??? on Plugs

[TWAN]

Just need your opinion on going to a colder plug on a sr20det. I was currently using a BKR6E-11. And just last night I switched to the BKR7E-11. Well I actually had to go with a Champion plug that was the exact to the NGK minus the V-Power. I was running the BKR7E-11 in my last car on like 18lbs daily driven and had no problems. But I was just curious of your opinion of using this plug in a Nissan running .5 bar.

When I pulled the plugs last night they all were in really good condition. They were a light gray with some brownish color in them. And from what I have read on plugs they looked in perfect condition. If I had a pic here at work I would post it. But my reason for the question was just that they seemed a little to close to being on the lean side. That was my main reason for going to a colder plug. Also after the change I noticed that the idle wasnt so jumpy like it was before. Had a real smooth idle. And when I boost I didnt have the lag like before throughout my rpm range. Before the car had a real bad lag going into boost. Just didtn feel normal.

Any comments or help if you know or can correct me on anything would be great. Plugs and fuel are not really my great side when working on cars. I normally leave that up to the computers.

Thanks

I guess you could make sure they are gapped to .28

i would spend the extra dough, and order a set of BKREIX's from http://www.enjukuracing.com (same as http://www.sr20detperformance.com)
