Where can I get this stuff... I am putting on headers...and dual exhaust over Labor day...I will be doing a cam swap the next weekend...I figure I'll do some GM top end engine cleaner with the Headers...and an oil change....then it will be good and clean for my cam....( MTI X1 )....
so where do I get this stuff....

 

Most GM dealership parts departments carry it. Make sure you get the aresol can version so you can jsut spray it into the throttle body while the car idles .
