CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E46 M3 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. The Triple-Pass Flow Structure allows the coolant to flow across the core of the radiator three times before exiting for lowest outlet temperatures possible. 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.The CSF E46 M3 radiator is a true "Drop-in fit" design requiring no modifications to install. OE style brackets are all CNC machined and welded for the best durability possible. Inlet/Outlet connections are designed to match the OE connections so you can reuse OEM hoses or aftermarket.

Great inexpensive mod
Very easy to install, the old grill was a little difficult getting out but the new grill fit perfect and easy to install on my son's 2008 E90/328i. Looks great, best $'s for the most bang we've spent so far...

9/10. Very good product considering the price and quality.
Packaging was 10/10. Came in a box, each grille and eyelid was wrapped individually. The grilles were wrapped in foam for protection. Looks pretty good. No immediately noticeable blemishes on my order. Although it doesn't feel as rigid as the OEM one (of course) One thing I noticed tho was there is a crack/break in one of the grilles but it's not noticeable when the hood is shut. Not sure how that will affect how long it will last but it still looks good. Overall a 9/10 just cause of that crack.

Cool and inexpensive.
The original chrome grill bits broke off my 2006 BMW 323i, So I replaced them with these cool matt black ones.
