this all goes with the maturity of the driver, you dont use nitrous every day, u use it on your cruise nights, pull the rabbit out of the hat when that other faster car cant figure out why u drilled him. if you run a 3 bottles a month thru your car, its bad news. the occational useage will not harm your engine, its the abuse that always leads to engine failure. if you LEARN and RESPECT what this will do for your car you will enjoy many years of bottled fun.

cliffs:
nitrous oxide = bigger explosion in cylinder
bigger explosion in cylinder = more power
bigger explosion in cylinder also = more stress on cylinder walls
more stress on cylinder walls = greater chance for engine failure
the only BMW owners i see thinking about NOS on their car are the 16-20 year olds whos daddy and mommy bought them their car...
either that or someone extremely rich who has money up his ass to blow
i dont see anyone putting an unsafe mod (unsafe compared to other performance mods out there) on their 40,000 car that they worked so hard to be able to have.
