I just received an e-mail from NGK stating that its available. DFH6B-11A stock no. 6858; however I can't find it online anywhere.

 

I wonder if it's a colder plug or if they make one.

 

colder plug would be great!!!

 

yeaaaa find it and tell us =D
i am in need of spark plug very very soon.
im at like 59k >.<

 

I'm not too sure. I emailed them back but I'm still waiting for more info

 

This is what I got back from
them. "Check the link here: http://ngk.com/results_cross.asp?pid=6858&x=0&y=0* to find more information about this plug.* NGK.com is a distributor of our products in Southern California and should keep this plug in stock.* The heat range is same as stock for this Lexus.*

are these supposedly better than the stock ones or just cheaper, maybe both?

 

I heard from a few privately owned mechanic shops that our car's spark plugs don't need to be changed until like 80-90K. The 60K is just what the manufacture recomments. Can someone confirm?

 

You would rather listen to a shop then the manufacturer?

 

can anyone confirm on if the NGK are better then stock?

 

NGK is an OEM manufacturer FYI.

 

I thought the stock ones were Denso plugs? I think I remember reading that in another post. BTW the NGK plugs are more $$ than the ones we can get from sewell.

 

I wasn't talking about our cars haha

 

iSuxel, you got me confused there.
So NGK is better than the one from Sewell?

 

He's saying NGK makes plugs for other OEM cars. And with NGK being better than the Sewell ones, I remember reading another thread and I believe lobuxracer says he uses NGK all the time. Don't quote me on it though.
