Is anyone still running NGK copper plugs?

[pandaudi]

Has anybody run NGK copper spark plugs at 3,000 to 4,000 miles? I know they tend to foul within those miles.

Since I currently have 2,786 miles on my spark plugs, should I keep them or change them?

[jackyaudi]

I think most people replace them every oil change, so along the lines of 5000 miles. Are you noticing any performance loss, misfires, etc??

[pandaudi]

Now that you mention it.... I notice after the car is warm up, theres this small bog like the car wants to shut off.

[rocketheavy]

i have almost 10,000 on mine and they still work great. not really sure what the hell you guys are talking about

I replace mine every oil change 5k miles and they always look good still.

i ran mine until 7K miles once and when i replaced them they looked to be toasted. i love running the NGK's though, at $8 for 4 you can't beat the price. easy to change them out at oil changes as well. my girlfriend's MKV GLI on the other hand is a different story. removing the engine cover to replace them every 5K miles is a b*tch! next time i'm going to get some longer lasting plugs for her...err more-so for me so i don't have to remove that damn cover so often!

[tamaneri]

i've been running these plugs for 30,000 miles! (not the copper ones)

whatever pieces of shit came with this car. Putting in new ones tomorrow woot.

I got the same problem and I have about the same milage on mine. Car's throttle response sux and before the car is full warm it drops below 800rpm and tries to turn off. It's stalled itself 5 times ion the past 3 weeks. Could be my boost and vac leaks though.

[Four Play]

I usually change mine every oil change, but it's been almost 8k miles on this last set and I haven't noticed any difference really.

I use BKR6E btw...

[rxrep]

NGK coppers here. Change 'em every oil change and re-gap halfway in between. Smooth as silk.

[vc1492a]

same here, I just change them every 5k miles with the oil change. ive got 4k on mine now and they still run great

[boy412]

I'm running BKR7E's in my car (one range colder) and love them! They get changed at @5000 miles along with oil, whether they look OK or not. Like somebody said for $8 its a no-brainer.

To the dude with the idle problem (after warmup) what are you gapping your plugs at? Checked your coils lately?

My car is a little grumpy UNTIL it warms up, but I think that's an environmental thing with these "colder" plugs. Will probably gap them tighter or put a set of BKR6E's in until Spring...per OldGuy's suggestion.

Gap size is .28...an my coils are brand new...must be an environmental thing then.

[B6480Avant]

Ive been running the bkr6e plug for 3500 miles and the car is starting to give me problems all of the sudden it wont start right up like it used to and im getting less mpg

do you guys think the winter blend makes a difference?

and these bkrse plugs ran way better than the autolite iridium plugs i tried first

REVO STG 1

[Denim'03]

I originally thought the same thing, that the NGK's were cashed. I decided to replace the o2 sensor because I would occasionally get a "response to slow" code. Problem solved, the new sensor fixed the crappy cold throttle response.

[dirtybrd]

Start running FR5DTC's

[LampyB]

wondering if my rough idle issue while using BKR7E's is due to the altitude that i'm at? no one else here has a rougher idle with 7E's versus 6E's at Stage 1+ right? i'm gapped at .028 and all four coil packs are new.

[B6480Avant]

are these the correct heat range for just a stage 1 revo flash? ive been thinking about trying these next

thats just nonsense!

[Mike02A4]

I just changed mine recently based off what i've read on here. They looked fine but I changed them anyway but went with autolite 3923s.

I bet it's happening since it got colder out correct? Run a warmer plug here in the CO winter. I run a very cold plug for this area (FR5DTC) and definitely would not run them if I had to cold start my car in 30deg or under. (My garage stays ~50deg)

Start running FR5DTC's

Agreed. Best plug I've found in my testing. http://www.audigeeks.com/forums/index.php?topic=3036.0

[NyteEscape]

im running bkr6e's, but now im interested in running FR5DTC's...

[CO AVANT]

They work well in high HP applications where heat and spark plug blowouts on the top end can be an issue.

[ApexIt]

does anyone know the difference between the bkr6eix and the bkr6eix-11? I really want to change mine out but am not sure which ones to get. I dont really need anything colder since im not tuned.

The difference between the two is in size they are pre-gapped from the factory. The -11 means they are pre-gapped at .044 or something similarly huge for our cars. You normally want to start with something pre-gaped nearer to the gap you are shooting for. There is a good link on the subject. I'll see if I can find it.

[Hamotee]

Two good links: One Two

[Drew-B6]

ok not to change the subject but I am running BKR6E with my APR 1+ with Bosch TT injectors. I don't think it is running very well and when it starts to boost i hear a spark knock (I think maybe, its some kind of cracking noise even worse when it is hot outside). Should I be using BKR7E?

You can try but don't be surprised if you have cold startup issues in UT winter, especially if you park your car outside... You should not be getting spark knock with that setup. You need to log to see what is really going on if you think your car is not running optimally. How many miles you have on those 6E's?

Jordan, in theory the Bosch FR5DTC would work on a 3.0 SC because right now I am running BKR7Es

[wolfdog]

Swap 'em every 5k.

+1
It's a different car with these in at startup (but once warmed up it's fine) and quite embarrassing with people in the car. I don't care, I'm going back to the 6E in a few miles when I do my oil change. My boost isn't that high that I need to worry about detonation yet anyway.

The FR5DTC's are just a better plug. At least for my application... Logs prove that.

ok, i will ask my tuner and try them out(my tune is very sensitive to changes)

[gotboost]

so it is ok to run the copper ones instead of the pfr6q plugs.... damn, i just spent $40 on theose

shouldn't they be gapped at 0.032 which is how they should come out of the box?, thats what i have them at and i haven't had problems at all

.032 for stock, .028 for chipped

[widgget]

yeah, tighten them up a little if you have any ECU upgrades.

[CO AVANT]

Gapping down didn't help the timing pull when I compared 2 different plugs in the same heat range... I run .032 FR5DTC's with the power levels I'm at. Never had an issue or found another plug with a smaller gap do any better.
