I know the plugs tell you alot about how a motor is running:

Need some expertise advise on how these things look
Thank you.

60k plugs: To me they just a bit of carbon on them, I could probably run them longer but since im doing a valve adjustment I thought id change them


Stock plug: How pretty

 

See how the electrode, or whatever the hell it is, is rounded? That means your plugs are *very* worn. The color of them looks fine, just a little rich = good.

i wouldnt even run them for more than 5,000 on my car.

 

When I was turbo I was changing my plugs at every oil change, lol.

 

Wow!

 

I thought stock GS-R plugs were the NGK Platinums.. I noticed yours said Denso..

 

Maybe Denso Iridiums $$$$$$$

I run NGK copper plugs and change them about every 4th oil change.

 

Denso #PK20PR-L13

Can someone tell me if these are platinums?
Dealer sold me these, asked which Integra model it was etc
Hope they are the right ones

 

ngk and denso are the same company. like honda acura

 

On an Integra LS, how often are you supposed to change your Spark Plugs?

 

The electrode is fine (ie. not worn --> rounded). This is the shape of the electode on a platinum plug (eg. see the shape of the electrode of the new plug). Now if the plug was a copper plug, it would be considered worn.

BTW, you can go to http://www.ngksparkplugs.com/techinf...q/faqread2.asp for some very informative information (with picture ) which shows how to "read" a spark plug.

 

Acura uses NGK and Denso plugs as OE plugs. My '94 GS-R came with Denso platinum plugs.

 

Yes, they are platinum and they are equivalent to the NGK PFR6G-13. Look at the stick on the undeside of your hood. It should show you the NGK and Denso spark plug part number for your car.

 

as long as they aren't running white don't worry about it!!!

 

Good deal thx

 

Not true. They are two seperate companies.

 

The RS/LS/GS/SE use copper plugs and the service manual states that they should be replaced every 30,000 miles. They GS-R/Type-R use platinum plugs and they should be replaced every 60,000 miles.

 

BSQ: They look a little dirty how much longer will they hold up?

 

It's hard to say how much longer they will last. If they have 60K miles on them, I would replace them.
