This stuffed up my car. Through a catalytic converter code po420
I regret not ordering more of this new octane booster even though I like it.
Adds to fuel efficiency
The K&N Octane Booster works very well. I added a bottle to my tuned Stinger GT and data logged while driving around. I gained some timing at max boost and the engine felt smoother. Would recommend
execellent product recommend it to any car person .
