Cold Air intake plays a important role in vehicle performance level.

Basically the purpose of Air Intake is to deliver right amount of air into engine. Cold air intake sucked cold air and mix it with fuel, burnt and exhausted. And as the density of cold air is much higher than of hot air, cold air brings more oxygen and makes more power.

You will see improved performance with more horsepower, acceleration and gas mileage along with good sound by using cold air intake in your vehicle.

This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range.

The air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the original air box space.

Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body and turbo inlet for a guaranteed power gain.

The tube accommodates the factory air temperature sensor. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions.

This air intake is relatively easy to install, usually in 90 minutes or less using your vehicle’s existing factory mounting points. The tools needed are a screwdriver and an Allen wrench.

So, without wasting more time let’s move towards the bonus Upgrades.

#1 Increase HP & Overall Performance with Intercooler Kit or heat Exchanger 

An intercooler, or “charge-air cooler”, is an air-to-air or air-to-liquid heat exchange device used on turbocharged and supercharged (forced induction) internal combustion engines to improve their volumetric efficiency by increasing intake air-charge density through isochoric cooling.

heat exchanger for Chevy Silverado 1500

Here we’re talking about heat exchanger which is basically a intercooler only. Basically, Heat Exchanger uses air from the atmosphere, flowing over and around a lot of finned tubes to remove heat from the intake air charge which means it reduce the temperature of the air that has been pressurized by the supercharger/turbocharger that is going through the intake tubes.

In layman terms, a heat exchanger is a device designed to efficiently transfer or “exchange” heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air.

Check inter-cooler for GM Models

When you use air-to- air heat exchanger, cooler air will be directed towards the tubes that will maximise the cooling effect and ultimately create impact on the performance of the vehicle.

So, upgrade your GM truck with universal fit Edelbrock HEAT EXCHANGER. You can choose as per your truck specification and other measurement details.

#2 Upgrade with Intercooler Piping Kit (50% Better Air Flow)

And, if you’re looking to upgrade your truck with all new Intercooler kit then there is no other better option than CXRacing Intercooler Piping Kit that comes with 50% larger intercooler core offering much better Air flow and cooling capacity then stock.

You will get nice increase in fuel economy while improving overall Engine performance and It also lowers EGTs.

It is not wrong to say that using Heat Exchanger instead of full intercooler kit is more convenient way to increase performance as buying full kit will definitely cut your pocket but if you’re looking to get that astounding amount of power then you have to compromise with your pocket and go for the kit.

#3 Outflow Factory intercooler tubes with aFe Intercooler Tubes 46-20334-B Add up to 38% more airflow

If you don’t want to hit your pockets then you can also go with aFe Intercooler Tubes Hot and Cold Side 46-20334-B for Your GM Trucks 17-19 V8-6.6L that is made to increase overall performance by outflowing the factory tubes up to 38%.

The high quality aluminised tube are mandrel bent and powder coated to Offer maximum flow and performance. The bends are perfectly made to decrease turbulence and minimize pressure loss while increasing HP and Torque.

Moreover, the I/C tube kit transfers hot air smoothly to the intercooler to accelerate heat transfer then cooled air to the engine to help make more power.

Easy to fit and featuring quick installation, the kit tubing comes in wrinkly-black powder coating with badge engraved on it giving it impressive appealing look.

This can easily be fit on 2017-2019 GM L5P diesel trucks models.

#4 Diesel Fuel Filtration system for GM Trucks 

We all know, the fuel in the truck contains contaminants dirt, water and air/vapour that is reducing power and damaging the diesel fuel injectors.

To resolve this problem, Afe comes with Fuel Filtration and Air Water Separation system for GM trucks that will completely uproot the contaminants from the fuel.

It will improve quality of diesel fuel and make your engine run more smoothly and efficiently.

It will basically remove or separate the entrapped air from your diesel fuel while improving the pressure and flow to your Duramax. It will also add additional filtration to deliver clean and pure fuel that will increase performance and reduce injector wear.

Not only this, it will also protect your fuel from dust intrusion and powerful water jets.

Easy to install, the system comes in several different models and available for vehicle-specific kit. Moreover, there is no need of cutting or drilling or modifying the fuel tank to install it.

You just have to attach harness (that comes with kit) to the battery and utilizes Deutsch weather-proof connectors for plug-n-play installation.

Comes with limited lifetime warranty, the system supports up to 1 Micron Filtration. So can easily imagine the quality of fuel fed to your engine.

We personally like this system, as this system is one of the best of its kind that will remove all the impurities and give your engine clean and pure fuel. It’s like, if you’re eating pure and healthy food you will definitely boost up with lots of energy. Same way engine works.

Bu using the pure fuel, the engine will work more efficiently and gives better results in form of increased HP, torque and overall better performance.

So why waiting!! Upgrade your vehicle with all new Diesel Filtration and Air-water separation system for increase engine efficiency and performance.

Note: Compatible with diesel and biodiesel fuels.

#5 Fuel management or Throttle Optimizer for your GM Trucks

Performance mode (where throttle is adjusted to obtain maximum performance or economy with less response) , Tow Mode (where throttle is adjusted for maximum performance and response) and last is, Off-Road Mode ( where more power and acceleration part is considered while adjusting throttle).

#6 Spring Booster for Improved Drivability

If you’re looking to improve drivability without putting any extra tuning mods, then The Sprint Booster is a perfect alternative for you!

The best thing about this upgrade is -you can easily use it with or without other tuners/programmers due to its ability to work independently from other modifications.

Sprint Booster for Chevy Silverado

Basically Sprint Booster modifies the signal between the accelerator pedal module and the ECU. The improved signal encourages the throttle to open “more” than what the stock signal was providing at a given pedal position. The end result is the idle-to-full-throttle pedal travel is reduced.

Also Check other Throttle Response Controller for your GM HD trucks

Sprint Booster basically makes your truck “feel” more powerful because the given pedal input produces greater throttle opening.

Easy and quick installation, this performance mod is one of the perfect and effective upgradation for your truck.
