Installing Aftermarket Parts: I want to install some aftermarket performance parts on my car's engine but I'm worried I might have a problem passing the CA smog check. I want to install a turbo unit, air intake unit, and exhaust headers. How can I find out if the upgrade parts I want to use are California smog legal, and won't fail the emissions test? What about OEM parts? What You Must Have: Engine performance upgrade components such as upgrade ECU, turbo units, exhaust headers, intake manifolds, and other emissions related components can pose smog check problems, however if proof is shown that the upgrade units are legal for use in California (they posses an EO number) or they are OEM parts, they will not cause a vehicle to fail the California smog check. EO stands for Executive Order. This is a number given to the emission upgrade component by the California Air Resources Board (CARB). The EO number indicates the performance upgrade part is California emissions legal. Most manufactures of aftermarket performance parts will stamp the EO number on the unit or they will print in the unit's manual or other document which pertains directly to the performance upgrade component being installed or inspected.

Most late model upgrade components however will have the EO number stamped on the upgrade parts body. You must present this number to the smog station where your vehicle will be getting a smog check in order to pass the visual portion of the smog inspection. Which Parts Are Smog Legal? Aftermarket engine upgrade components sold at local California automotive part stores are CARB approved and posses EO numbers. Buying an upgrade component locally in California is a safe method of performing engine upgrades. Performance upgrade components bought online or out-of-state might require a little bit of leg work to ensure they will not cause a California smog check failure. A non-emission related component does not need an EO number. A typically non-emission related upgrade component is the air filter unit.Air filter units which do not have any sensors on them and allow for the proper connection of all existing air intake hoses and vacuum lines are not considered emission components in most cases.

Manufacturers often produce components that are purchased by a company and retailed under the purchasing company's name.

When referring to automotive performance or upgrade parts, OEM designates a replacement component made by the manufacturer of the original component.Installing OEM parts often protect a vehicle's warranty and will ensure your vehicle does not fail the smog check for an emissions system tamper. Using OEM parts is always recommended. Added on: October 13, 2014 Follow us on Instagram..

How Much Horsepower Will My Mustang Gain From A Cold Air Intake? Mustang Ram Air Intakes Mustang Cold Air Intakes (CAI) Vs Ram Air Intakes (RAI) Do I Need to Tune my Mustang if I Upgrade my Cold Air Intake? Shop Mustang Air Intakes Replacing your restrictive stock air intake is an essential mod for all Mustang owners. By allowing more airflow you will see better gas mileage and improved performance, as well as better throttle response. Understand the difference between a cold air intake and a ram air intake for your Mustang, so you can choose the one that offers you the performance you want. The stock intake system was designed to be the quietest piece in the engine compartment. This is great for the driver because it decreases the amount of noise being put out, but it comes with a price. The location of the stock intake in the engine compartment means that the Mustang isn’t running as efficiently as it could be. There's a number of ways you can upgrade your pony's intake system, so never fear.

But first there some things to cover.Hot air is less dense than cold air and limits powerAftermarket filters are useable and cleanable while being more efficient than the stock filterAftermarket tubes provide a more direct path for incoming airCold air and ram air intakes are two options each with their own pros and consAdding on a tune along with an intake will net more gains, but are not always necessary If you’ve ever put your hand near a running or recently turned off engine, you know how hot they get. Now imagine that heat running through your stock air intake, into your engine, and through your exhaust pipes. Not a very nice picture, is it? The stock tube has a number of bends and turns, so the air doesn’t flow as freely as it could. The air itself is also heated by the engine which reduces its volume. The result is a less than ideal mixture in the combustion chamber. The further from maximum efficiency the mixture is, the bigger the decrease in power.Replacing your stock intake with an aftermarket cold air intake (CAI) will take care of these issues by:Relocating the air box from the engine compartment to the wheel well, so cooler air is being drawn inThe larger intake tube increases volume of air being drawn into the combustion chamber, which allows for better burn.

Better burn means more powerThe shape of the tube allows air to take a more direct routeThe air filter is higher quality and less restrictive Air FilterUsually conical in shape, with grooves and folds. Some of the benefits of an aftermarket performance filter include:Although smaller than the factory filter, it has more surface area which allows air to be drawn in from every directionMost aftermarket filters are reusable, and only need cleaning every 30,000 to 50,000 miles. The stock air filter needs to be changed every 15,000 miles, and must be thrown awayAftermarket filters draw in a higher volume of clean, cool air. Expect more power, improved acceleration, and even better gas mileageIntake TubesSpecially designed to straighten air flow as much as possible, while looking good in your engine compartmentAftermarket pipes are typically mandrel-bent so there is no crimping of the pipe diameter at the bend The question on everyone's mind is how much horsepower you'll gain from swapping your stock intake for an aftermarket one.

There are manufacturer's that will promise a gain of 15-20 hp, but that's a bit of a stretch. The typical power increase is 5-10 hp Much like a cold air intake, a ram air intake (RAI) pulls in cooler air from outside the engine compartment. Unlike a CAI, though, the Ram Air on a Mustang uses a shorter tube, which causes the air to be pushed into the throttle body with much greater force. There is a larger volume of air which, in turn, leads to more engine power.As you increase the speed of your Mustang, wind pressure is forced through the intake manifold and filter. It’s almost like having a turbo charger, but without the additional parts. The downside to the Ram Air is that it will not be very noticeable until you are traveling more than 35 miles per hour.​Other than those differences, the Ram Air Intake is the same as a cold air intake. The power gains are also similar at a typical increase of 5 - 10 hp with a ram air intake. Here is a quick Pros & Cons list to help you decide which is better for your mustang.

Ram Air Intake:Also known as a Short ram intake. This type of intake uses the straightest possible tubing with a large filter with heat shield to get the maximum air flow. Does not go into the fenderwell.Pros: Pulls in more air, usually cheaper due to less piping.Cons: Air pulled in is warm from the engine compartment.Cold Air Intake:Uses a curved pipe to go in and sometimes down the inside of the fender to pull in air that is not heated by the engine. Uses a smaller filter than a Ram Air Intake and will not pull in the same volume of air as the Ram Air Intake.The design of the cold air intake relocates the air filter to the coldest part of the engine compartment or through the inner fender to the wheel well. This allows the intake to pull colder, denser air into the motor. By pulling the colder air, combustion efficiency is increased, and in turn, creates more power. An added benefit of the efficiency in some cases is increased fuel mileage (typically 1-2 mpg).Pros: Pulls in cold air for better combustion.
