i sell it for 20.79 (23.70 with taxes) cdn $but you should be able to find it at an auto parts store down there...just ask if the stores sell blue streak (standard) and the part # is vg57, parts are always way cheaper in the states...but if you can't find it shoot me a message...or just post on here

check you big name stores like autozone and them...i dont know if they carry them, but if you have a store down there called auto plus or auto parts plus...or even carquest all carry blue streak..i dont have good luck with carquest stores...the guy that runs the one up here isn't to greatest guy to deal with..

i've heard people telling me they're like 10 bucks in the states..just dont know where they got them from

 

To answer what the EGR question is, one of the best learning devices I used was a Haynes manual. Is showes tons of location and pictures of what parts look like including some basic wireing schematics and specifications.

 

EGR is expensive 200-300 cdn. l checked mine last night was not plugged. l guess l will have to get the code run.
