If you’ve ever tackled a catch can setup or swapped out your PCV system on your VW or Audi, you know that leaving an open port on the intake manifold can be a bit of a headache. That’s where the IE Boost Cap comes into play. This isn’t just any cap; it’s a solid, CNC-machined aluminum piece that’s designed to seal up that leftover port on your 2.0T FSI/TSI or 2.5L 5-cylinder engine.

What I love about this boost cap is how straightforward it is to use. If you've removed the factory PCV system, this cap fits snugly and securely blocks off the intake manifold PCV inlet. It comes with an O-ring for a reliable, leak-free seal, so you can rest easy knowing it’s not going to let any unwanted air in. Plus, installation is a breeze. You won’t need any fancy tools—just pop it on with the factory-style clip, and you’re good to go in seconds. Seriously, it’s that simple.

For those who might want to get a bit more technical, this cap also gives you the option to turn that port into a vacuum tap. This is handy if you’re looking to install a boost gauge or hook up to an engine management system. The kit includes all the hardware you need, whether you’re just blocking off the port or converting it for use.

Here’s a quick rundown of what you’re getting:

  • Compatible with all FSI/TSI 2.0T and 2.5L 5-cylinder engines.
  • Easy installation—no tools required.
  • Crafted from high-quality CNC-machined aluminum.
  • Comes in a sleek black anodized finish that looks great under the hood.
  • Includes an O-ring and securing clip for a hassle-free setup.
  • Threaded plug or vacuum tap options included.

This boost cap fits a wide range of models too, so whether you’re driving an Audi A4 from 2005 to 2015 or a VW Jetta from 2006 to 2014, you’re covered. It’s a small but mighty upgrade that makes a real difference in your engine’s performance and reliability.

In short, if you’re looking to clean up your intake manifold after a PCV delete or just want a reliable way to manage your boost gauge, the IE Boost Cap is a no-brainer. It’s a solid piece of hardware that gets the job done without any fuss.

Who is Integrated Engineering?

Integrated Engineering was founded in 2007 in Salt Lake City, Utah. It was started by two brothers Peter and David Blais. The two shared the same passion for racing, and this has jumpstarted the two to create Integrated Engineering.

As the experts in these platforms, they are able to pinpoint exactly what parts need to be improved to bring out the best in those vehicles. The company considers not only the performance gain but its reliability as well. Their goal is to turn these vehicles into a better performing machine without compromising its reliability.

Attention to Detail is the Key

To create top quality products, the company carefully studies each design detail using specialized software. This enables them to fine-tune the design before it goes to actual manufacturing. They first test their design in ABS plastic to ensure that all measurements are accurate and on the spot. Once everything has been checked, their performance products are then tested in their in-house engine and chassis dyno machine for long hours to test its performance and reliability.

This attention to detail has enabled their parts to perform in extreme conditions and withstand the punishment usually endured during high-performance applications.
