You must evaluate your current driving conditions. For example do you use your vehicle as a daily driver? How much of a difference do you think a few horsepower will make? If these are things you desire then I would say get the high flow airfilter. However I do agree that more air flow = more dirt. No air filter will ever filter 100% of the dirt coming in. I personally would stick with the stock airfilter. A few horsepower to me is not worth it. Remember toyota engineers designed the whole system to provide years of reliable service.
