K&N filters are typically the worst for filtration(or very near the bottom), they gain performance by sacrificing filtration:
If you can sit down and take the time to read the whole article it has some very interesting information(or just skip to the end for the conclusion).
I don't know about a more "efficient" delivery method, the stock airbox is already a "cold air" intake.........Adding a K&N kit like you mentioned wont change that, and will give you a filter with lesser filtration properties.......but with the benefit of being freer flowing for performance.
Of course if your willing to compromise air filtration for performance why not just remove the filter completely? Thats way cheaper and its going to flow the best out of all options.......once again at the complete loss of filtration.
