cold air intake + hydroshield question?
Cold Air Intake Hydro Shield
Please don't waste your money on that crap. First off, the cold air intake is worthless and you plan to spend more money to protect it with another scam, the hydroshield. The best air intake for your car is the one that was designed for your car by the manufacturer. After market cold air intakes are nothing but a scam. They do absolutely nothing positive for your car except make it sound different. Cold air intakes don't work because your fuel and air mixture is controlled by the car computer and any change to the stock intake will result in problems with your engine sensors. The computer will see any change to the intake as a problem to correct by attempting to adjust the fuel / air mixture to the original factory settings that it was programmed to maintain.
Those things help if your intake is sucking little water, but if the cone filter is flooded with water then your car will be high risk in hydrolocking if thats your concern. Even with this on if you drive fast over puddles or your cone filter gets soaked with water you can still hydrolock your motor So its not really much insurance. If you need to buy one, the shields are based on the size your filter most common is 3- 3.5in cone filters, you would have to measure it if you dont know.
