RIAYOOE 3 3.5 4 inch Cold Air Intake Filter 76mm 89mm 101mm Performance Cone Air Filters Universal for Racing Sport Car 3 Sizes in 1, B-4in-Red (XH-UN078-101-RD)

Worked great. Perfect fit for the space I had. Seems to flow plenty of air

Perfect for my f150

I replaced a SPECTRE filter with this one, and I can tell you a few improvements: - Probably will take more time to rust this time - Way lighter than what I had for the same size - Seems to flow more because the end is not cone but just foam wall (less air turbulence) This filter improved the car's performance compared to the horrid experience with the SPECTRE one before.

It functions as needed. Has an additional air breather on the top, when usually they are sealed in that spot, allowing more air flow.

Works great, love the color and the side decal. Would compare to K&N, great airflow. Good price, very easy to install came with everything needed to do so. Fits my 99’ Chevy Silverado 2500 no problem.
