How do my plugs look? - Honda Prelude Forum

CTPRELUDE · 09-09-2003, 06:11 PM

I checked my plugs after spraying several times and this is how all of them look:

Do you think I am running lean or do they look ok. I dont know if you can tell that well from the pic...

Edit: BTW they are zex plugs in case you were wondering.

I would say you are running rich.

Search on the nitrous forum and you will see a guide to reading your plugs. In my experience white speaks mean you are running rich. What shot are you running? The Zex plugs are 2 steps colder so you should be running rich depending on the shot size. I have been running stock platinums on my 70 shot with no signs of detenation.

running rich.

If you run rich they'll be "sooty" If you run lean they'll be burnt... kinda like stainless steel headers look.

Mildly rich, your good to go!!

Yeah, I'd say your plugs are looking just about what they should look like. The electrode is fine, there's no detonation evidence, and you're definitely not running lean, so it's all good.
