Installed some BKR7E-11 Spark plugs... Power loss?

[brandonp]

I installed these plugs a little while ago, gapped them properly and whatnot, and now my butt dyno is telling me I am not pulling as hard.
What could be causing this? Would it be obvious to me if I was constantly misfiring? I though it would me.

Maybe I am imagining it all.

Help.

the s11 at the end means its the longer threaded version... you need the bkr7e NOT s11

[brandonp]

f*** me eh

[317ssayzarc]

hey its not so bad... just get the right plugs for less than 10 bucks at NAPA and spend the 15 mins puttin em in... no biggie, as long as they didnt thread past the deck

[belinko]

how often do you guys change your plugs?

I know its been discussed, just curious.

I use bkre6 and I change them every 10K?

[317ssayzarc]

i change my bkr7e's in my golf every 5k-10k, depending on how the gap and center electrode are...

[belinko]

basically about the same here.

[biketsai]

I thought the BKR7e's should be changed like every 3k?
I was about to buy new ones, should I? I have ran them for 3k, should I recheck the gap (what should it be at .32?)

i set my gap to .028, as long as its not misfiring your good

I change mine every 1/4 mile.

[andyrew]

I've had mine in for about 30k miles.. I inspect them every oil change though...

NKG's... the 4 point tip ones..

lol, I was just kidding. My last run at the track a few weeks ago was on the same plugs that were still in the car from when I ran back in Sept last year, someone even told me they looked fouled when trying to figure out why my oil was foaming up. I run the bosch F6DTC plugs which are $4 each.

[Seerlah]

I read that the Bosch F6DTC can run up to 25k before needing to change. Hey Mike, is there is a certain franchise that carry those plugs. I had to order mine and Autozone and Autoparts does not carry them.

No. You can get them from 034, Eurocode or if your on the east coast RockAuto. I was looking into buying a case of them at one point, still need to since I always need spares.

Aren't the -11's the ones with the .044 gap?

[brandonp]

Well I regapped... They were at around .035ish before gapping.
So this could be why I am experiencing less power? The gas isn't combusting properly because the plug is seated too deep into the cylinder because the threads are too long?

[317ssayzarc]

just get the right plugs! they are less than 10 buck a set lol... gap em at .028 (the NEW plugs) and see what you got

[Squarrl]

what do people think of F5DPOR?

I run bkr6e on my gtrs, gapped at .028. I think that its recommended that you change copper plugs every ~5k, so i just do it with oil changes (failing plugs really are really noticable my gtrs). Also, I hear that they will never seal up as tight if you remove them to inspect them, and put them back in. I'm not entirely sure if that is true, anybody else ever hear the same thing? Also, I torque them to 22.5 psi.

eh, i pull the ones outta my audi regularly and re-install them... no problems here, and i dont use a torque wrench

i used to change my bkr7e w/ every oil change, but i have been running these same ones for almost ~10k and no misfire problem.

same here, im at 10k on this set and my golfs fine... powers a lil choppy before it warms up (even at part throttle) but other than that theres no ill effects

Brandonp, Why are you using 7RE's? What are you mods? I've personally had bad luck with 7RE's. I've had better luck 6RE's.
