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.

Comments about NGK Iridium Ix Spark Plug (BKR5EIX-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!

          These NGK Iridium plugs were OEM in my other car and I found out they had an application for my 2004 Tacoma 2.4L so I decided to try them out instead of changing out the OEM standard plug every 30,000 miles. I think they added a little pop to the acceleration. Hoping they improve fuel economy too, but I don't drive that truck as much anymore.

              These are some great little plugs. I noticed immediate increase in performance. The engine in my Subaru Baja seems to be very happy to have these plugs firing away. I cannot attest to their longevity quite yet, but I think if they last at least 50K, I will purchase again. They seem to be well worth the price.

              NGK makes the only iridium plug on the market with a solid iridium center electrode. Advance Auto's price is as low as it gets on these fine plugs.

                I was told by my mechanic friend to purchase this spark plug to improve the performance of my 1999 Mazda. The website was great as I plugged in make and model and they recommended the correct plug. I hope to keep my car for another year and I just might make it with the help of Advanced Auto Parts.

The Chevrolet vehicles this particular spark plug fits are 1998-2002 Chevrolet Prizm and 2001-2004 Chevrolet Tracker.
