CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your Audi Quattro/B1/B2/B3/B4 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.

10/10 Great suit , great price
Size: X-Small, Color: Red, Size: X-Small, Color: Red
Absolutely stunning for the price. Very flexible and good fit. I wish the XS was just a bit smaller but it's good. Middle of the ground with thickness it's not a cheap thing costume feel but it's not your typical heavy suit. Which I much prefer. It's lightweight but not cheap. For the price you can't ask for a better suit. I was thinking it was more of a one time use, but it's a very good long term suit. Feels very well and allows great mobility. I featherweight conceal carry and it's very easy to hide my pistol in the suit because of its flexibility. 10/10 would definitely recommend

Good Suit
Size: X-Small, Color: Black
This suit is pretty nice. The fabric isn't extremely thin and cheap-feeling, and it fits really well. The shipping was really fast too. My son is 5'9" and weighs about 150 lbs. We ordered a medium first, but it was too big, so we returned it and ordered an extra small. The extra small fits perfectly.

It's a fun/unusual color, but not "celery"
Size: Medium, Color: Celery Green, Size: Medium, Color: Celery Green
Can't comment on the fit because we didn't take it out of the bag. I gave it 4 stars because 𝙦𝙪𝙖𝙡𝙞𝙩𝙮 of the suit looks really nice through the plackaging, but we didn't open it up and try it on because the color could not be further from what we were expecting. It's actually a really cool and unusual fun fabric, but not really describable as any shade of green which is what I was going for. It's more of a beige tweed whose tiny plaid upon careful examination even has slightly blue threads.. or is that lavender? In fairness to the manufacturer, I tried and tried to get a photo with lighting that accurately represents this fun and unusual color to no avail. For a proper review I guess I should have my son put it on and take a picture in daylight. But they do need to change the color name at least to "champagne tweed" or something. No idea whose job it was to call this color "celery". ;p

Sharp and Expensive Quality Tuxedo for special events!!
Size: Small, Color: Black
I researched for several tuxedos for my son's prom, we chose this one, and I'm very glad that we did! The fit is nice, the durability is great. Very classy looking! The quality is really surprising for this price, it looks like a $200 dollar suit. My son is very picky and was very pleased with this tuxedo. The seams are very good and all the buttons are correct. We did receive the tie and everything that was supposed to be with it as I know reviews were saying they didn't get certain things but we did. I really like the adjustable waste because my son is very slim, but tall and has a long torso. This Tuxedo allowed him to be super excited that we have everything we need for his first prom! True to color as we purchased the black and it is sharp!

Impressive suit for the price
Size: X-Large, Color: Navy Blue
Order suit in my normal size (44R) and it fit perfectly. I’m 6’1” and the pant length set at the correct level. Quality fabric and stitching is well finished. Pants are comfortable at the waist with enough flex to be forgiving. Very good deal for the price…suit, vest and tie.
