Product Guide

The Borgwarner K03 / K04 Turbo Blanket by Funk Motorsport are made from the highest quality materials and are available for all turbo applications. This blanket is specific to the K03 / K04 turbo. Due to the complex shape of these turbos, the blanket represents again a more complex shape than out other blankets and therefore this blanket has been specifically designed for the K03 and K04. This K03 / K04 Turbo blanket not only covers the turbo, but also the exhaust manifold, providing double the heat protection, whereas usually you would have to wrap your exhaust manifold separately.

nDue to the close proximity between the two halves of the turbo, it is extremely common for heat sink to occur. This can decrease performance output while increasing the work of the input components during the combustion cycle. Funk Motorsport Turbo blankets are designed to keep the hot side of your turbo insulated while keeping the cold side at optimum temperatures. This helps to provide cooler airflow to the cooling system and MAF sensor, leading to an increased ignition spark and higher output of energy from combustion. By ensuring that the turbine sector of the turbo remains hot, less heat will be dissipated into the engine bay, ensuring that exhaust gases will flow with less turbulence from the exhaust. See this in action in our video section!

Improve gas flow and increase performance with our Borgwarner K03/K04 turbo blanket. Our Funk Motorsport Borg Warner turbo jackets work to insulate the hot side of the turbo and retain the heat within the exhaust gases themselves. Hotter gases accelerate faster leading to them leaving the system sooner improving spool up and throttle response. Insulating the hot side of your turbo also helps to lower the amount of heat from the turbo that dissipates into the engine bay and intake pipework. A cooler intake results in higher performance and more consistent power figures over time.

A turbo is an absolute furnace within the engine bay. Excess heat produced by the turbo can cause devastation to surrounding sensitive components. Protect anything from oil lines, coolant lines and even bodywork positioned close to the turbo from the dangers of excess heat.

Insulate your Borg Warner K03/K04 turbo to reduce excess heat within your engine bay. Reducing the overall temperature of the engine bay will improve the reliability of electronics, and also help improve the temperature of coolant, fuel and oil lines. From a reliability standpoint, the benefits of a turbo blanket are endless.

While we are on the topic of reliability, what makes a Funk Motorsport turbo blanket the most reliable and durable turbo blanket on the market?

- Specifically developed thread construction to allow for exceptional durability when removal is necessary for routine turbo maintenance. Our new fireproof ultra-high temperature Stainless Steel thread is around 1mm in diameter and can now remain highly durable with temperatures in excess of 1300°C.

- New, thicker internal heat lagging insulation to provide up to 3x improved heat reduction. This insulation wool is created from a ceramic silica complex matting to improve durability over prolonged heat cycles, as well as insulation quantities.

- 4-layer construction for improved reliability.

- Uprated external Carbon Fibre twill and Titanium twill for an improved aesthetic and more durable finish.

- ROHS tested and approved to ensure compliance and desired parameters are reached within our material selection.

You’re in safe hands with a Funk Motorsport Mk3. Turbo Blanket.

Note of caution:
This turbo blanket is not flammable. However, if any flammable fluids are introduced into close proximity of the blanket, the blanket could become a suitable ignition source for a flame to be produced. Please ensure that all necessary precautions are taken in regards to the appropriate maintenance of all oil and fuel lines and fittings surrounding the turbo charger and fuel injection system. Funk Motorsport take no responsibility for fluid contamination our products.

Withstands temperatures of up to 1300 degrees C while offering temperature reductions of up to 90%. Please note: Heat blankets will smoke on initial heat cycles. This is normal. Smoke will disappear after initial heat cycles. Please ensure you read the turbo blanket product guide provided before application.

Have you chosen the correct blanket finish?

Remember: Although 95% of applications do not require an Inside Out blanket, if you have an exhaust clamp, exhaust pipe or similar heat source that will be in direct contact with the outside of the blanket once fitted, you should select the ‘inside out’ finish option.

FAQs

⁠I can’t find my turbo listed, can you help?

