6 New NGK Iridium IX Spark Plugs LFR5AIX-11 # 4469

6 New NGK Iridium IX Spark Plugs LFR5AIX-11 # 4469

Q: Has anyone upgrade from platinum to iridium for a Yamaha F225 4 stroke outboard engine? If you have, I'd like to hear comments regarding the change.

I ‘ve been running the iridium plugs in my 2008 Yamaha F225-TXR for three years as I use my bout around 400-500 hours a year, and did not want to have to change plugs every 100hr. I have ran them as many as 250 hr between spark plug changes. If you buy on line you have to make sure they are genuine NGK Spark Plug, cause I bought 1-set of Plug where the boxes looked just like the Official NGK Plug box but they were not! When I changed them out the electrodes were gone. I noticed a big difference when I switched to Iridium plugs the motor runs so smooth that at idle you can’t hear the motor running. You can call NGK and they will cross reference the factory plug to there Iridium plug for your application.

Q: does this item fits nissan teana 2003 and nissan xtrail 2001?

In some regions of the world, the Nissan Teana is also referred to as the Nissan Maxima and in relation to your question my mechanic has advised that YES, these plugs would also fit both the Teana and xtrail. They are also referred to as long-range plugs.

Q: would these fit a ram rebel 2018?? i need 16 don't you sell individually?

NGK 4469 will fit 2018 RAM 1500 5.7L V8. Please use this link for set of 8 (you will need to get 2 sets for 16 plugs) https://www.amazon.com/NGK-LFR5AIX-11-Iridium-Spark-Plug/dp/B01M21CUQA/ref=sr_1_1?dchild=1&keywords=ngk+4469&m=AQNXXK6F2T8SN&qid=1629780442&s=merchant-items&sr=1-1 Also you can use official NGK Website (link below) to verify the application https://ngksparkplugs.com/en/part-finder

Q: are these pre gapped?

NEVER gap iridium or platinum plugs with a normal gap tool. never apply pressure to the central electrode. They should be pre-gapped to .044 in (1.1mm).
