Vehicles from 1996 and newer do not have a thermostatic air filtration system (TAC) because these vehicles are equipped with second-generation on-board diagnostic (OBDII) computer systems with more sophisticated fuel injection and emissions control systems, eliminating the need for a TAC system. For vehicles originally manufactured without a TAC system, any type of free air filter/intake system can be installed for the aftermarket, as this type of system is not subject to inspection. The TAC system consists of the closed air filter assembly and a thermal housing on the exhaust manifold, then there is also a thermal channel pipe connected to the air filter assembly from the thermal fairing. In addition, some of the TAC systems had a fresh air duct pipe attached to the front or side of the air filter unit at the front or side of the vehicle. If your vehicle was equipped with a TAC system and was removed and replaced with an open air filter/intake unit, the vehicle will not pass the visual emissions component test. Some intake systems we sell from prefixes 63, 69, 77 and RK are not legal in California and other states that enforce CARB emission standards. Please check our website for the specific CARB status of each intake system we sell for a particular vehicle. If the TAC system has been removed and replaced with an aftermarket open air filter/intake system, the system must be approved by C.A.R.B (California Air Resources Board). C.A.R.B. approved systems receive an E.O. (Executive Order) No. And this information is printed on a label that must be placed in a clearly visible place under the hood of the vehicle. I have a 2003 Saab 9-3 2.0t linear.
and I was wondering, if I put the K&N 57I input in my car, will it increase MPG on my car? Some people say that cold air intakes decrease turbo lag, but wouldn`t that cause less MPG? Texas is one of the most forgiving states when it comes to changing the height of your vehicle. There are no laws or restrictions when it comes to lifting kits, electric shock absorbers such as monotube shock absorbers or nitroon shock absorbers, improved wishbones, oversized tires, and front guard bars. Pretty much the sky is the limit with these kinds of modifications. If you are looking for a quality brand, if your dream is to own your own legal monster truck for the street, Texas is where dreams are made. However, you still need to comply with certain guidelines. Any open intake system, such as: A short valve or cold air intake directly affects the amount of emissions emitted by your vehicle Texas law states that any aftermarket air intake system must be C.A.R.B. Vehicles from 1995 or later originally manufactured with a TAC system must be equipped with a closed air filtration system to reduce carbon monoxide and hydrocarbon emissions during cold engine operation. All components must be present to pass the visual inspection of emission components, which is part of the annual safety inspection. When an engine is running, it becomes hot and inefficient. Thus, when cold air is introduced into it, it can cool down and be much stronger, which increases the power. NOTE: If the air intake system says “Race Only” or “Off-Road Use Only”, it is not intended for use on public roads and is not approved for road approval.
While the air intake system is CARB approved and legal in 50 states, it is street legal in all 50 states. All K&N 57 series air intakes for North American vehicles have been assigned CARB OE numbers and are authorized to operate in all 50 states. There is also a thermal channel pipe connected to the air filter assembly from the thermal coating. The TAC system consists of a fresh air duct pipe connected to the front or side of the vehicle from the front or side of the air filtration unit. The TAC system is a closed air cleaner/filter assembly designed to reduce hydrocarbon (HC) and carbon monoxide (CO) emissions during cold engine operation. This admission system is legal for road use in most states. However, it is not legal for sale or road use in California and the aforementioned states that have adopted California emission standards under Section 177 of the Federal Clean Air Act of 1970. Intake systems are subject to regulation by the State of California and certain other states that adopt the emission standards of the California Air Resources Board. For an admission system to be legal for a particular vehicle in California and other adopting states, the part number must be assigned an Executive Order (EO) CARB number. This number makes the part legal only for certain years of manufacture, makes and models of vehicles. A sticker with the OE CARB number for these parts must be affixed to the engine compartment to meet the requirements of the smog inspection. It also depends on the year of your vehicle.
1996 aftermarket air intake systems, or AIS and thermostatic air filters (TAC), and new vehicles do not have a thermostatic air filter or TAC system.
