CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your 1M/135i/335i 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.Shipping Notes

It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34.
I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!