Yes! Whilst we may not have every turbo listed, we are confident we have a Turbo Blanket for most. This could generally mean that many turbos utilise the same or very similar blankets to one another. Whilst each turbo can vary in physical size, this is generally only a few mm between frame to frame. These small differences aren’t enough to generally jump up or down a size in Turbo Jacket, since our textiles materials are very versatile.

Get in contact, where we will be more than happy to find the correct turbo blanket for you. If you have any images, or know the A/R of your turbocharger, that always helps to speed up the process too!

What are the differences between Titanium, Carbon Fibre and Inside Out Turbo Blankets?

All three of our blanket finishes feature the same industry-leading construction methods that we are known for here at Funk Motorsport. Titanium and Carbon Fibre Turbo Blankets have a different outer layer for aesthetic purposes, allowing you to choose the best finish to suit the look of your car or engine bay. Titanium and Carbon Fibre Turbo Jackets are designed to have direct heat contact on the inside of the blanket only.

Our Inside Out Blankets however, have a different function and feature the internal material, mirrored on the external face. This is important as our Inside Out Blankets can withstand direct heat contact on both the internal and external faces. This finish offers a solution for those that have a heat source that will rest against the external face of the blanket. This may be an exhaust, oversized exhaust clamp that will touch the outside, or any other external heat contact that could be incurred by incorrect fitment where the blanket is folded over on itself.

It is important to choose the correct Turbo Blanket finish for your application.

Do I need to remove the turbo from the car to fit a Turbo Blanket? ⁠

No! In most cases, Turbo Jackets can be installed on the car, without removal of the turbo. Sometimes people choose to fit Turbo Blankets if they remove their turbo for maintenance, however this is generally not necessary. Some applications will be a little more fiddly than others, however, most can be fitted at home on your driveway! See the Fitting Guide on each Turbo Blanket product page to understand a little more of what is involved when fitting each Turbo Blanket type!

How do I find the Turbo Blanket I need?

We have tried to make this as simple as possible! Either use the Turbo Blanket Finder tool, or search via turbo make, or make/model of your vehicle using the categories that you can find here. Still can’t find what you need? Get in contact, where we will be more than happy to find the correct blanket for you. If you have any images, or know the A/R of your turbo, that always helps to speed up the process too!

Will a Turbo Blanket reduce the life of my turbo?

This is a common misconception. A Turbo Blanket actually separates the turbine housing from the core (in regards to temperature split). This allows the core work with less heat strain on it, meaning that the chance of failure is lower. Importantly, excess heat energy is retained within the exhaust gases. Hotter gases accelerate faster than cooler gases, reducing the overall effect that it would have on the turbo’s life.

Win all around! Lower engine bay temperatures, less heat soak, lower intake temperatures, faster spool up, and more reliable performance! It’s a no brainer.

Any increase in gas temperature happens after the combustion chamber, so wouldn’t have an affect on the combustion process. We understand that a lot of “tuners” get hooked up on EGT numbers, but you have to look at where in the cycle they are being measured. In this instance the temperature of the bang in the combustion chamber will not increase, therefore ruling out all concerns.

⁠Will a Turbo Blanket overheat or ‘cook’ my oil?

No! In fact, a Turbo Jacket will actually help to reduce oil temperatures, and therefore improve cooling! Turbo blankets are thick, and offer protection for the oil feed/drain lines, resulting in a cooler oil entering the turbo, and allowing it doing a more efficient job of cooling the turbo core!

As with any turbo application, to maintain turbo life and reliability, it is recommended the correct turbo cool down procedure is taken after a spirited drive. This procedure is no different when using a Funk Motorsport Turbo Blanket.

What are the benefits of a turbo blanket?

Turbo Blankets are designed to reduce heat output from the hot turbine housing. With the close proximity to the compressor housing, this is key to reducing Air Intake Temperatures (AIT). Lower AITs result in a more consistent power delivery run after run! Turbo Blankets also help to massively create a lower engine bay temperature, providing more efficient conditions for improved oil temperatures, lower fuel temperatures and more reliable electronic components.

The final benefit of a Turbo Jacket, is that the heat energy that is normally lost, is retained within the exhaust gases, creating a faster spool time, and improving flow through the entire exhaust system.
