    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):

      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!

        Comments about NGK Iridium Ix Spark Plug (BKR5EIX-11):

        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.

          Replaced original plugs on 2005 Corolla at 120,000 miles. They immediately smoothed out the rough idle. Noticed an improvement in acceleration response. Very pleased so far

            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.

                  Iridium spark plugs are the best, they last a very long time 80-100k miles. NGK are also one of the best plug makers. These fit great into my 1995 Subaru Legacy and will likley last longer than the car.

                        I am looking at the installation instructions on the NGK website, specifically the torque specs. The only thing not listed from either of you is the seat type. There is a flat seat type and a conical seat type, both have completely different torque specs. Which seat type are these iridiums ? I have a Camaro and have only used AC Delco parts, but their iridium plug doesn't fit my car...so I'm going NGK ! Thanks !

                          I'm happy to help, Don! I did some checking on this part and it doesn't indicate that it's an exact fit for any Chevrolet Camaro. The Chevrolet vehicles this particular spark plug fits are 1998-2002 Chevrolet Prizm and 2001-2004 Chevrolet Tracker. If you could please provide the year and engine size of your Camaro, I can assist in locating the correct iridium spark plugs for your vehicle.

                          No, I am sorry. The NGK Iridium Ix Spark Plug (BKR5EIX-11) (Part No. 5464) will not fit your 1995 Nissan 300 ZX. Please check the NGK Laser Platinum Spark Plug (Part No. 2867) instead. This would be the right part for your vehicle. For further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.

                        Would I have to upgrade my wiring to performance wires or would the stock wiring be able to endure the extra heat?
