⚙️ SRM Production Update – October 2025
Our LPFP systems, A2A intercooler kits, and Port Injection kits for the 4.0TFSI are on temporary hold until November 2025 due to high demand.
We’re short-staffed right now and focusing on fulfilling existing orders first ✅
We won’t compromise quality by rushing or putting untrained new hires on critical assembly.
New orders are still open, but shipping for these parts will resume in November.
👉 Most other SRM products are in stock and shipping normally.
If you’re unsure about availability, please check with us before ordering.
We appreciate everyone’s patience and support 🙏
We’re working hard to catch up while keeping SRM quality exactly where it should be.

Our industry leading Port Injection system that has been fueling 1000HP+ RS7's on E85 for years is now available with spacer plates for cars without our A2A setup. Bringing you the best port injection system on the market at the lowest price ever.

This setup in different iterations has been in development for years. Other PI setups with inferior control technology take out intake manifolds and struggle with per cylinder fuel distribution. We have tested this on our cars so we don't have to test it on yours. Don't be a guinea pig!

You guys demanded it, so we listened and answered. We have updated our website to include aftermarket manifold options for most popular turbocharger upgrades for the 4.0T including Xona's and TS2, as well as the full range of stock turbine turbochargers like our +4mm's and the TS1 as well as RS7 stock size. Get yours while you can.

Happy Holidays!

SRM is proud to announce another piece of the puzzle for driving the platform forward and uncorking the performance of the 4.0T engine.

After much testing and iteration we are making available to the public our drop in turbine housing and upgraded exhaust manifold setup that has already been setting records on some of the fastest 4.0T cars you see today.

These have been putting up numbers for some time now behind the scenes and we are excited to share them with everyone.

Check out the product description on our website for more details about why these make so much more power, why they alleviate the cylinder 5 misfire issue, and why you need them if you want to make real power on your 4.0T.

Thank you to all of our customers for making this possible.
