Which bkr7e?

[02s4audi]

I'm not asking what core plugs to run (copper, iridium, platinum). I have read that copper is best. My car is a stock s4. Which brand copper plug is best? Also I know ngk is good but I see they have a standard copper and a v power? Which would be better? They are the same price. Also should I run bkr7e's or run bkr6e's until I go stage 1 or anything else?

[Timtheguru]

NGK 4644 (BKR7E part number) best V-Power copper plug you can get.

Less than $1 each.. change every 4-5k miles for best performance. Can drive on them for longer.

[02s4audi]

What gap should I use? .26-.28 for stock right?

[02s4audi]

Is v power better than a standard plug? Ngk makes a "standard" copper and a "vpower" copper. I don't get the difference.

[02s4audi]

Anyone? Should I run bkr6e's or 7's for my stock application? I know 7's are good for chipped and I will run them chipped. Also, what gap?

[Luis_Heineken]

stock? i put some ngk iridiums in my b7, so far so good

[02s4audi]

I've heard the coppers are better and I don't mind replacing them every 10k or so. Can anybody else chime in?

Iridiums and Platinum are used for longevity, copper is a better conductor which results in a stronger spark.

Bkr6e is the stock heat range. Bkr7e should being fine, gap should be between .025"-.028". They come pre-gapped at .032".

[jpurre]

NGK BKR6E @ ~0.032" for stock.

[hibiscusS4]

wait really my bkr7es came .025 i thought unless i just really suck at using my gauge.... maybe thats why i have slight misfires

I've had great results at 0.025" with the BKR7E's @22psi. I always have to tighten them down to 0.025" because they come in all kinds of random widths from the mass production factory.

[hibiscusS4]

ill have to go home and re gap my plugss first time using the copper plugs but so far there good i get a slight misfire at idle but up to 20 psi on the f21s and its fine

[AudiSportB5S4]

I run the 4644s @ 0.025 also. Peak boost 23psi. Run smooth, no complaints.

[02s4audi]

So would 7's or 6's be good for my stock car. Idk if my location would affect anything.

[jpurre]

Stick with heat range 6 for stock.

[V1nny]

Use heat range 6 for stock boost. If you use 7 on stock boost, especially copper, expect them to foul soon. Even stage 1 is ok with 6. Stage 3 (k04) better off with heat range seven to avoid detonation. Also the whole concept of copper plugs having stronger spark while technically true, is more of a bull in practice. Iridium is pretty much the same as copper. Platinum maybe slightly weaker spark, still perfectly useful. If you obsessed with better spark for some reason, replace coils with 2.0t newer coils.

[02s4audi]

I just don't have the $100 to drop on iridium plugs right now. And I've heard copper is better and for a 2.50 a piece and changing every 10k I'm fine with that.

[02s4audi]

You figure it's ROUGHLY $100 for iridium a for our s4's. You spend on average $15 (2.50x6) for coppers, switch them every 10k. You'll get roughly 70k before the price becomes the same. As long as you are willing to change them more frequently then it's not a problem.

http://www.ebay.com/itm/111620998779 also $39 to $42 in my local parts store for the same set of 6.

[02s4audi]

Then what are the benefits of each because everyone I've heard from says run copper. Which should I realisticly run?

[02s4audi]

How long will the iridiums last? Are they better than the platinum plugs the car comes with?

[02s4audi]

I'm not worried about the best spark possible. But I want the car to run properly and not die. I've heard stories of iridiums and platinums giving way on people and I don't want that.

[HighPsi(NorCal)]

No, basically the same thing, run what Audi recommends.

The difference between copper and iridium/platinum is minimal if you are putting around on stock boost levels, once you start upping your boost you will need to begin to think about the other variables (gap, spark strength, ignition components, etc..). As has been said, if you don't mind wrenching on your car, replacing plugs every 10k, imo, is well worth the savings that is foregone by not using the longer lasting iridium/platinum plug (on stock or modified boost levels). I run copper additionally because there is a better chance that I will burn my plug down first instead of the motor where the same cannot be said about i/p.

I've been running OEM spark plugs on my S4 for 70k miles. Installed them when I was Stg2 around 80k miles, and still running them now at 150k. Been Stg3 for the last 35k. Use with stock coils and FSI coil conversion. I think they were somewhere around $100 from the dealer, so probably cheaper elsewhere. Never had a spark plug related misfire issue.

I don't especially like the idea of cheap spark plugs and I don't feel like changing them frequently. I know it's probably rare or maybe I'm making it up, but I've heard of cheaper plugs disintegrating and dropping chunks into the cylinder - aint nobody got time fo dat!

[threeputtpar]

All spark plugs have a copper core, it's just the material on the tip and ground strap that varies. Platinum and Iridium last longer than just the normal nickel plated steel ground straps.

I've been running BKR7Es in my stage 1 for 30k miles now and have noticed no gap erosion. At $1.99 each (Advance Auto with a 30% online discount) it was an easy decision. I've played around with gaps ranging from 0.025 - 0.032 and have noticed no difference. No need to change them every 10k miles, unless your other ignition parts are not up to snuff.

I was about to say that..

[flips4]

Yes, copper is a better conductor of electricity than iridium or platinum. but it wears out quicker. you might get 100k mile out of platinum where you would get 10k out of copper. My dollar is on copper. Ran bkr7e for the last 12 years.

[MacDaddy]

all spark plugs have a copper core, only the tip is iridium, or platinum or whatever they put on the end.

I am rocking a heat range 7 NGK Iridium in my stock S4, misfires less, seems to run fine.

I one time tried NGK V powers and it ran kinda crappy, like increased fuel consumption and laggy throttle.

[01audia4]

I foul out BKR7E about every 3k miles without a doubt. Not running rich 2.0 coil conversion F21 car. I have no idea why but it's getting old, especially because I've been putting 3k on my car every 2 months.

[02s4audi]

So between iridium bkr6's and the factory pfrq6 double plats, which one should I choose from? I've decided to run either of those for longevity because I'm not chipped or anything right now. Once I get chipped I will stick to coppers. But for now which one of the two? Stock ngk laser double plat or bkr6 iridiums? Also should I gap either of them? I've heard they come pregapped and you can't really gap them because they are prone to breaking at that point?

[killerkali]

My car misfires on anything but BKR7Es, gapped to .024" is perfect with 2.0t coils.

[MacDaddy]

if your stock i would go with a NGK 6 heat range g-power, dollar per dollar the G power is your best value IMO, its what i go for when available, otherwise i go iridium.

[CELison]

Buy bkr6es, gap them, put them in your car, and call it a day. In 20k miles, spend another 14 dollars and buy another set.

[02s4audi]

Whats the difference between g power and v power?

[02s4audi]

Can you reall get 20k out of a set of coppers?

[V1nny]

My car misfires on anything but BKR7Es, gapped to .024" is perfect with 2.0t coils.

do you have some huge turbos installed with insane boost? .024" sounds like pretty small gap for 2.0t coils. I have latest revision black 2.0t coils, k04 stage 3 and gapped iridium BKR7E-11 .03 last week. So far no misfires. Got about 14K miles out of coppers before multiple misfires started.

[NOTORIOUS VR]

Can you reall get 20k out of a set of coppers?

Yup.

[02s4audi]

This is still complicated. So many different opinions. I want longevity and no misfiring. Whichever gets me there. If I have to change them frequently (copper) to ensure no misfires then I will. But no misfires and longevity would be great.

[02s4audi]

What's up with these?

[01audia4]

Yup.

My car says opposite. I've been told constantly to get 7e's though, why 6e?
