  1. HP Stealth Shield™ Heat Barrier Test

    HP Stealth Shield™ Heat Barrier Test

    Keeping heat out of your car or truck’s interior can make the ride a lot more enjoyable. Heatshield Products thermal barriers, insulation and other heat control products significantly decrease the heat transferred to the interior of the vehicle. To show what our product line is capable of and what you can expect, we conducted a test using the HP Stealth Shield™ heat shield interior insulation and thermal-barrier material.

    HP Stealth Shield is a lightweight material that feels like felt cloth and is based on the same proprietary technology and specially formulated material used in our welding blankets. It blocks heat and can even withstand direct contact with flames. At

    Sticky Shield and Stealth Shield Floor Pan Heat Simulation

    Heat rises. Always has, always will. It’s one of those physics things that’s indisputable and constant in the universe. It’s also why the heat from the exhaust system on a car or truck will always radiate upward. As that heat goes up, it hits the floorboard, then is transferred to the interior, which increases the amount of heat that the air conditioning system (if the vehicle has A/C) has to deal with – not to mention it’s felt by the feet, legs and even rearend of passengers.

    Heatshield Products has multiple products that can reduce this heat, including our Heatshield Armor exhaust insulation. We know that some people don’t want to put anything on th

  3. Use Thermal Barriers to Prevent Vapor Lock

    Whether your vehicle has a carburetor or fuel injection, vapor lock can bring it to a standstill, causing hours of frustration. If you’re a racer, it can put the car on the trailer well before you’re ready to leave the track. But proper use of thermal barriers can prevent vapor lock, no matter how hot the day gets.

    Vapor lock happens when the temperature of the fuel heats up enough to transform it from liquid to vapor. And since fuel pumps are designed to pump liquid, not air, vapor lock effectively starves the engine of fuel. Without the proper volume or pressure of fuel, the car will run rough or completely stall. Vapor lock typically happens during summer months, when high outdoor temperatures are combined with high engine and exhaust heat. And high altitude also makes a vehicle more prone to vapor lock.

    The solution is to protect the fuel lines from getting hot in the first place.

    For carb-equipped vehicles, one of the easiest solutions is to use a t

  4. Keeping Your Airbox Cooler Using Heatshield Products

    When it comes to performance, cool air is one of the largest contributing factors. Cooler air is more dense meaning that more oxygen is sucked into the cylinders during induction. The more air in the cylinders, the more power an engine can make. With fuel injected engines, cool air also affects how the computer controls the ignition system (that’s where cold air intake heat shields come into play but we’ll get to that later!)

    All modern fuel injected engines have air intake temperature sensors. With these sensors, the temperature of the air entering the engine is measured, and the ECM then makes the necessary adjustments to ignition timing, air/fuel ratio, and more to keep the engine operating within its set parameters. As you can imagine, warm air effects this measurement. When air intake temps get too warm and there’s a risk of detonation, the ECM will reduce ignition timing to gu

  5. Keep Fuel Rails Cooler and Make More Power with FR Shields

    How to Keep Fuel Rails Cooler and Make More Power with FR Shields

    At Heatshield Products, we’re big proponents of automotive heat shields and fuel line insulation. Fuel rails see a lot of exposure to radiated heat since they sit atop the engine, plus small engine compartments mean less airflow to help move heat out. Lower-profile hood lines and factory engine covers on modern cars c

Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment.
