naw thats crazy . 100k miles ? il change every like 50k the most 60k. yea when it reaches 100k the car wont start cause the plugs are so bad but to keep it running good you gotta replace them sooner . especially if your gassing it everyonce in a while .
 
I replaced mine at about 15k miles to the NGK iridium one step colder and I have had no problems now at 92k miles. Just pointing out that the platinum plugs are meant to last much longer than your normal type plugs. The iridium and platinum plugs are meant to last.
 
Can someone confirmed that "...OEM NGK PLATINUM plugs..." is true? So, the OEM plugs are already platinum plugs, right?? If so, why changing before 50k at all??

I had the hks twin power until it broke, fried a coil and made my car misfire.. Took it off and everything worked fine.

i changed my plugs at 70k and put in ngk iridium's (LFR5AIX-11). and yes, there was no doubt in my mind after looking at the old ones that the o.e. plugs would have made it to 100k with no problems. i just changed them for my own piece of mind. and it wasnt difficult at all.
 
Agree.. Pulstart are good spark plugs.. Can't complaint.. Being having them for over 8k and still show good mpg everytime I drive my FX at the speed limit( barely happenned)lol
 
planning on installing new plugs tomorrow... will try to post a DIY... my boy who painted my RIMS suggested i change them to improve performance:confused:
