just like the post says I need to know the difference.. I replaced my PKR7E's with BKR7'S and know have an odd misfire issue dont know if its the cause but it might be.. wanted to know what the differecne was..

 

i'd put my money on a bad wire. it just happened to me. what are your symptoms?

 

we dont have wires.. the stems didnt look all that great on the coil packs.. i get a misfire at WOT

 

Dont know about PKR7E, all i know is a lot ofthe BT guys here and on other sites like to use BKR7E. Do you get a CEL and fault code when it miss's? Make sure your gap is correct. If the gap is too big,high boost can actually blow out the spark and cause a miss. I was getting miss's at mid to full throtle before and diagnosed it as a coil pack issue, but it turned out to be a couple cracked plugs. Check that too. Ive never heard of anyone using PKR7E though.. Maybe try BKR7E and see what happens.

 

I have the BKR7E's in there now caped to .028, I noticed all the stems on the coil packs were a bit warn out and beat up.. can you just change out those for the 2000 a4.. i know you could with the AEB cars.. ill check all the plugs but they are a week old.. the car ran great for a few days.. I have no codes

 

Dont know about changing the stems for ATW packs. I looked at mine and there didnt seem to be a way to pull em off. If you do need coil packs, i still have my old ones that are fine.

 

Are you sure you had PKR7E cuz i tried searching the web and nothing came up. You sure they werent just old BKR7E's and the B was smudged and looked like a P?

 

^^^ That sounds like the case to me.

.28 is what most guys run however I haveheard BT guysrun closer to .25 and it seem tofix the WOT miss.

 

I will try changing the gap.. might be a coil pack problem i will see how much they are for new ones.. how old are the ones you have? are they for the ATW?

 

bkr7e is the best. I had some other NGK before ($11 each) and would not work better than bkr7e.

I use bkr6e right now because of cold weather.
