Someone told me it will really show the diff by denso sparkplug for a mods TL.but which should i get ,IK16 or IK20??My 00TL with i/h/e/p/Stb.please discuss about before i buy them,then I'll let you guys know does it really do the job.thanks

 

well i read about it a while ago and it seemed like the IK20 was better for modified TLs so i guess that's what you should go for.. let me know how it goes i might get some too...

 

IK20 with the mods you have.

 

From what I've read, modified meaning turbo charged, supercharged and nitrious use IK20. Other than that use IK16. I just bought NGK iridium IX! I also spoke to a sales rep for spark plugs and he told me the same.

 

No, if you have headers you can go to the colder plug.

I've been running the IK20 for a few years now and I've had no problems.

 

you can use a colder plug, but it isnt necessary with just headers...FI is really the only reason to need to use a colder plug.

 

Ok i made my decision,I'll try to go for IK20,and I'll let you guys know the result.Thanks guys.

 

what kind of difference do plugs make!?

 

nothing really, just a maintenance thing. you do need "colder" ones if you increase your HP alot - with turbo or supercharger or something extreme like that
