33.3% gas mileage improvement on a 2003 Nissan Xterra with 240k on the odometer! OK, my math may be off, & it wasn't just this alone but along with MAF Cleaner, distributor cap, New air filter, fuel system treatment & synthetic oil change with filter. Previously the vehicle was using ¾ tank on a 90 mile round trip. Now it only uses ½ tank on the same trip.

I used the IK16 Iridium Power Spark Plug, to help get my car back on the road. After my check engine light came on, I went to the closest Advanced Auto Parts Shop for assistance. The staff was very professional & provided the information I needed to zero in on what caused the check engine light to come on. Once I got the code, I was able to determine what I should do to solve my problem. I purchased the IK16 Iridium Power Spark Plugs and now I'm back on the road.

Replaced Champion Plugs that were worn and rusted on the threads on a 1997 Dodge 3500 Van, GAS 5.9L, 248000 miles so far. I have had good results with NGK on my Toyotas... thought I would give them a try. Worked out well. I expect better gas mileage and power. I seem to be getting it!

E3 - DiamondFIRE Automotive Spark Plug: More Power, Saves Gas (Part No. E3.48)
DescriptionThe Spark Plugs are the product of years of fundamental research in the combustion field. The unique patented electrode configuration of these new The 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. E3.48 is a 14mm, 0.750 reach plug with a gasket seat. It fits a wide variety of late model applications, especially import. E3.48 is widely stocked in automotive retail stores. The automotive plugs have three legs securing the Diamond FIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented Diamond FIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use.
Product Features:- E3's Diamond Fire edge to edge ground electrode provides maximum performance with increased efficiency and a faster more complete burn.
- Smoother Acceleration & Idle - The faster flame initiated by the The 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 up to 6% on average in the typical operating ranges. Results will vary.
- Efficiency - The "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 larger flame kernel. The result is that more fuel is put to work during each combustion cycle.
- E3's patented Diamond Fire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
- The Spark Plugs are pre-gapped at the factory and cannot be adjusted.
