These are the o lyrics plugs you should be running in your LS based engines if you don't want to be changing the plugs every 30k miles. Smooth idle is another reason. Yes I like ngk also but only for power adders.

E3 - Premium DiamondFIRE Electrode Automotive Spark Plug (Part No. E3.54)
DescriptionE3 Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new E3 spark plugs increases the amount of combustion pressure created during each power stroke of an engine, which results in a marked increase in power output, fuel economy, and reduced emissions in all gasoline engines. E3.54 is a 14mm, 0.708 reach plug with a taper seat. It fits domestic applications, and is widely available in automotive retail stores. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.
Product Features:- E3's DiamondFire edge to edge electrode provides maximum performance with increased efficiency and a faster more complete burn
- Smoother Acceleration & Idle - The faster flame initiated by the E3 spark plug results in a more complete burn of the ingested fuel charge. More pressure is created against the piston more fuel is put to work
- Energy - Power output improved by 6% on average in the typical operating ranges
- Efficiency - E3 "diamond shaped" side wire electrode projects the combustion spark in a way that more quickly ignites the air/fuel mixture, thereby creating a significantly faster and longer flame kernel
- Emissions - E3 provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
- E3 Spark Plugs are pre-gapped at the factory to meet O.E. requirements
- Warranty does not cover plugs installed in any modified engine or used in any racing, aircraft, or commercial application. Spark plugs damaged by abuse, accidents, or improper installation or applications are not covered by this warranty.
