Mine has the orange hue on everything, the NGK plugs have 10,000km with no issue and 8 cans of boostane through them. The MMT that coats everything in orange used to be the go to octane booster than refiners used in the 90s. My exhaust isn't showing the orange but I recently upgraded to Remus so I only have 5,000km on it. I started reducing the amount of boostane I'm using to 1/4-1/8 of a can since I stopped trying to run the 93 OTS map.
