I ran torque master plugs for a good 60k miles and then started to get heavy misfires one day etc. I changed back to new Denso Iridiums plugs and gain some MPGs and my misfires went away. Reflecting on my current repairs I think the TorqueMaster plugs worked fine it was my OCV that went out which caused my plugs to miss fire. Anyhow OEM is the way to go OP.

If I recall Denso or NGK Iridiums are OEM. I didnt set the gap on my new plugs either hmm wonder if I need to.

Well it looks like I will do the OEM thing.

I figure I will change out the plugs when I am in there changing the starter (WHO PUTS A STARTER INSIDE THE ENGINE!!!!) as well as my p/s pump.

But I will wait until the snow blows out of Oklahoma...my baby just looks so cold sitting in the garage!!!

Thanks everyone for their input....

Torque Master on my GS300. It feels the same IMO. Im going with OEM next time i change it.

The eyelids looks like the hood is too small, at first glance i thought ur hood was open.

read a lot about TM plugs......inconclusive and for the heafty price it didnt make sense and not worth the risk, no racing guys use them that I talk to....if they were really that great everyone would know about them and be using them.

Iridium IX here cant go wrong
