Fit perfectly in my 2002 Subaru Outback 3.0 H6. Spark plugs are a necessary item to replace from time to time and with Advance's prices it is hard to overlook. Car ran smoother with a tune up and these plugs are a necessary part of any tune up if they aplicate to your vehicle. In my experience, use only the plugs that came stock in the vehicle. Do not "upgrade" to platinum or iridium if the vehicle does not specify those plugs. Also, do not switch brands. If NGK came stock replace with NGK.

DENSO - Iridium Long Life Spark Plug (Part No. F1000114522ND)
DescriptionThe DENSO Iridium Long Life spark plug was specifically designed for long service life and consistent performance in the latest, most advanced production cars DENSO's patented iridium alloy is more durable than even platinum, allowing the center electrode to be shrunk to only 0.7mm in diameter. This produces a dramatic improvement in ignitability and spark plug life. Closely related to platinum and exhibiting even tougher qualities, the rare metal iridium is an ideal material for spark plugs. A fine-wire, 0.7mm iridium center electrode is 360-degree laser welded in place using an exclusive DENSO process, and then matched to a platinum ground electrode. This pair of precision-formed, premium-metal electrodes dramatically extends the plug's useful life.
Product Features:- Fine-wire iridium center electrode
- Platinum ground electrode
- 360 degree laser-welded spark tip
- Sustained spark performance over 100,000 miles
- Withstands higher pressures and temperatures
- Reduced spark plug wear and erosion The DENSO Iridium Long Life plug has been selected as original equipment on many of the world's top cars, including those from GM, Toyota, Honda, and Mitsubishi. There's a simple reason for that: these manufacturers needed the best.

E3 - DiamondFIRE Powersport Spark Plug: Provides More Power, Faster Starts and Saves Gas, 1 pack (Part No. E3.68)
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. E3.68 is a 14mm, 1.000 reach plug with a gasket seat. It fits a wide variety of late model applications, especially Hemi applications. E3.68 is widely stocked 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 ground 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 up to 6% on average in the typical operating ranges. Results will vary.
- 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 larger flame kernel. The result is that more fuel is put to work during each combustion cycle.
- E3's patented DiamondFire Technology provides a cleaner burning combustion, which translates into fuel savings and reduced engine carbon deposits
- E3 Spark Plugs are pre-gapped at the factory and cannot be adjusted.

Decided to try out on my 2016 Chrysler 200, I noticed a slight difference in throttle response and fuel economy. Definitely going to buy again next tune up. Was using NGK Ruthenium HX plugs which are great as well no complaints but I prefer these E3 plugs over the rest.

Ap3923 plugs suggested life is 50k+. Previously purchased autolite plugs have gapped at recommended gap (.44) when replaced at 35 k in a camry whereas the same plugs (allegedly) had eroded Platinum tips on 3 of 4 plugs gapping greater than .50 on 3 of 4. Either the plugs purchased (2020) were defective (lower quality) or counterfeit which as suggested on YouTube have similar problems. What's interesting the recommended plug for a '98 camry is 3923 (mid temp) whereas denso and ngk recommend a mid high temp plug.
