Product Description

This bolt-in airbox window is designed for owners running Z1’s first-generation cold air intakes who want the same upgraded window system featured on the newest kits.

The payoff is a cleaner look, a better seal, and more confidence when the terrain and weather are wet.

Why Upgrade?

The original gasket-style window provided a solid seal for everyday use, but this bolt-in window design raises the bar. By fastening directly to the airbox, the window maintains a more uniform seal that is better suited for demanding conditions. Access is still simple, and reinstalling the window is just as straightforward. A dedicated gasket between the window and airbox adds another layer of protection while preserving the clean, factory-style fit. The kit also includes an improved filter grommet that creates a more precise seal around the intake tube and airbox. This refinement helps further reduce the chance of moisture or debris finding its way in, especially when the vehicle sees off-road use or wet environments.

Snorkel Owners Take Note

If you are running a snorkel, this upgrade becomes even more valuable. By tightening up potential airbox leak points, it supports better water fording capability with reduced risk of water creeping into the intake system. Trust us, water belongs on the outside.

Features:

  • Upgrades older Z1 cold air intakes to the latest bolt-in window design
  • Dedicated window gasket ensures strong and secure seal
  • Even more effective when paired with a snorkel
  • Simple removal and installation
  • Improved filter grommet for a tighter and cleaner intake tube seal

Compatible with the following Z1 Cold Air Intakes:

The crew was great in solving the issue with my airbox ( since I've had it since it came out ) third revision and spot on the high quality you'd expect....has been great since I installed it and not very difficult to install

Awesome! Easy install without any trimming. Definitely feel more confident in this seal. I did have the original window pull inside the airbox a couple times with a snorkel when revving the engine. Thanks for an affordable upgrade!

This is getting a four-star review because it came out literally a day or so after I got my cold air intake from Z1. That's it I can't say that this is a nice upgrade. For some reason it made the intake a little bit quieter and at the same time allowed the air to flow a little bit more. The seals don't cover the air filter as much and help ensure that you got a nice tight seal around the airbox especially if you're one who likes to head on the trail and ford water.

Finally! Saw this at the open house and have been waiting for it. Easy bolt-in upgrade that addresses the biggest annoyances with the early model intakes.

I had bought my intake in ‘24 before the upgrade and now that I have upgraded with this kit, it’s definitely more water tight and gives me more confidence to trudge in water!
