Depending on what state you live in, there are legal measures you can take to legalize your engine swap.

These involve certifying your swapped engine, to ensure that it meets or conforms to your local state emissions.

The EPA deems that any engine swap is illegal when it’s an engine that does not meet this criteria. The specific language behind the legislation refers to any engine swap that “will not consider any modification to a certified configuration to be a violation of federal law if there is a reasonable basis for knowing that emissions are not adversely affected.”

Most Popular Engine Modifications

Hopping up your car has been one of the oldest hobbies for auto enthusiasts. People are always happy with their new car for the first few weeks, but it's only a matter of time before many people are bit with the "mod bug" and want to learn how to make your car faster. Installing engine mods has been a popular pastime for many auto enthusiasts, giving people a fun way to tinker and tweak their cars. Whether your goal is to increase horsepower or to improve fuel economy, there are many engine mods that can help you get the job done.

The engine in your car, truck or van works on four steps or a four cycle combustion process. The engine crankshaft spins your rotating assembly of pistons and rods. As your pistons move down the combustion chamber, it draws in air from your intake through your intake valves. When your engine pistons move back upwards, it pressurizes the atmospheric pressure and your injectors deliver an atomized spray of fuel. Your engine computer then ignites the air fuel mixture to create kinetic energy.

This kinetic combustion of energy is what creates horsepower and drives the crankshaft back around as the process is repeated. If you are interested in learning some of the most popular ways to increase your horsepower, here are some of the best engine mods for your car below.

Air Intake Engine mods

Air Intake Engine mods

Your engine basically acts like a giant air pump, so the best engine mods will always be about moving more air in and out of your engine. Air Intake kits can bolt right up to your throttle body, allowing you to easily increase air flow to your engine in the most efficient manner possible. There are several ways to increase air flow and they generally revolve around these important points about your engine intake.

  • More Air flow - Your stock air intake system is restrictive and made to operate quietly to minimize engine noise. Install a high flow intake filter, or a intake kit to deliver air faster and increase air flow to your engine.
  • Colder Air - The colder your intake air charge, the more dense it becomes which makes for more horsepower generating potential. When your intake temperatures are warmer the conditions for your engine to run efficiently is less than ideal. Cold air intake kits relocate your air filter to a colder area, usually outside of your engine bay or by using a air intake heat shield. Install a cold air intake kit to lower your air temperature and your engine will love you for it!

For most state legislation and exhaust laws however, SEMA’s established standard of 95dB is the guideline. This maximum sound output rating is used for most sport compact applications, and adhered to by aftermarket exhaust manufacturers. If this sounds confusing here’s a quick rundown of exhaust legality facts if you are wondering what makes your car mods legal.

  • Exhaust must remain similar to factory exhaust
  • Exhaust system must not exceed 95dB

How low is too low?

One of the more frustrating fix it tickets you could ever receive is for ground clearance. This is also known as Section 24008 of the California Vehicle Code. This deals with the clearance of your vehicle, and it stipulates that no part of your vehicle can be lower to the ground than the distance between the bottom of your rim.

If that’s not enough there’s also Section 24400 of the California Vehicle Code that states the middle of a vehicle’s headlight cannot be lower than 22 inches from the ground. If you’ve recently gotten a ticket for being too low, it’s a situation that can be remedied through the use of adjustable coilovers.

In many other states outside of California however, this is purely a judgement call. If you live in a state that does not have these specific requirements to how low your car can go, it’s up to the officer to decide. Your suspension isn’t one that most people think about when considering what makes your car mods legal, but it’s an important factor.

Are my HID car mods legal?

High Intensity Discharge or HID light conversion kits were all the rage a few years ago, and today they are cheaper and easier than ever to install. However that doesn’t make all HID car mods legal. In fact according to the Federal Motor Vehicle Safety Standard (FMVSS) Number 108, most HID kits are in fact not legal for street use.

Most people simply slap in a HID kit into their vehicle with reflective halogen style headlight housings. This not only creates a dangerous driving condition by blinding oncoming traffic but it actually decreases your visibility. That’s because the HID kit you are installing is meant for a projector style of headlight, which carefully aims the beam for optimum performance.

If you’ve haphazardly installed just the basic HID kit into your vehicle, chances are your HID car mod is not legal. Make the change to a projector style headlamp or convert to HID properly to make sure that your HID car mods legal.
