Opened up my new 2.9 whipple and saw this sticker. I thought it was funny considering I'll be running the car on the corn but I understand that the sticker is for the tuned kits from whipple.
if you're gonna put it on your car i'd say inside the fuel door......but i don't know why you wouldn't just throw it away. The only way it'd spark a conversation would be if someone saw you filling up at the station and saw the sticker, but you don't even fill up at the station....just put it on your laptop or something
