UNI Foam Pod Air Filter – GY6 / PWK / CVK / Polini (Multiple Sizes)

The Details ⚙️

Looking to ditch the restrictive stock airbox and let your engine breathe? These UNI foam pod filters are one of the easiest and most effective airflow upgrades you can make.

More airflow = better throttle response, improved performance, and a cleaner overall setup. Whether you're running a stock carb or a full performance build, this is a simple upgrade that makes a real difference.

Each size is designed to match specific carburetors — just pick the one that matches your intake diameter and you're set.

Why UNI filters?
• High-quality foam filtration
• Better airflow vs stock airbox
• Reusable and cleanable
• Proven performance across scooter and small engine builds

Simple upgrade, real results 🔥

Which Size Should I Pick? 🤔

• 1.5" (44mm) – Straight: Stock GY6 CVK carburetors, most Ruckus/Metro GY6 swaps
• 1.75" (~45–46mm) – Angled: PWK / OKO carburetors or builds with tighter clearance
• 2" (50mm) – Angled: Polini CP carburetors and larger performance carbs

The 1.5" filter is straight, while the larger sizes are angled to help with frame and shock clearance.

If you're unsure, measure the outer diameter of your carburetor inlet or message us — we’ll point you to the right one.

Picking the correct size is critical for proper fitment 👍
