Has anybody used these spark plugs in the're car? B10EGV's

Let me know if you like them.

 

It's a good plug but plan on having a rough idle.

 

I ran B9EGVs with a smooth idle for years. Now am running BR9IEX.

Not much difference between 9 and 10 at idle if you have the AFR leaned out
to prevent fouling. You can easily run about 16AFR at cruise with no problems.

 

I've had problems and people locally have had the same problems running the 10's with a 12 afr at idle.

 

i run B9egv with the stock ECU, no problem. also run them on my FC which has 420hp and CDI, though will upgrade to b10egv. only problem is you need to shave down your spark plug socket to fit them, they are made to suit 2-stroke dirt bikes

 

What gap? I ran a b10egv with a gap anywhere from .022-.024 and never had any problems at all. They also lasted longer than the regular plugs most people use, even with me daily driving it. My a/f at idle was real rich too(in the 11's)

 

I didn' gap them at all. I thought the best gap was what came out of the box. I thought I read that somewhere here?

I'm wrong I take it?

 

I run BR10EG's on all four. My idle is better than any other 3rdgen I've been in so I dont think it directly affects idle. The socket part is a pain and I do change them frequently. Running about 350-375 rwhp.

Oh and they come gapped .022.

And does anyone know the difference between EG and EGV? I dont know how I ended up running these EG's but I have been using them for about 10K miles.

 

I have used B10EGV plugs. They were less prone to misfire at high RPM than the BUR9EQP plugs I was using, and I never had any trouble with idle. I think my idle AFRs were 13:1-ish, but I have them around 15:1 for light cruising. I did not have any trouble with fouling the plugs. I have found that they are gapped appropriately right out of the box (0.022-ish). You do need a shaved socket to install them.

Anyone know the OD for the shaved socket? I want to turn one down on the lathe.

 

Anyone?

 

Barely larger than the points on the spark plug hex. The walls are VERY thin at the corners/points. And the RB socket fits the hex much tighter than your average spark plug socket, so it might even be that you need to turn it down so much that the corners are gone on a normal socket.

www.kgparts.com has them under the DIY section. Around 20 bones shipped, and Keith is a good guy so I buy parts from him whenever I can.

I have a set of the b10egv's sitting at my house, going to toss 'em in this weekend in anticipation of a forthcoming high boost tuning session. If SPO ran em when he trapped 125 on pump gas, they're good enough for me

 

Do most of you guys run them for leading and trailing?

 

pretty sure. That is what I am planning on doing.

 

Nice ... does that mean that we are going to get to see a "high boost" dyno run with your BNR's in the near future?

 

Yes, I run them in all four spots. But I might try some EIX (iridium) ones once I wear out my supply of B10EGV plugs.

Eh, it's kind of fun to just tease you SOBs

On a serious note, as soon as ol' JD can tune my rex, I will hopefully have some nice results.

I ran the b10egv's a few times. They were gone after about 300 miles or so due to rich idle . But who care there like 3.75 a pop here at advanced auto

 

Thanks!! If I can save $20 by turning down the socket in a couple mintues, then why not try. If I screw it up I'll try again on another $5 socket. :o)

 

At Sears:

"Um, yes, I need to replace this socket. I was like loosening this bolt really, really fast and there was like something rubbing the socket or something. Anyway, I need a new one."

I bought a cheapo thin-wall socket from a motorcycle shop , it's made of weak metal that's easy to grind down. You really do need to take a lot of material off. It took me a few tries to get enough off so that it would go in the hole. The BR9EIX plugs are nice though, after 3.5k miles the electrodes look to be in good shape, compared to BUR9EQ's with 3k on them. I think I'll try for 5k with the next set of EIX's.

This week, I asked for EGV plugs, and the guy at the motorcycle shop said that NGK has quit making the 'gold' plugs.

You dont have to go to a motorcyle shop to buy them. Anywhere that's a distributer for NGK should have them. Advanced Auto, Auto Zone ect ect.. If you get them from a motorcycle shop you will probably pay alot more for them.

 

I run 8/10's NGK Iridiums with a streetport but was told I should do 10/10's. I'm not shure why the leading needs to be just as cold if it only fires 1/2 as much. You can get the plugs from sparkplugs.com, just do a search for the part #. I got the socket from KGParts. The great thing is they are cheaper then regular oem copper plugs and yet better.
