So my first review wasn't great - and I don't know how to update my first review. I had a small picky concern because the heat shrink tubing wasn't perfect. The owner saw my review and a few days later I received a replacement that the owner had enclosed a note where he had personally worked on my replacement part (this was not needed, but he wanted to show me that he valued the feedback). The replacements workmanship was very worthy of the price. The owner even said he burnt his fingers while making it for me. This level of customer satisfaction is above ad beyond. This is a good company to do business with and very trustworthy. I know if I have a problem they will fix it even when I didn't ask them to. It was personal to them and it showed. I'm currently saving up for my next purchase with them, which will be the intercoolers. I've head really good things about those.

If you’re looking to fix/prevent the dreaded vent line issue, I couldn’t recommend this enough for reactive or proactive maintenance on the Cayenne. I find the value of this kit is worth more than what you pay for a number of reasons. Easy installation that requires minimal tools, aluminum flange fittings that will remain integral for the life of the engine, robust design so you don’t have to worry about plastic breaking during install and most importantly, no need to take the intake off. This top notch assembly includes everything you want plus a Radhaus sticker! Josh is a great guy and will make sure you’re taken care of very quickly, so don’t get analysis paralysis… Just spend the money. You’ll be doing it once and for all, the right way.

Thanks!

Easy install, work as it should for now, just a little pricey but convenience is worth it compared to the original part routing under the intake and so forth.

It was in fantastic condition and arrived quickly and well packed. No complaints.

I initially made up my own replacement coolant vent line kit and it held up for a few months but developed a leak from the plastic fittings again. I ordered the Radhaus kit and the machined fittings are much better quality and appear they’ll last. Dealing with Josh was a pleasure. I live in Canada and he helped make the transaction smooth and quick. Fantastic customer service and product.

Item was great and perfect fit.

That was the easiest installation I’ve ever done when it comes to coolant repair. You guys save me problems in the future with that amazing bypass hose whoever designed it thank you very much.

I just had the Coolant Vent Line Bypass Kit installed. So far so good. It was a simple install for my mechanic. Saved a ton of labor and time vs. the OEM vent line which is a bit labor intensive to install. This kit looks solid and appears to be of sturdy quality... especially compared to the POS stock coolant vent line. Of course time will tell, but the kit and it's parts look like they'll last. Thanks Rad Haus.

It work!

I had the OEM spaghetti venting go without warning and had to be toed home.
When I saw the tubing used and its routing I said there had to be a better way.
At the time there was not. As soon as the Bypass Kit was available I ordered one. When it arrived, it looked well-made and designed. My mechanic (Autobahn Motors in Santa Rosa, CA) installed it and confirmed it was well made and easy to install. The kit and the labor to install it was less than just the labor for the OEM part and I am confident it will outlast the rest of the car.
