    What are the Best Spark Plugs for the 8th Gen

    What are the best spark plugs for the 8th, with the perfect heat range(500 - 900F)?

    I was using, NGK regular, but it was running too cold, so carbon deposits wasn't burnt. It was covered in black soot.

    Any ideas if NGK iriduim will do the trick?
    I used this one, but the same thing happened. I don't think burning oil has anything to do with spark plugs, because even if the engine did burn oil, the plug is supposed to burn off the carbon deposits on it.

    I usually use Denso or NGK Iridium plugs.

    You can run NGK Coppers if you want a plug that will run hotter. Downside is they have to be replaced every 10-12K.

    you referring to the pulstars? if so, i have those and cant tell that much of a difference if any. Tried messing with the gaps too to see if it would make a difference, but nope. rollatuner uses them too as well, although im not sure how well its working for him.

    I use NGK Iridium myself. I'm sure either NGK or Denso works just as well.

    I have the pulse plugs on my non-vvti 1ZZFE and I can tell a decent difference in throttle response and slight powerband gain. Nothing huge, just peppier. vvti may hinder any gains by the plugs. I've ridden in jcrwzr's Corolla with the pulse plugs before the crash and I felt no difference either, so must be due to vvti.

    listen to this guy.


    pulsestars are a waste...they are meant for hybrids and diesels...i talked to their customer service rep when i was replacing my plugs.


    denso OEM's from the dealership are 2 bucks a plug...or something..
