You will blow thru the E3's if your chipped/flashed. Iridiums gapped down to .028 are awesome too. The BKR7E's from NGK are a copper plug one range colder but only last 5k are decent ones as well. I like my iridiums gapped down with my N249 bypass mod, super smooth and excellent throttle response with minimal lag.
As were talking about sparkplugs, i think i need some new ones and which ones are good for audi a4 2.0l sport 2001? and something that will last longer than 5k
