on "special" spark plugs, you won't gain any power, actually might hurt it. Also make sure you've gapped them to the spec.
