The largest intake available for the Supercharged EA837 3.0T is here.

We recommend pairing this with our 84mm CREC-compatible throttle body upgrade as part of our C7 SuperFlow Intake Package

Following the immense success of our 3.5" Titanium Intake, the market's first 3.5" EA837 intake back in 2017, we decided to take it up a notch. This intake is not for stock throttle body Stage 1 or 2 applications. This massive 102mm intake is a no-holds-barred air-consuming machine for Stage 2+ or Stage 3 ported charger cars running an 82mm throttle body that need the extra CFM to push their build a bit further.

We know what you're thinking: "If my throttle body is 80/82/84mm, isn't a larger intake pointless?"

The key data point here is that while the throttle body has an 82mm internal diameter, the throttle itself is very short in length (under 2.5" to be specific). This means that the pressure drop over an 82mm throttle body is multiplied approximately 6-8x through an 18" long intake tube. With airflow and pressure ratio being such a crucial part of power production in an EA837 engine, we started experimenting with larger intake sizes. 

While monitoring pressure drop at the throttle, we found that our new intake reduced pressure loss, thereby freeing up a bit of top-end power on a ported charger setup with an 82mm TB. We know that for the die-hard performance addict, every 1/10th counts.

This is your 1/10th.

 

Titanium... why?

When developing the world's first 3.5" intake for the EA837 3.0T years back, we knew we had some choices in front of us. The decision to go with CP1 titanium was not one we took lightly. Titanium is not a cheap material to work with, but ignoring the benefits of this aerospace material was not something we could overlook.

Titanium is what we like to call "functionally beautiful". Aside from being one of the most lightweight metals available, titanium has a very low heat transfer rate (16 W/m-K) compared to aluminum (152 W/m K), which means it is highly resistant to heat transfer from the engine bay. Intake temperatures play a key role in power production on the EA837 supercharged engine. While other manufacturers sidestep this issue by powder coating or heat shielding their intake tubes, we opted to go straight to the source by choosing a material that will naturally keep intake temps down.

In addition to its excellent thermal properties, titanium has a much higher strength-to-weight ratio than aluminum, meaning that much thinner tubing can be used in our intakes. This means larger internal diameters when compared to aluminum with the same outer diameter. Our 3.5" titanium intake, as a result, boasts a 5% increase in intake area when compared to a 3.5" aluminum intake. A higher strength-to-weight ratio also means lighter parts.

Our 102mm Omega intake measures in at a staggering 30% increase over our 3.5" titanium intake in terms of inlet area.

Titanium Grade 4, also known as titanium CP1, is the strongest of all commercially pure titanium grades. It combines excellent corrosion resistance with good strength and toughness. This means that your intake will continue to look beautiful well past your engine's expiration date. The lack of paint or powder coating also ensures that the finish will hold up for the long run! Occasional cleaning is all that's required.

Thoughtful Heat Shield Design to Maximize Airflow

We took special care when designing our heat shield/air duct. By increasing the volume in the lower area of the heat shield, we were able to maximize airflow around the filter without compromising heat separation. Our heat shield is designed to mate up perfectly to the edge of the large factory air duct, forcing air directly toward the filter and into the lower pocket of the heat shield, not over it. We further improved airflow by leaving the area under the headlight unobstructed, allowing for two large sources of air into the filter area. The backside of our heat shield didn't go to waste either, providing an improved air channel for the radiator air to pass over the manifolds, cooling the cats/test pipes, and flowing out the bottom of the car as Audi intended.
