Outstanding quality and value !
The quality is outstanding ! Just a upper or lower radiator hose is 35 bucks from auto parts store here you get it all for 50. It says it doesn't fit a 06 Subaru outback legacy wagon 2.5 but it does ! I could see they were identical hoses so I took a chance and bang! Don't think I would trust the clamps I just reused the old ones. My only regret is I didn't get the purple 💜

Awesome Bang for Buck
Look and work great! Bottom radiator hose was long and needed a trim but that's perfectly fine. Worth the money!

Good quality hose. Hit or miss for fitment
The hoses are of good quality, but I had some fitment issues for my stock 06 STI. The pieces that fit will pay for it themselves, as the OEM hoses are easily 5x the cost. However, you might waste a bunch of time trying to get things to work and then waiting for the OEM parts to come in for what does not fit. My experience with fitment for 06 STI: -Top Radiator Hose. Perfect. -Bottom Radiator Hose. Slightly too long, bend a bit out of place. Slightly Kinked. Should not affect Function. -Reservoir to Radiator and Expansion Tank hoses (2 hoses). A bend is in the wrong direction, but enough slack in the long lines so should not be an issue. -Reservoir to Turbo. Hose too short. Could not use. -Reservoir to Engine (L elbow). Wrong Size Hose (hose inner diameter too small). Could not use. -Passenger side PCV hose. Slightly too short ~1/2in. Could work but a bit stretched. -PCV hoses going to front of engine. Perfect -Driver side PCV hose. Wrong hose or 2006 STI should fit 04-05 STIs. -Recirculation Valve hose. Seems to be right size and length but did not attempt to install. -Mystery hose. Could not figure out what the last hose is for... All outer hose diameters will be larger than OEM hoses, so all the factory hose clips and retainers will not fit these.

close enough
For 2005 wrx (actually the saabaru 9-2x aero), these fit OK. Had to trim 0.5 inch off top hose, radiator side. Trimmed 1 inch off bottom hose, engine side. The top seems just a little short (about 0.5 inch) in the main straight section, so it pulls at the bends on both ends. The clamps are a not as nice as the ones I've installed with similar mishimoto hoses, but they work fine. Overall, a good value and they look nice. Hopefully they'll last many years like the mishimoto silicone hoses.

Great kit, has some tiny issues most mechanically inclined people can work around.
Can't beat the price, BUT: The included clamps aren't very good. They strip very easily. The upper and lower large coolant lines that go from the radiator to the engine were too long and needed trimming, just don't trim too much. The lines from the reservoir that sits over the turbo are much thicker than the original and don't fit into the stock mounting clamps without a bit of coaxing. Otherwise great hose kit, would def buy again.

Does not fit!
I was super excited to upgrade my old and trashed coolant hoses. I liked the quality of these new hoses but WOW! They don’t fit at all and it’s honesty such a joke to even try to get them on. The clamps that come with the hoses completely broke after tightening. I’d rather use a zip tie and call it good. The hose quality is great but it’s not long enough to reach and the bends are all in the wrong places:( I’m now taking a trip to my local auto one to buy an adapter to extend the top hose. Don’t even get me started on the bottom hose. As you can see. They’re both kinked horribly. First picture shows the hose to about 4 inches too short. Second picture sheds some light on the most insane kink I’ve ever experienced. Last pic is the bottom hose… it should just be a 90° bend but it’s twisted and totally wrong.

They can hold a good amount of pressure
Had my thermostat go out on my 07 Impreza Hoses were installed 800 miles prior Had to drive about 46 miles with the engine sitting at 217°f and held strong , some of the best hoses I have owned for the price and the silicone definitely adds a punch.

Too short
Very good quality but useless, because most of the hoses are too short, at least for my 2006 wrx
