all i can say is, i went with the cp-e because they are a research and development company and their intake is made specifically for this car in house from scratch and has been engineered under real world testing situations. I have had mine for about 9 months and never has my MAF given me any trouble. also, speaking of the MAF housing/location, cp-e has stepped down the diameter of the piping near this sensor in order to get the most accurate reading while keeping in mind the integrity of the vehicle meaning zero check engine lights, not to mention the design simplicity and uniformity of this intake which is just one whole piece and not multiple junctions.
