Doubling the oxygen content is a serious proposition. That's like running pure N2O in place of air, and that would burn your engine up without a doubt. Plus, remember that at full throttle and 6000rpm a 2L engine can ingest 100L of air per second. How are you going to store that much oxygen onboard?
An oxygen concentrator is probably too big and heavy to be of practical use like this. However it could be a cheaper substitute for nitrous if you have one plus a compressor. Since oxygen is gaseous you probably can't store as much though.
If you have confidence in your ability to build an oxygen + auxiliary fuel injection system that won't fry your engine then yes, this could be a good way to get a power boost for street or drag racing use. Have a small tank with a tiny O2 concentrator + tiny compressor and store a few liters of oxygen at maybe 5 bar, which is not too dangerous.
