Alright back in the day I had a Civic with a D16Y8 in it and I had a dry shot of nitrous on it. Darrell *** if anyone knows who he is told me to run Champion C59 Race Plugs in it because of the nitrous and these plugs were colder and worked really well with nitrous.

I still have them and just installed them into my SR20DET which was wanting to lean out last night with the new plugs that I installed in it some NGK BKR6ES-11. I know that the heat range on these plugs is a little on the hot side for turbo but I have ran them before without any real problems. Last night on the other hand my car wanted to sputter when I would boost it up so I decide to check my plugs. Low and behold the tips are white!!!!!!! I took them out and threw in some old Denso plugs that I had just took out and it ran alot better.

I just wanted to know if anyone ever experimented with these plugs and if they liked them or not. Any pros or cons

 

nope never tried them before. always used ngk bkr7 or bkr8 in my FI rides,boosting at least a bar.

 

Cool I just went on a little test romp with my car. It ran about like it always has with the Champion C59's in it. Ill give them a few days and see how it turns out.

It seems like my plugs are a lighter shade then they have been in the past. Is it possible that I have got some bad gas in the tank? Making it run leaner

 

I use them

NASCAR plugs

 

So they should be pretty good for my forced induction setup right??

 

I've always had good luck with champion plugs..
