pretty good for price!
Great item with easy install, drops right in for a perfect fit! the quality is up there for its money, but certainly isn’t going to be your top of the line. however it gets the job done and has a prettt decent air flow for its price!

Looks just like OEM
Fit great in 2018 Honda Civic. Easy to install and looked just like the OEM one (but much cleaner). Would recommend
