[FXchris305]

hey guys i have to replace my spark plugs but im not sure which ones to get . i would like to just purchase the factory ones . i dont have many engine modz .all i got is a k&n drop in and imma install a z tube when i change the plugs . which plugs do the factory use ?

 

[k3fir]

why do u need to change em? for the sake of fuel efficiency?

 

[FXchris305]

naw ive never change them before . they have 47k miles on them . n itll help the overall performance a lil .

 

[k3fir]

are you doing it yourself? cause i heard they are not just plug n play. if so - make a DIY for us! i think i might need those too.. hom much are we looking at?

considering I drive back and froth to school in PA, and drive a lot for work and stuff in the summer, and my GF goes to a diff. school and lives in PA, I put miles on, they are mostly highway.

 

[fxlr8]

looked in the manual

 

[FXchris305]

thanks so much jeff . it says .43 and on sparkplugs.com it says .44 . does that .01 matter ?

You really don't need to replace the plugs until after 100k miles. The OEM NGK platinum plugs are good for 100k.

thanks doc, that cleared it up for me as well as i am on 79,000 right now..
