^^ you sir are correct..

I say stick with Denso. you can't go wrong and they're cheaper. I just wanted to try these out since everyone says NGK is awesome..

the techs at work say it won't make a damn difference lol

 

They're right. There's no such thing as a magic sparkplug.

 

One tech said to buy cheap spark plugs! Lol even thiugh our denso and ngk plugs last longer they dont conduct as good as the other materials (i forget). So buy the cheaper ones which conducts better and just replace em every 30k.

 

There aren't any. Denso and NGK are the only plugs designed for these engines. You don't have any other options unless you're willing to really roll the dice. And the whole "conducts better" argument doesn't hold up in the real world. Copper cores pull heat out best from a thermal conductivity perspective and NGK's marketing department has played on this for years.

 

This is my first thread so I apologize in advance for any rookie mistakes.
The OEM Denso spark plugs can be bought where? Im used to getting my parts @ Autozone which I heard is not the place to get new spark plugs.

In addition, where can I get the 3 gaskets for this intake manifold?

BTW I have a 09 IS250

I appreciate your help.

haha Nice icon.

Thanks Blitz!

 

I've never had any issues with NGK or Denso really, both are high quality parts. Toyota has used both in the past, though typically only offers Denso replacements.

I always use Densos, but I have used NGK's without issue before.

I've been told Denso makes the best replacement parts. Denso FTW !!! =)
