I have an 08 FX4 and I am changing plugs this month. I am looking at the NGK Double Platinum 1 Piece Plugs (CHA 7989 part Number). Does anyone have experience with these?

If not those, what would be a good alternative to the stockers? I believe that I have a 2 piece design in there right now, and I am all set-up to take them out...I just need to order a new set of plugs.

Please include part numbers and maybe a "cheap" place to get them from. I know that I will be spending $100 bucks, and I am okay with that...I just need to get them done! Any help is appreciated!
Thanks in advance!

 

What month of 08 was your truck made in?Depending on which month,you might have the one piece plugs as ford went back to the one piece plugs in the 08's.Wish i could help you on the plugs that your looking at,but dont have them installed in my truck,I have the brisk plugs in mine and have made a world of diference in my truck

 

Mine was born in Jan of 08. What part number are your Brisk ones? I was looking at them too...

 

Ya you got the 2piece ones.Here ya go man.Total with shipping i payed about $165.00.

SKULL31- can you tell me the month they changed plugs in 2008? im curious when they went back to the one peice plug.... thanks

 

If i remember correctly it was july/august time frame.You afraid you got the 2piece plugs in yours?

 

So if my build date is Aug 07 then i have the two piece?????

 

Yes yo do.I did my friends 07 FX4 and he had the 2piece plugs and changed them over to the Denso one piece plugs.Personally i think he got ripped off,but thats neither here nor their,lol.You thinking of getting your plugs changed out?

 

i am thinkin about doin it..but my truck is an 08(kinda wishing i had the 1 piece) i think i'll wait until i save a lil bit more $$$$$

 

I'm not sure, where can I find the build date? Or what Lind of plug are the two peice?
