NGK - 4996 IFR5T11 Laser Iridium Spark Plug, Pack of 1

Product Review

NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This tapered cut iridium center electrode reduces the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. A platinum tipped ground electrode further contributes toward the extreme longevity of this plug.

If you have 1ZZ motor in your Pontiac Vibe, Toyota Matrix, or Corolla, this is the right spark plug for you. It is what our cars come with OEM, price is right and with free shipping, you cant beat it.

I had a BAD experience with Bosch plugs.... beyond bad. After that I tired NGK plugs and I have been using them ever since. They have never let me down and still burn clean after a lot of miles.

For work we use a lot of old Crown Victoria former police cars and we swap out the plugs right away and use NGK plugs. They always run much better and cleaner with NGK. I will keep using NGK plugs until I have a good reason not to. Prices always good too.

Replaced stock Denso plugs with these NGK plugs in my 2007 Toyota Yaris HB. Car had 65000 miles on old plugs. Definate performance increase. Engine runs smooth again and a noticeable increase in power.
