Installed this myself on my 2001 Nissan Sentra SE 2.0. The set does not come with anti-seize grease so better buy your own, it is worth the money. Installed it very easy, on a perfectly cold engine, tightened it by hand and then additional quarter turn. Immediately I noticed better cold start,engine purring, more power in high revs. Motor became more responsive and less sluggish.
Used Denso on another vehicle, but this time I went for NGK because this type has iridium core, and Denso has copper. NGK is better priced too.

This plug is listed as an exact fit for the 1996-2002 Toyota 4Runner. This is NOT true. The 3rd generation 4Runner takes a dual electrode plug. The correct plug is part number 3967, NGK number BKR5EKB-11.

    Had to change valve cover gasket figure it was time to change plugs as well. Original had 72,000 miles on them. Had to rest gap for my car not the manufacturer fault Nissan seemed to change gap size for this engine several times. Once rest put in car engine runs much smoother. Just be sure to put anti seize on plugs. Original had not and weren't fun to get out.

        I purchased 6 for my vehicle and it made such an improvement in the idiling and the acceleration of the vehicle. This is a highly recommended product. The only problem I had is that they all needed to be gapped to suggested manufacturer recommendation. I used a wire gap tool, made the necessary adjustments, and wolla!

                  Hi MR G, I'm happy to help you! This NGK Iridium Ix Spark Plug (BKR5EIX-11) - Part No. 5464 is an exact fit for your 2004 Ford Thunderbird. This spark plug feature an ultra-fine center electrode that's designed just thick enough to ensure the maximum durability and life of the spark plug, and just thin enough to create an accurate and consistent spark. They represent the ultimate evolution of spark plug technology and performance. Iridium is significantly stronger than any metal used in spark plugs today. It's the hardest metal used (in fact, iridium is 6 times harder than platinum), which has allowed NGK engineers to reduce the voltage requirement for a spark.
