NGK bkr6e vs bkr6e-11

[salz2135]

I remember this has bee talked about but the posts must have been lost.

I want to confirm that the only difference between the NGK bkr6e and bkr6e-11 plug is gap from the manufacturer? Or, am I way off.

Thanks guys.

Yes the gap is different but.....

If you start out with a plug that is made for a 0.044 gap, you'll have to bend it inward quite a bit to get to 0.028". This will leave the ground electrode at a diagonal angle to the center electrode.

Just get a set of BKR6E and start with them. Stock number is 6962.

When I picked up the -11's (all the store had), I gapped them by pushing the side of the strap in, and pushing the end up to keep it perpendicular:



(yeah yeah - crappy pic but you get the point)

It worked fine - no signs of the strap burning out after 30K miles (or somewhere there about).

^^^^^^^^ you should be replacing copper plugs every 3-5k miles. not 30k. just fyi

well then it just goes to show that gapping that way worked fine!!

That's 30K(ilometers) -my bad but w/e. 3-5K sounds overkill to me. Once/year is ok in my books.... and so is cleaning my air filter once/year!!

I had a terrible time with the 11s with my stage 3 A4, best to stick with the 7es if ya can.

Yeah, I'm running BKR7E gapped .028 on the audi

I have a set of bkr6e in the garage and my sister's suby runs the 6e'11's I wanted to check to see if I could run the plugs in her car since she's due for a change.

the -11's should have no problems as long as you gap them corrently.
Unfortunately, I just couldnt gap it evenly so I got the non-11's.

i know this has been covered but since this thread is here, the BKR6E are ideal plugs for the cold on just a chipped/exhaust setup correct? and the 7E's are better for warmer climates with the same mods? my plugs i have in there have been misfiring on very cold start ups when idleing.. i couldnt tell you what they are, ill check tomorrow

6e is oem heat range, 7e is for higher powered heat range. everyone who has posted thusfar can probably run the 6's

So here is my question: How big of a difference does new plugs make? Because recently my fuel mileage has dropped about 4mpg.

[onemoremile]

Fresh plugs do make a difference. After 3k miles I can start to feel a touch of hesitation and my mileage drops off slightly. After 5k miles it is quite noticeable. I've gotten into the habit of changing the plugs every time I change the oil which is every 3333 miles.

FWIW, that -11 indicates a 1.1mm gap.
