looks amazing
Easy to install, clean, and looks incredible. The color is bright and elegant. It fits perfectly, is efficient, and improves the air entering my truck's combustion system.

Great looking shield!
Nice shield for the intake. My only concern is the length of the screws with the vibration, they would need to be retightened often. Make sure you look flush the breaker to the hose clamp of your air intake. If not, it won’t have a good seal and may damage the rubber of your intake. However, it looks great!

Good quality on Universal fitment.
Used on a 89 bronco ii because original air box got destroyed. Stretched original hose and put a short 3" pipe to attach filter. Filter seems of good quality and build. Especially for the price point.

I have baffles in my valve cover and these bleed oil moisture all over valve covers.

Has a 2.5 inch base worked well on my two barrel carburetor however it didn’t give me the hood clearance on my jeep that I was hoping for so I’ve had to switch it out to a shorter air filter. However, if this fits in your application I would recommend it. It is a nice quality air filter for the price point.
