Does any one know where you can get a GReddy plugs from?

My G/Fs little bro got a stiker for me to put on my car, so rather than be a ba$tard and tell him to get F**k*d i stuck it on my car, And rather than fell like a tool havin the sticker for no reason i want to go out and get some or a part/s to justify it my self. Plugs, from what i know of are the cheapest/effective parts for an N/A Magna in the GReedy stock (other than the sticker)

you could always get an oil or radiator cap.....

lol I dont think that would really help with the mental anguise in stuffering
