True Flow Sealed Air Intake System

True Flow Sealed Air Intake Systems are a unique departure from traditional air intake systems. The factory air box is left intact keeping the airflow cooler while protecting the filter from debris and moisture.  The factory filter is replaced with one of our foam, high flow, lifetime filters.  Finally we eliminate the factory air tube, which can have restrictive mufflers or resonators and replace them with our high flow, powder coated mandrel tubes and reinforced silicone couplers to maximize velocity.  Retains Factory Airbox: Keeps out hot engine air.  Gets cold air from wheel well and protects filter and Keeps all factory hoses and sensors· Proven Performance Gains:

Our Staff can assist you in acquiring the proper filter system for your vehicle. Call and we'll be glad to be of assistance.

True Flow kits are easy to install and maintain. Each kit contains the necessary hardware required to install, (like our custom fiberglass reinforced silicone couplers and stainless steel worm clamps). No modifications are needed, and all factory breathers, sensors and hoses are left intact.

Quick and Easy Install
Power and Efficiency

As experts in aftermarket air intake systems, we often get asked why someone would want to modify their air intake system.  The short answer is better performance, better looks and sound and sometimes better fuel efficiency.  Want more detail? 

Your Air Intake System
Your engine runs on a combination of fuel and air.  The air intake is the system that delivers the air to your engine.  An air intake system is made up of an air filter, air filter housing, and tubing connecting the air filter housing to the engine.  The best air intake system will have the least amount of restrictions deliver cold air to the engine and protect the engine from dirt and debris. 

Since air is one of two parts that make an engine’s power, you would think that automotive manufacturers would optimize the air intake system for performance and fuel efficiency.  While performance and fuel efficiency are important to automotive manufacturers, they must also look at cost and sound when designing the air intake system. 

Automotive manufactures can save money by installing an air filter that is adequate to meet the minimum requirements but not optimal for filtration or performance.  They can also save money by re-using air intake tracts and air filter housing.  You will often see an air intake system originally designed for a six cylinder placed on an eight cylinder engine.  This cost cutting measure can reduce performance and fuel efficiency. 

Many modern day stock air intake systems contain large mufflers and resonating chambers.   They are designed to keep your engine quiet.  They are also a restriction on air flow.  We have seen up to twenty horsepower gains and two mile per hour increases by eliminating these mufflers and resonators.

Which aftermarket air intake is best for my vehicle?
When looking for an aftermarket air intake system you want one that will increase performance and fuel efficiency but continue to protect your engine from dirt and debris.   To evaluate whether an aftermarket is meeting these needs, you should look at all three parts of the air intake system, the air filter, the air filter housing, and the tubing connecting the air filter housing to the engine.

The Air Intake Air Filter
The air filter is designed to protect your engine from dirt and debris.  Dirt and debris ingested in your engine act like sand paper against the cylinder walls.  Over time this will cause a decrease in engine performance and maybe even engine break down.  You can get more detailed information in our filter section, but keep in mind you want a filter that will protect your engine with limited restrictions on air flow.


The Air Filter Housing
The air filter housing is the area that holds your air filter.  Air filter housing comes in three variations:  stock, open element and aftermarket sealed air filter housing.

Stock air intake housings are often a plastic box that seals the air filter.  On the underside of the air box is a hole to let air in and on the upper side of the box is another hole that leads to the intake tube.  In some cases, the stock air box is adequate to provide the protection and air flow you need.  The inlet is set against the wheel well to get non-engine cold air, the air box is sealed to protect the filter from flying dirt and debris, and the air box is designed to provide the engine with plenty of air flow.  In other cases, an aftermarket air intake can replace the stock air box housing to great benefit.

The Air Filter Housing
Most aftermarket air intakes do not have air intake housings.  They are an air filter attached to a “heat shield” and a plastic air intake tube.  While these “open element” style intakes test well on a flow bench, they have two major flaws.

First, an open element air intake does not protect your engine from dirt and debris.  When you clean your engine compartment notice how much dirt accumulates there.  Without a sealed air box all this dirt is hitting your air filter and potentially entering your engine.

Second, an open element air intake is not sealed so it sits in the engine compartment ingesting hot engine air.  Hot air robs a vehicle of horsepower and fuel efficiency.  Fuel combines with oxygen to combust in your engine’s cylinders.  Hot air contains fewer oxygen molecules than cold air.  The colder the air, the more efficient your engine is.  The air filter is sitting in the engine compartment with a useless heat shield. 

The most recent air intake technology uses a sealed system to house the air filter.  A true sealed cold air intake protects the engine from dirt and debris.  It grabs air from away from the engine which limits the hot air ingestion.  Finally, properly designed, a sealed cold air intake will out flow the stock air intake and your engine’s requirements.  This combination will improve performance while providing the protection your engine needs

The Air Intake Tubing
The air intake tubing is the tubing that connects the air filter housing to the turbo or throttle body.  Stock tubing is often stuffed with mufflers and resonators designed to quiet the engine.  You can see great improvement by simply removing these restrictive tubes and replacing them with a smooth aluminum or steel tube. 

Not all aftermarket air intakes give you the best combination of air filter, air filter housing and air intake tubing.  However, a properly designed aftermarket cold air intake can improve your engine’s performance and give you the power, efficiency and protection you need.
