It's an air filter. Works as it should. Rather expensive but I prefer this over the other cheaper aftermarket brands that need to be oiled and cleaned more often. Feels sturdy and of good quality - way better than anything store bought. Good buy.

Replaced a Spectre oiled filter on my short ram. Didn't expect much of a difference, but my turbo breathes better now. Good product.

I purchased this air filter in particular because it is a dry filter. Many fuel injected cars rely on a mass airflow sensor to measure the amount of air coming into the engine. Other cone filters (K&N, etc) are oiled to trap dust. The oil droplets will accumulate on the sensor and eventually ruin the sensor.I have not yet had to clean this filter, but it is supposed to be much easier than the oiled filters. In addition this filter looks great in the engine bay. I'd post a picture if I could.

AEM filters are the best out there, no oiling required and they hold up amazingly over time.

Fits tight in the K&N CAI for the Kia Telluride, but this is the closest size to the K&N filter the CAI came with.

Return never filed, filter is WAY too small for large trucks. Difficult transaction all around.

The filter works great. Good quality and well-made. I would buy again.

Be sure to check the size of your intake before buying your filter.. Changing the filter at the right interval is key to maximizing the performance of your vehicle. Definitely a noticeable difference when you change your filter and I love the bang for your buck on this product.
