CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your WRX/STI running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.This Part Fits:

O.E quality
Item Package Quantity: 1
Very impressed with the quality. Usually cheaper aftermarket filters are thin and flimsy. This is very durable and much better than what came out of my car. Fit my Odyssey perfectly.

A reliable purchase doing exactly what I expected
Item Package Quantity: 1
Look, you know how it is – what’s a game-changer for one person is just another Tuesday for another. For me, this Puroma Cabin Air Filter with Activated Carbon landed exactly where most good products do: solid and dependable.
It arrived precisely as described, the activated carbon element is there, and it installed without a hitch in my vehicle. The air quality inside definitely feels cleaner, and it's doing its job filtering out the usual suspects. Does it redefine the very concept of cabin air filtration or deliver some earth-shattering innovation? Nah, not really. It’s a well-made, effective replacement that perfectly fulfills its purpose without any fuss or unexpected brilliance.
A reliable purchase doing exactly what I expected. A firm 4 stars.

Easy Cabin Filter Swap For Cleaner Air
Item Package Quantity: 1
I picked up this Puroma cabin air filter to replace the old one in my Honda and it has worked out very well. It fit the housing just like the original, slid in without any forcing, and the whole swap took only a few minutes. The construction feels solid for the price and the edges seal properly so air is not just bypassing the filter.
After installing it, the air from the vents smelled noticeably fresher, especially when using recirculate. The activated carbon layer seems to help cut down on that stale or slightly musty smell that builds up over time. For something that is easy to forget about, changing this filter makes a real difference in everyday driving comfort.
If you have a compatible Honda or Acura and want an affordable replacement that you can install yourself instead of paying dealership prices, this Puroma cabin filter is a very practical option.
