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.

          Works in both my 09 Subaru and a Husqvarna Riding Mower, had a laugh when I was able to cross reference a cheap Champion QC12YC spark plug to these NGK Iridium beasts! Already remembered the 5464 numbers when I replaced the stock Subaru plugs at 75k as a 'preventative maintenance' item. I no more worry about fouling out cheap Champion plugs due to heat or fuel issues in the air cooled 'Brigs and Stratton engine'. Both Car and Mower use less fuel also a plus. NGK, Subaru, DSM 4 Life :)

                Great plug. Upgraded from platinum to these in 2000 GS300 Lexus. Smoother idle and response when u hit the gas. I also put in NGK plug wires as well. Well worth the investment. Car runs like a champion. Noticeable difference when u upgrade from platinum plugs and get new plug wires also. I will upgrade with these plugs n wires(NGK wire set), for my Frontier pickup when its due for a tune up!

                    A:

                    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.
