I wanna get new plugs for my a4. it looks like the copper ngk BKR6E are best... but the question is, you guys keep saying gapped at .028 ... how do i gap them? and that doesnt make sense to me, if the plugs come 0.8 does it mean im changing them to 0.028 and isnt that too much of a difference?


sorry about the sillyness of this question, and yes ive done a search but noone actually explains how to gap them, or what these measurements actually mean

thanx

 

Gapping New Spark Plugs

 

thanx that helps heaps... doesnt answer one question though, u guys say gap to 0.028
when the plugs are originally 0.8

does that mean reduce it 0.8 - whatever = 0.028

isnt that a huge difference? or am i reading the numbers incorrectly

 

first off you are taking 2 different measurements so your confusing the issue either go metric 0.8 or imperial 0.028/28th, the plugs come gaped but it doesn't hurt to check them (they might have been dropped)

 

the correct plugs for your car if using NGK are BKUP6ET-10 and gap is 0.9

 

worth a book mark when converting

isnt it 0.711 for a chip? equal to around 0.028 gap?

 

by the way did u mean

BKUR6ET-10

if you did i think u should read this

says that plug iisnt good for my car being chipped and all...

 

NGK-BKUR6ET-10 are the ones recommended by Audi for stock that's for the 1997 AUDI A4 1.8T AEB engine the post you refer to is for the 2.8

 

NGK BKR6E gapped at .028-.030 is what you want for being chipped. They are copper, and will need changing every 10k miles or so.
